EE Classroom on Motor Control</strong></span></p><br><p class="x_4886f134 x_3b27255f"><span class="x_7b2817bf">Electric motors — small and large — are so ubiquitous that they don’t always command the most attention. And yet, they are at the heart of end products in wide-ranging applications. Most motors in use today fall into alternating current (AC), brushed direct current (DC), and electronically commutated motors and also include steppers, brushless, synchronous, and induction.</span></p><p class="x_4886f134 x_3b27255f"><span class="x_7b2817bf"><br></span></p><p class="x_4886f134 x_3b27255f"><span class="x_7b2817bf">Here you will find resources on the basics of rotary encoders (optical and magnetic), and field-oriented motor control (FOC), which has progressed with improving and more sophisticated IC technology. A two-part webinar on advanced motor control technologies moves you further along your path of understanding beyond the basics, and testing tips for key motor control capabilities to help keep your designs in check. Then step into our Engineers Garage library with a couple of projects to do in your own garage. And the associated reference designs can help give your motor control application a kick-start.</span></p><p class="x_4886f134 x_3b27255f"><span class="x_7b2817bf"><br></span></p><p class="x_4886f134 x_3b27255f"><span class="x_7b2817bf">These resources are all designed to give you a better understanding of the advantages and disadvantages of motors, their various implementations, and key consideration when implementing a motor control application. </span></p> </div> </div> <div class="widget item-absolute headline " id="element-465" data-at="headline"> <div class="contents"> <h3>
