Terminal voltage of battery reduces with the S.o.C. This results in the downward shift of torque-speed curve of E-motor and increased copper losses in E-motor. By introducing a buck-boost inverter between the battery and E-motor, an additional degree of freedom was achieved. By boosting the AC voltage, the dependency of voltage sag on the performance of E-motor was eliminated. A strategy was also proposed for the operation of the buck-boost inverter to minimize copper and iron losses in E-motor to maximize efficiency. MATLAB-SIMULINK model of E-drive was used to obtain simulation results. The temperature rise in the E-motor was reduced by 14% for a 10% increase in AC voltage. From the results, it was observed that a 20% increase in AC voltage can result in improvement of running torque and maximum torque of E-motor by 44%. Hence it was concluded that using a buck-boost inverter for E-drive significantly improves both performance and efficiency of E-motor. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=buck-boost" title="buck-boost">buck-boost</a>, <a href="https://publications.waset.org/abstracts/search?q=E-motor" title=" E-motor"> E-motor</a>, <a href="https://publications.waset.org/abstracts/search?q=battery" title=" battery"> battery</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage%20sag" title=" voltage sag"> voltage sag</a> </p> <a href="https://publications.waset.org/abstracts/67508/buck-boost-inverter-to-improve-the-efficiency-and-performance-of-e-motor-by-reducing-the-influence-of-voltage-sag-of-battery-on-the-performance-of-e-motor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67508.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">399</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">954</span> Determination of Suitability Between Single Phase Induction Motor and Load</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nakarin%20Prempri">Nakarin Prempri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Single-phase induction motors are widely used in industry. Most manufacturing processes use capacitor-run single-phase induction motors to drive mechanical loads. The selection of a suitable motor for driving is important. The optimum operating range of the motor can help the motor operate efficiently. Thus, this paper presents an operating range analysis of capacitor-run single-phase induction motors and a determination of suitability between motor and mechanical loads. an observational study found that the optimum operating range of the motor can be used to determine the suitability between the motor and the mechanical load.

This necessitates proper thermal management of the electric motors. The main focus of this paper is to compare the steady state thermal analysis of a conventional 20 kW 8/6 Switched Reluctance Motor (SRM) with that of an Induction Motor and Inset Permanent Magnet (IPM) motor of the same rating. The goal is to develop a proper thermal model of the three types of models for Finite Element Thermal Analysis. JMAG software is used for the development and simulation of the thermal models. The results show that the induction motor is subjected to more heating when used for electric vehicle application constantly, compared to the SRM and IPM. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electric%20vehicles" title="electric vehicles">electric vehicles</a>, <a href="https://publications.waset.org/abstracts/search?q=induction%20motor" title=" induction motor"> induction motor</a>, <a href="https://publications.waset.org/abstracts/search?q=inset%20permanent%20magnet%20motor" title=" inset permanent magnet motor"> inset permanent magnet motor</a>, <a href="https://publications.waset.org/abstracts/search?q=loss%20models" title=" loss models"> loss models</a>, <a href="https://publications.waset.org/abstracts/search?q=switched%20reluctance%20motor" title=" switched reluctance motor"> switched reluctance motor</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20analysis" title=" thermal analysis"> thermal analysis</a> </p> <a href="https://publications.waset.org/abstracts/99775/comparison-of-the-thermal-characteristics-of-induction-motor-switched-reluctance-motor-and-inset-permanent-magnet-motor-for-electric-vehicle-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99775.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">224</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">952</span> Optimal Control of DC Motor Using Linear Quadratic Regulator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Meetty%20Tomy">Meetty Tomy</a>, <a href="https://publications.waset.org/abstracts/search?q=Arxhana%20G%20Thosar"> Arxhana G Thosar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper provides the implementation of optimal control for an armature-controlled DC motor.

Objectives of Study: The Fine Motor and Executive Function assessment tool (FiM&EF) was developed to answer the question, ‘Do the fine motor skill deficits in children with ADHD come from their fine motor problems or is it caused by their executive function problems?’. This paper describes the development of a new assessment of Fine Motor and Executive Function (FiM &EF) needed by primary school students with ADHD aged 6-12 years with ADHD. Methods: A study on the content validity established through a survey of a panel of nine experts is explained in detail. Findings: Most the experts agreed such an assessment was needed and two items were deleted as a result of experts’ feedback. Relevance to Clinical Practice: Distinguishing the main reason of fine motor problem in these children could help the clinician for their therapy plans. Knowledge on the influence of executive functioning on fine motor ability in selected age children with ADHD would provide a clearer clinical picture of the fine motor capabilities and executive function for these children. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=children%20with%20ADHD" title="children with ADHD">children with ADHD</a>, <a href="https://publications.waset.org/abstracts/search?q=executive%20function" title=" executive function"> executive function</a>, <a href="https://publications.waset.org/abstracts/search?q=fine%20motor" title=" fine motor"> fine motor</a>, <a href="https://publications.waset.org/abstracts/search?q=test" title=" test"> test</a> </p> <a href="https://publications.waset.org/abstracts/77892/development-a-fine-motor-and-executive-function-assessment-fimef-for-assessing-school-aged-children-with-attention-deficithyperactivity-disorder-adhd" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77892.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">290</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">946</span> Static Eccentricity Fault Diagnosis in Synchronous Reluctance Motor and 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=M.%20Naeimi">M.

The motor vehicle market is growing tremendously particularly for the motorcycle. The growth of motorcycles ownership was 15 % annually from 2002 to 2012. It is predicted that the number of motorcycles still continue to grow in the future. The increase of motor vehicle has led to the creation of serious urban problems and Indonesian economy structure. Today, Indonesia's cities are well known as the jungle of motorcycle world. The volume of motor vehicle traffic in Indonesia cities is astounding, which more than 55% of motorised transport is on motorcycle and car. The reason it happens is due lack and inconvenient of the public transportation in Indonesia. Motor vehicle ownership by individual households tends to rising rapidly. Indonesian government still does not have a clear direction how to face this phenomenon. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Indonesian%20economy" title="Indonesian economy">Indonesian economy</a>, <a href="https://publications.waset.org/abstracts/search?q=inconvenient%20public%20transportation" title=" inconvenient public transportation"> inconvenient public transportation</a>, <a href="https://publications.waset.org/abstracts/search?q=motor%20vehicle%20growth" title=" motor vehicle growth"> motor vehicle growth</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20problems" title=" urban problems"> urban problems</a> </p> <a href="https://publications.waset.org/abstracts/25548/infrastructure-problems-in-indonesia-the-uncontrolled-increase-of-motor-vehicle-usage-in-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25548.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">438</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">944</span> Optimization of High Flux Density Design for Permanent Magnet Motor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dong-Woo%20Kang">Dong-Woo Kang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents an optimal magnet shape of a spoke-shaped interior permanent magnet synchronous motor by using ferrite magnets. 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 armature winding consists of several independent multiphase windings that have different rating rotate speed and power.

Performance of novel motor structure varies with winding match. In order to find optimum control strategy, motor torque character, efficiency performance and fault tolerance ability under different operation mode are analyzed in this paper, and torque distribution strategy for efficiency optimization is proposed. Simulation analyze is taken and the result shows that proposed structure has the same efficiency on heavy load and higher efficiency on light load operation points, which expands high efficiency area of motor and cruise range of vehicle.

The methodology relies on synergic model of noise generation as a function of time. The arbitrary number of motor vehicle noise sources act in concert yielding the generation of the overall noise level of motor vehicle thereafter. The number of noise sources participating in the overall noise level of motor vehicle is subjected to the constraint of the calculation of the acoustic potential of each noise source under consideration. It is the prerequisite condition for the calculation of the acoustic potential of the whole vehicle. The recast form of pertinent set of equations describing the synergic model is laid down and solved by dint of Gauss method.

A new optimization approach is proposed. This unique approach transforms automotive customer requirements into an optimization problem, based on sound knowledge of a SRM theory. The approach combines an analytical and a finite element analysis of the motor to quantify static nonlinear and dynamic performance parameters, as phase currents and motor torque maps, an output power and power losses in order to find the optimal motor as close to the reality as possible, within reasonable time. The new approach yields the optimal motor which is competitive with other types of already proposed motors for automotive applications. This distinctive approach can also be used to optimize other types of electrical motors, when parts specifically related to the SRM are adjusted accordingly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=automotive" title="automotive">automotive</a>, <a href="https://publications.waset.org/abstracts/search?q=drive%20system" title=" drive system"> drive system</a>, <a href="https://publications.waset.org/abstracts/search?q=electric%20car" title=" electric car"> electric car</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=hybrid%20car" title=" hybrid car"> hybrid car</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=switched%20reluctance%20motor" title=" switched reluctance motor"> switched reluctance motor</a> </p> <a href="https://publications.waset.org/abstracts/13141/optimization-of-switched-reluctance-motor-for-drive-system-in-automotive-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13141.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">521</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">938</span> Using of Particle Swarm Optimization for Loss Minimization of Vector-Controlled Induction Motors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V.%20Rashtchi">V.

Among the many loss minimization algorithms (LMAs) for an induction motor, a particle swarm optimization (PSO) has the advantages of fast response and high accuracy. However, the performance of the PSO and other optimization algorithms depend on the accuracy of the modeling of the motor drive and losses. In the development of the loss model, there is always a trade off between accuracy and complexity. This paper presents a new online optimization to determine an optimum flux level for the efficiency optimization of the vector-controlled induction motor drive. An induction motor (IM) model in d-q coordinates is referenced to the rotor magnetizing current. This transformation results in no leakage inductance on the rotor side, thus the decomposition into d-q components in the steady-state motor model can be utilized in deriving the motor loss model. The suggested algorithm is simple for implementation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=induction%20machine" title="induction machine">induction machine</a>, <a href="https://publications.waset.org/abstracts/search?q=loss%20minimization" title=" loss minimization"> loss minimization</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetizing%20current" title=" magnetizing current"> magnetizing current</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20swarm%20optimization" title=" particle swarm optimization"> particle swarm optimization</a> </p> <a href="https://publications.waset.org/abstracts/15437/using-of-particle-swarm-optimization-for-loss-minimization-of-vector-controlled-induction-motors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15437.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">633</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">937</span> Variable Frequency Converter Fed Induction Motors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdulatif%20Abdulsalam%20Mohamed%20Shaban">Abdulatif Abdulsalam Mohamed Shaban</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A.C motors, in general, have superior performance characteristics to their d.c. counterparts.

Thermal network modelling fairly predicts the temperature of various components inside the large-scale AC motor.

The neural control scheme consists of two parts. One is the neural estimator which is used to estimate the motor speed.

ANNs are the standard three layers feed-forward neural network with sigmoid activation functions in the input and hidden layers and purelin in the output layer.

Most of these children have difficulty with fine motor skills which typically struggle with handwriting and fine activities in their routine life such as getting dressed and controlled use of the everyday tool. Because fine motor activities encompass so many routine functions, a fine motor delay can have a measurable negative impact on a person's ability to handle daily practical tasks. This project proposed a simple fine motor exercise aid plus the game (exergame) for autistic children who discover from fine motor difficulties. The proposed exergame will be blinking randomly and user needs to bend their finger accordingly. It will notify the user, whether they bend the right finger or not. The system is realized using Arduino, which is programmed to control all the operated circuit. The feasibility studies with six autistic children were conducted and found the child interested in using exergame and could quickly get used to it. This study provides important guidance for future investigations of the exergame potential for accessing and improving fine motor skill among autistic children. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autism%20children" title="autism children">autism children</a>, <a href="https://publications.waset.org/abstracts/search?q=Arduino%20project" title=" Arduino project"> Arduino project</a>, <a href="https://publications.waset.org/abstracts/search?q=fine%20motor%20skill" title=" fine motor skill"> fine motor skill</a>, <a href="https://publications.waset.org/abstracts/search?q=finger%20exergame" title=" finger exergame"> finger exergame</a> </p> <a href="https://publications.waset.org/abstracts/109405/fingers-exergames-to-improve-fine-motor-skill-in-autistic-children" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109405.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">150</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">933</span> Optimum Design of Photovoltaic Water Pumping System Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sarah%20Abdourraziq">Sarah Abdourraziq</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachid%20El%20Bachtiri"> Rachid El Bachtiri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The solar power source for pumping water is one of the most promising areas in photovoltaic applications.

The contribution of external load torque and friction torque is monitored. The switching function technique is adopted for the current control of the embedded three phase inverter that drives the brushless DC motor.In switching functions the power conversions circuits can be modeled according to their functions rather than circuit topologies. Therefore, it can achieve simplification of the overall power conversion functions. The trapezoidal type (back emf) is used in the model as ithas lower switching loss compared with sinusoidal type (back emf). Results show reliable time analysis for speed, torque, phase and line voltages and currents and the effect of current commutation is clearly observed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BLDC%20motor" title="BLDC motor">BLDC motor</a>, <a href="https://publications.waset.org/abstracts/search?q=brushless%20dc%20motors" title=" brushless dc motors"> brushless dc motors</a>, <a href="https://publications.waset.org/abstracts/search?q=pwm%20inverter" title=" pwm inverter"> pwm inverter</a>, <a href="https://publications.waset.org/abstracts/search?q=DC%20motor%20control" title=" DC motor control"> DC motor control</a>, <a href="https://publications.waset.org/abstracts/search?q=trapezoidal%20back%20emf" title=" trapezoidal back emf"> trapezoidal back emf</a>, <a href="https://publications.waset.org/abstracts/search?q=ripple%20torque%20in%20brushless%20DC%20motor" title=" ripple torque in brushless DC motor"> ripple torque in brushless DC motor</a> </p> <a href="https://publications.waset.org/abstracts/22803/analysis-of-brushless-dc-motor-with-trapezoidal-back-emf-using-matlab" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22803.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">598</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">930</span> Modern Pedagogy Techniques for DC Motor Speed Control</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rajesh%20Kumar">Rajesh Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Roopali%20Dogra"> Roopali Dogra</a>, <a href="https://publications.waset.org/abstracts/search?q=Puneet%20Aggarwal"> Puneet Aggarwal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Based on a survey conducted for second and third year students of the electrical engineering department at Maharishi Markandeshwar University, India, it was found that around 92% of students felt that it would be better to introduce a virtual environment for laboratory experiments.
