The AFPM generator, however, has a history of overheating on the surface of the stator, so that power production decreases significantly. A proper cooling system, therefore, is needed.

In this paper, we proposed a newly developed conductive-type cooling system using a heat pipe wound to the stator of a 2.5 MW AFPM generator installed on an offshore wind turbine. The numerical results showed that the temperatures on the stator surface using convective-type cooling system and the proposed conductive-type cooling system at thermal saturation were 60 and 76°C, respectively, which met the requirements for power production. The temperatures of the permanent magnet cased by the radiant heating from the stator surface were 53°C and 66°C, respectively, in each case. As a result, the permanent magnet did not reach the malfunction temperature. Although the cooling temperatures in the case of the conductive-type cooling system were higher than that of the convective-type cooling system, the relatively small size of the water pump and radiators make a light-weight design of the AFPM generator possible. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wind%20turbine" title="wind turbine">wind turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=axial%20flux%20permanent%20magnet%20%28AFPM%29%20generator" title=" axial flux permanent magnet (AFPM) generator"> axial flux permanent magnet (AFPM) generator</a>, <a href="https://publications.waset.org/abstracts/search?q=conductive-type%20cooling%20system" title=" conductive-type cooling system"> conductive-type cooling system</a> </p> <a href="https://publications.waset.org/abstracts/14914/feasibility-study-on-a-conductive-type-cooling-system-for-an-axial-flux-permanent-magnet-generator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14914.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">327</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2249</span> Heat Transfer in Direct-Driven Generator for Large-Scaled Wind Turbine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dae-Gyun%20Ahn">Dae-Gyun Ahn</a>, <a href="https://publications.waset.org/abstracts/search?q=Eun-Teak%20Woo"> Eun-Teak Woo</a>, <a href="https://publications.waset.org/abstracts/search?q=Yun-Hyun%20Cho"> Yun-Hyun Cho</a>, <a href="https://publications.waset.org/abstracts/search?q=Seung-Ho%20Han"> Seung-Ho Han</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For the sustainable development of wind energy, energy industries have invested in the development of highly efficient wind generators such as the Axial Flux Permanent Magnet (AFPM) generator.

This paper presents one of the most important characteristics in the design process of the AFPM device, which is a recent issue. To design AFPM machine, the predicting electromagnetic forces between the permanent magnets and stator is important. Because of the magnitude of electromagnetic force affects many characteristics such as machine size, noise, vibration, and quality of output power. Theoretically, this force is canceled by the equilibrium of force when it is in the middle of the gap, but it is inevitable to deviate due to manufacturing problems in actual machine. Such as large scale wind generator, because of the huge attractive force between rotor and stator disks, this is more serious in getting large power applications such as large. This paper represents the characteristics of Double-Stator Inner –Rotor AFPM machines when it has rotor eccentricity. And, unbalanced air-gap and inclined air-gap condition which is caused by rotor offset and tilt in a double-stator single inner-rotor AFPM machine are each studied in electromagnetic and mechanical aspects. The output voltage and cogging torque under un-normal air-gap condition of AF machines are firstly calculated using a combined analytical and numerical methods, followed by a structure analysis to study the effect to mechanical stress, deformation and bending forces on bearings. Results and conclusions given in this paper are instructive for the successful development of AFPM machines. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=axial%20flux%20permanent%20magnet%20machine" title="axial flux permanent magnet machine">axial flux permanent magnet machine</a>, <a href="https://publications.waset.org/abstracts/search?q=inclined%20air%20gap" title=" inclined air gap"> inclined air gap</a>, <a href="https://publications.waset.org/abstracts/search?q=unbalanced%20air%20gap" title=" unbalanced air gap"> unbalanced air gap</a>, <a href="https://publications.waset.org/abstracts/search?q=rotor%20eccentricity" title=" rotor eccentricity"> rotor eccentricity</a> </p> <a href="https://publications.waset.org/abstracts/68826/characteristics-of-double-stator-inner-rotor-axial-flux-permanent-magnet-machine-with-rotor-eccentricity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68826.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">219</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2246</span> Feasibility Study on Hybrid Multi-Stage Direct-Drive Generator for Large-Scale Wind Turbine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jin%20Uk%20Han">Jin Uk Han</a>, <a href="https://publications.waset.org/abstracts/search?q=Hye%20Won%20Han"> Hye Won Han</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyo%20Lim%20Kang"> Hyo Lim Kang</a>, <a href="https://publications.waset.org/abstracts/search?q=Tae%20An%20Kim"> Tae An Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Seung%20Ho%20Han"> Seung Ho Han</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Direct-drive generators for large-scale wind turbine, which are divided into AFPM(Axial Flux Permanent Magnet) and RFPM(Radial Flux Permanent Magnet) type machine, have attracted interest because of a higher energy density in comparison with gear train type generators. Each type of the machines provides distinguishable geometrical features such as narrow width with a large diameter for the AFPM-type machine and wide width with a certain diameter for the RFPM-type machine. When the AFPM-type machine is applied, an increase of electric power production through a multi-stage arrangement in axial direction is easily achieved. On the other hand, the RFPM-type machine can be applied by using its geometric feature of wide width. In this study, a hybrid two-stage direct-drive generator for 6.2MW class wind turbine was proposed, in which the two-stage AFPM-type machine for 5 MW was composed of two models arranged in axial direction with a hollow shape topology of the rotor with annular disc, the stator and the main shaft mounted on coupled slew bearings. In addition, the RFPM-type machine for 1.2MW was installed at the empty space of the rotor. Analytic results obtained from an electro-magnetic and structural interaction analysis showed that the structural weight of the proposed hybrid two-stage direct-drive generator can be achieved as 155tonf in a condition satisfying the requirements of structural behaviors such as allowable air-gap clearance and strength. Therefore, it was sure that the 6.2MW hybrid two-stage direct-drive generator is competitive than conventional generators.

Khan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper introduces dual rotor axial flux machines with surface mounted and spoke type ferrite permanent magnets with concentrated windings; they are introduced as alternatives to a generator with surface mounted Nd-Fe-B magnets. The output power, voltage, speed and air gap clearance for all the generators are identical. The machine designs are optimized for minimum mass using a population-based algorithm, assuming the same efficiency as the Nd-Fe-B machine. A ﬁnite element analysis (FEA) is applied to predict the performance, emf, developed torque, cogging torque, no load losses, leakage flux and efficiency of both ferrite generators and that of the Nd-Fe-B generator. To minimize cogging torque, different rotor pole topologies and different pole arc to pole pitch ratios are investigated by means of 3D FEA. It was found that the surface mounted ferrite generator topology is unable to develop the nominal electromagnetic torque, and has higher torque ripple and is heavier than the spoke type machine. Furthermore, it was shown that the spoke type ferrite permanent magnet generator has favorable performance and could be an alternative to rare-earth permanent magnet generators, particularly in wind energy applications. Finally, the analytical and numerical results are verified using experimental results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=axial%20%EF%AC%82ux" title="axial ﬂux">axial ﬂux</a>, <a href="https://publications.waset.org/abstracts/search?q=permanent%20magnet%20generator" title=" permanent magnet generator"> permanent magnet generator</a>, <a href="https://publications.waset.org/abstracts/search?q=dual%20rotor" title=" dual rotor"> dual rotor</a>, <a href="https://publications.waset.org/abstracts/search?q=ferrite%20permanent%20magnet%20generator" title=" ferrite permanent magnet generator"> ferrite permanent magnet generator</a>, <a href="https://publications.waset.org/abstracts/search?q=%EF%AC%81nite%20element%20analysis" title=" ﬁnite element analysis"> ﬁnite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20turbines" title=" wind turbines"> wind turbines</a>, <a href="https://publications.waset.org/abstracts/search?q=cogging%20torque" title=" cogging torque"> cogging torque</a>, <a href="https://publications.waset.org/abstracts/search?q=population-based%20algorithms" title=" population-based algorithms"> population-based algorithms</a> </p> <a href="https://publications.waset.org/abstracts/79585/designing-and-prototyping-permanent-magnet-generators-for-wind-energy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79585.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">151</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2244</span> Magnetic End Leakage Flux in a Spoke Type Rotor Permanent Magnet Synchronous Generator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Petter%20Eklund">Petter Eklund</a>, <a href="https://publications.waset.org/abstracts/search?q=Jonathan%20Sj%C3%B6lund"> Jonathan Sjölund</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Eriksson"> Sandra Eriksson</a>, <a href="https://publications.waset.org/abstracts/search?q=Mats%20Leijon"> Mats Leijon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The spoke type rotor can be used to obtain magnetic flux concentration in permanent magnet machines. This allows the air gap magnetic flux density to exceed the remanent flux density of the permanent magnets but gives problems with leakage fluxes in the magnetic circuit. The end leakage flux of one spoke type permanent magnet rotor design is studied through measurements and finite element simulations. The measurements are performed in the end regions of a 12 kW prototype generator for a vertical axis wind turbine. The simulations are made using three dimensional finite elements to calculate the magnetic field distribution in the end regions of the machine. Also two dimensional finite element simulations are performed and the impact of the two dimensional approximation is studied. It is found that the magnetic leakage flux in the end regions of the machine is equal to about 20% of the flux in the permanent magnets. The overestimation of the performance by the two dimensional approximation is quantified and a curve-fitted expression for its behavior is suggested. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=end%20effects" title="end effects">end effects</a>, <a href="https://publications.waset.org/abstracts/search?q=end%20leakage%20flux" title=" end leakage flux"> end leakage flux</a>, <a href="https://publications.waset.org/abstracts/search?q=permanent%20magnet%20machine" title=" permanent magnet machine"> permanent magnet machine</a>, <a href="https://publications.waset.org/abstracts/search?q=spoke%20type%20rotor" title=" spoke type rotor"> spoke type rotor</a> </p> <a href="https://publications.waset.org/abstracts/65632/magnetic-end-leakage-flux-in-a-spoke-type-rotor-permanent-magnet-synchronous-generator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65632.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">332</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2243</span> Comparison of Different Electrical Machines with Permanent Magnets in the Stator for Use as an Industrial Drive</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcel%20Lehr">Marcel Lehr</a>, <a href="https://publications.waset.org/abstracts/search?q=Andreas%20Binder"> Andreas Binder</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper compares three different permanent magnet synchronous machines (Doubly-Salient-Permanent-Magnet-Machine (DSPM), Flux-Reversal-Permanent-Magnet-Machine (FRPM), Flux-Switching-Permanent-Magnet-Machine (FSPM)) with the permanent magnets in the stator of the machine for use as an industrial drive for 400 V Y, 45 kW and 1000 ... 3000 min-1.

Therefore, an FSPM prototype was built, tested on a test bench and finally compared with an already built conventional permanent magnet synchronous machine (PMSM) of the same size (stator outer diameter dso = 314 mm, axial length lFe = 180 mm) and rating with surface-mounted rotor magnets. These measurements show that the conventional PMSM and the FSPM machine are roughly equivalent in their electrical behavior. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=doubly-salient-permanent-magnet-machine" title="doubly-salient-permanent-magnet-machine">doubly-salient-permanent-magnet-machine</a>, <a href="https://publications.waset.org/abstracts/search?q=flux-reversal-permanent-magnet-machine" title=" flux-reversal-permanent-magnet-machine"> flux-reversal-permanent-magnet-machine</a>, <a href="https://publications.waset.org/abstracts/search?q=flux-switching-permanent-magnet-machine" title=" flux-switching-permanent-magnet-machine"> flux-switching-permanent-magnet-machine</a>, <a href="https://publications.waset.org/abstracts/search?q=industrial%20drive" title=" industrial drive"> industrial drive</a> </p> <a href="https://publications.waset.org/abstracts/61399/comparison-of-different-electrical-machines-with-permanent-magnets-in-the-stator-for-use-as-an-industrial-drive" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61399.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">371</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2242</span> CFD-Parametric Study in Stator Heat Transfer of an Axial Flux Permanent Magnet Machine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Rasekh">Alireza Rasekh</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Sergeant"> Peter Sergeant</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan%20Vierendeels"> Jan Vierendeels</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper copes with the numerical simulation for convective heat transfer in the stator disk of an axial flux permanent magnet (AFPM) electrical machine. Overheating is one of the main issues in the design of AFMPs, which mainly occurs in the stator disk, so that it needs to be prevented. A rotor-stator configuration with 16 magnets at the periphery of the rotor is considered. Air is allowed to flow through openings in the rotor disk and channels being formed between the magnets and in the gap region between the magnets and the stator surface. The rotating channels between the magnets act as a driving force for the air flow. The significant non-dimensional parameters are the rotational Reynolds number, the gap size ratio, the magnet thickness ratio, and the magnet angle ratio. The goal is to find correlations for the Nusselt number on the stator disk according to these non-dimensional numbers. Therefore, CFD simulations have been performed with the multiple reference frame (MRF) technique to model the rotary motion of the rotor and the flow around and inside the machine. A minimization method is introduced by a pattern-search algorithm to find the appropriate values of the reference temperature. It is found that the correlations are fast, robust and is capable of predicting the stator heat transfer with a good accuracy. The results reveal that the magnet angle ratio diminishes the stator heat transfer, whereas the rotational Reynolds number and the magnet thickness ratio improve the convective heat transfer. On the other hand, there a certain gap size ratio at which the stator heat transfer reaches a maximum. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AFPM" title="AFPM">AFPM</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD" title=" CFD"> CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=magnet%20parameters" title=" magnet parameters"> magnet parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=stator%20heat%20transfer" title=" stator heat transfer"> stator heat transfer</a> </p> <a href="https://publications.waset.org/abstracts/56746/cfd-parametric-study-in-stator-heat-transfer-of-an-axial-flux-permanent-magnet-machine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56746.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">250</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2241</span> Development of an Analytical Model for a Synchronous Permanent Magnet Generator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20Sahbani">T.

The study conducted in this paper examines the influence of temperature on the performance of the permeant magnet linear generator, an integral and pivotal component within the system. This research places particular emphasis on the Neodymium Iron Boron (NdFeB) permanent magnet, which serves as a source of magnetic field for the linear generator. In this study, an internal combustion engine that tends to produce heat is connected to a generator. Considering the temperatures rise from both the combustion process and the thermal contributions of current-carrying conductors and frictional forces. Utilizing Computational Fluid Dynamics (CFD) method, a thermal model of the (NdFeB) magnet within the linear generator is constructed and analyzed. Furthermore, the temperature field is examined to ensure that the linear generator operates under stable conditions without the risk of demagnetization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=free%20piston%20engine" title="free piston engine">free piston engine</a>, <a href="https://publications.waset.org/abstracts/search?q=permanent%20magnet" title=" permanent magnet"> permanent magnet</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20generator" title=" linear generator"> linear generator</a>, <a href="https://publications.waset.org/abstracts/search?q=demagnetization" title=" demagnetization"> demagnetization</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a> </p> <a href="https://publications.waset.org/abstracts/185409/temperature-rises-characteristics-of-distinct-double-sided-flat-permanent-magnet-linear-generator-for-free-piston-engines-for-hybrid-vehicles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185409.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">56</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2237</span> Novel Stator Structure Switching Flux Permanent Magnet Motor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mengjie%20Shen">Mengjie Shen</a>, <a href="https://publications.waset.org/abstracts/search?q=Jianhua%20Wu"> Jianhua Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Chun%20Gan"> Chun Gan</a>, <a href="https://publications.waset.org/abstracts/search?q=Lifeng%20Zhang"> Lifeng Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Qingguo%20Sun"> Qingguo Sun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Switching flux permanent magnet (SFPM) motor has doubly salient structure which lead to high torque ripple, and also has cogging torque as a permanent magnet motor.

Generally, the permanent magnet motor used the ferrite magnets has lower output power and efficiency than a rare-earth magnet motor, because the ferrite magnet has lower magnetic energy than the rare-earth magnet. Nevertheless, the ferrite magnet motor is used to many industrial products owing to cost effectiveness. In this paper, the authors propose a high power density design of the ferrite permanent magnet synchronous motor. Furthermore, because the motor design has to be taken a manufacturing process into account, the design is simulated by using the finite element method for analyzing the demagnetization, the magnetizing, and the structure stiffness. Especially, the magnet shape and dimensions are decided for satisfying these properties. Finally, the authors design an optimal motor for applying our system.

The industry has been moving towards higher wind generator power ratings, in particular, off-shore generator ratings. Current off-shore wind turbine generators are in the power range of 10 to 12 MW. Unlike traditional induction motors, slow-speed permanent magnet surface mounted (PMSM) high-power generators are relatively challenging and designed differently. In this paper, PMSM generator design features have been discussed and analysed. The focus attention is on armature windings, harmonics, and permanent magnet. For the power ratings under consideration, the generator air-gap diameters are in the range of 8 to 10 meters, and active material weigh ~60 tons and above. Therefore, material weight becomes one of the critical parameters. Particle Swarm Optimization (PSO) technique is used for weight reduction and performance improvement. Four independent variables have been considered, which are air gap diameter, stack length, magnet thickness, and winding current density. To account for core and teeth saturation, preventing demagnetization effects due to short circuit armature currents, and maintaining minimum efficiency, suitable penalty functions have been applied. To check for performance satisfaction, a detailed analysis and 2D flux plotting are done for the optimized design. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=offshore%20wind%20generator" title="offshore wind generator">offshore wind generator</a>, <a href="https://publications.waset.org/abstracts/search?q=PMSM" title=" PMSM"> PMSM</a>, <a href="https://publications.waset.org/abstracts/search?q=PSO%20optimization" title=" PSO optimization"> PSO optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20optimization" title=" design optimization"> design optimization</a> </p> <a href="https://publications.waset.org/abstracts/113747/design-analysis-and-optimization-of-10-mw-permanent-magnet-surface-mounted-off-shore-wind-generator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113747.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">155</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2232</span> Permanent Magnet Synchronous Generator: Unsymmetrical Point Operation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20Pistelok">P.

Therefore, several topologies have been proposed like the PM exited flux switching machine, hybrid excited flux switching type, and so on. Recently, a novel laminated segmented rotor flux switching permanent magnet machine was introduced. It features flux barriers on rotor structure to enhance the performances of machine including torque ripple reduction and also torque and efficiency improvements at the same time. This is while, the design of barriers was not optimized by the authors. Therefore, in this paper three coefficients regarding the position of the barriers are considered for optimization. The effect of each coefficient on the performance of this machine is investigated by finite element method and finally an optimized design of flux barriers based on these three coefficients is proposed from different points of view including electromagnetic torque maximization and cogging torque/torque ripple minimization. At optimum design from maximum developed torque aspect, this machine generates 0.65 Nm torque higher than that of the not-optimized design with an almost 0.4 % improvement in efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title="finite element analysis">finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=FSPM" title=" FSPM"> FSPM</a>, <a href="https://publications.waset.org/abstracts/search?q=laminated%20segmented%20rotor%20flux%20switching%20permanent%20magnet%20machine" title=" laminated segmented rotor flux switching permanent magnet machine"> laminated segmented rotor flux switching permanent magnet machine</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a> </p> <a href="https://publications.waset.org/abstracts/127513/optimization-of-a-flux-switching-permanent-magnet-machine-using-laminated-segmented-rotor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127513.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">230</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2228</span> Sensitivity Analysis of External-Rotor Permanent Magnet Assisted Synchronous Reluctance Motor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hadi%20Aghazadeh">Hadi Aghazadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Ebrahim%20Afjei"> Seyed Ebrahim Afjei</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Siadatan"> Alireza Siadatan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a proper approach is taken to assess a set of the most effective rotor design parameters for an external-rotor permanent magnet assisted synchronous reluctance motor (PMaSynRM) and therefore to tackle the design complexity of the rotor structure. There are different advantages for introducing permanent magnets into the rotor flux barriers, some of which are to saturate the rotor iron ribs, to increase the motor torque density and to improve the power factor. Moreover, the d-axis and q-axis inductances are of great importance to simultaneously achieve maximum developed torque and low torque ripple. Therefore, sensitivity analysis of the rotor geometry of an 8-pole external-rotor permanent magnet assisted synchronous reluctance motor is performed. Several magnetically accurate finite element analyses (FEA) are conducted to characterize the electromagnetic performance of the motor. The analyses validate torque and power factor equations for the proposed external-rotor motor. Based upon the obtained results and due to an additional term, permanent magnet torque, added to the reluctance torque, the electromagnetic torque of the PMaSynRM increases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=permanent%20magnet%20assisted%20synchronous%20reluctance%20motor" title="permanent magnet assisted synchronous reluctance motor">permanent magnet assisted synchronous reluctance motor</a>, <a href="https://publications.waset.org/abstracts/search?q=flux%20barrier" title=" flux barrier"> flux barrier</a>, <a href="https://publications.waset.org/abstracts/search?q=flux%20carrier" title=" flux carrier"> flux carrier</a>, <a href="https://publications.waset.org/abstracts/search?q=electromagnetic%20torque" title=" electromagnetic torque"> electromagnetic torque</a>, <a href="https://publications.waset.org/abstracts/search?q=and%20power%20factor" title=" and power factor"> and power factor</a> </p> <a href="https://publications.waset.org/abstracts/85367/sensitivity-analysis-of-external-rotor-permanent-magnet-assisted-synchronous-reluctance-motor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85367.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">331</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2227</span> Estimation of Fourier Coefficients of Flux Density for Surface Mounted Permanent Magnet (SMPM) Generators by Direct Search Optimization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ramakrishna%20Rao%20Mamidi">Ramakrishna Rao Mamidi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is essential for Surface Mounted Permanent Magnet (SMPM) generators to determine the performance prediction and analyze the magnet’s air gap flux density wave shape. The flux density wave shape is neither a pure sine wave or square wave nor a combination. This is due to the variation of air gap reluctance between the stator and permanent magnets. The stator slot openings and the number of slots make the wave shape highly complicated. To reduce the complexity of analysis, approximations are made to the wave shape using Fourier analysis. In contrast to the traditional integration method, the Fourier coefficients, an and bn, are obtained by direct search method optimization. The wave shape with optimized coefficients gives a wave shape close to the desired wave shape. Harmonics amplitudes are worked out and compared with initial values. It can be concluded that the direct search method can be used for estimating Fourier coefficients for irregular wave shapes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=direct%20search" title="direct search">direct search</a>, <a href="https://publications.waset.org/abstracts/search?q=flux%20plot" title=" flux plot"> flux plot</a>, <a href="https://publications.waset.org/abstracts/search?q=fourier%20analysis" title=" fourier analysis"> fourier analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=permanent%20magnets" title=" permanent magnets"> permanent magnets</a> </p> <a href="https://publications.waset.org/abstracts/139812/estimation-of-fourier-coefficients-of-flux-density-for-surface-mounted-permanent-magnet-smpm-generators-by-direct-search-optimization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139812.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">216</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2226</span> A Review on Control of a Grid Connected Permanent Magnet Synchronous Generator Based Variable Speed Wind Turbine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eman%20M.%20Eissa">Eman M.

The permanent magnet linear synchronous generator (PMLSG) allows for direct drive without the need for a mechanical device. Therefore, the PMLSG is well suited to translational applications, such as wave energy converters and free piston energy converters. This manuscript compares the effects of different magnetization patterns on the characteristics of double-sided PMLSGs in slotless stator structures. The Halbach array has a higher flux density in air-gap than the Vertical array, and the advantages of its performance and efficiency are widely known. To verify the advantage of Halbach array, we apply a finite element method (FEM) and analytical method. In general, a FEM and an analytical method are used in the electromagnetic analysis for determining model characteristics, and the FEM is preferable to magnetic field analysis. However, the FEM is often slow and inflexible. On the other hand, the analytical method requires little time and produces accurate analysis of the magnetic field. Therefore, the flux density in air-gap and the Back-EMF can be obtained by FEM. In addition, the results from the analytical method correspond well with the FEM results. The model of the Halbach array reveals less copper loss than the model of the Vertical array, because of the Halbach array’s high output power density. The model of the Vertical array is lower core loss than the model of Halbach array, because of the lower flux density in air-gap. Therefore, the current density in the Vertical model is higher for identical power output. The completed manuscript will include the magnetic field characteristics and structural features of both models, comparing various results, and specific comparative analysis will be presented for the determination of the best model for application in a wave energy converting system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wave%20energy%20converter" title="wave energy converter">wave energy converter</a>, <a href="https://publications.waset.org/abstracts/search?q=permanent%20magnet%20linear%20synchronous%20generator" title=" permanent magnet linear synchronous generator"> permanent magnet linear synchronous generator</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title=" finite element method"> finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=analytical%20method" title=" analytical method"> analytical method</a> </p> <a href="https://publications.waset.org/abstracts/65820/effects-of-magnetization-patterns-on-characteristics-of-permanent-magnet-linear-synchronous-generator-for-wave-energy-converter-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65820.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">301</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2222</span> Magnetic Field Analysis of External Rotor Permanent-Magnet Synchronous Motors with Non Magnetic Rotor Core</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mabrak%20Samir">Mabrak Samir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The motor performance created by permanent magnetic in a slotless air-gap of a surface mounted permanent-magnet synchronous motor with non magnetic rotor and either sinusoidal or mixed (quasi-Halbatch) magnetization is presented in this paper using polar coordinates.

PMSM is widely used in industrial application, wind power plant and automotive industry. Since the PMSM are used in different environment condition, the long-term effect of NdFeB-based magnets at high temperatures and corrosion behavior has to be studied due to irreversible loss of magnetic properties. In this paper, the effect of magnetic properties due to corrosion and increasing temperature in the climatic chamber has been presented. The magnetic moment and magnetic field of the magnet were studied experimentally. <p class="card-text"><strong>Keywords:</strong> <a
