Title: Distinguish between various AC motors and DC motors.
Course: Mechatronics II (13901-II) > Section: Understanding Mechanical Components in a Mechanical System

Distinction should include measuring and comparing behaviors of various motors such as single-phase, three-phase, variable-frequency-drive (VFD), stepper, and servos.

Process/Skill Questions:

- What types of motors use brushes? What are the advantages of brushless motors?
- How does a variable frequency drive enhance the operation of AC motors?
- How does a microstepper driver enhance the operation of a stepper motor?
- What are the differences among unipolar, bipolar, and universal stepper motors?
- What does the term servo imply?
