AC Motor Designs

In module 1 you will learn principles of operation of AC induction motors, both single and 3-phase types. You well then learn how to interpret data from torque speed curves, and how to optimize data in these curves based on electrical resistance, inductance, and capacitance. Then you will learn about different types of single phase motors, featuring a video analysis of a split phase motor used in a clothing dryer. You will also learn about typical applications for single phase motors, which will assist you in picking the right one for an application. ...

DC Motor Control and Stepper Motors

In module 4 you will start off with another lab exercise, this time gaining hands-on experience with DC motor control. The we will illustrate a simplified stepper motor drive, so you will understand the basic principles involved in stepper motor control. Next, you will do a deep dive into stepper motor specs, operation and commercial driver chips and packages. You will then do another lab exercise, this time on actuating a rotary sensor. We end the module with a comparison of DC vs. AC motors, so you take away a core understanding of their pros and cons. ...
