This is lab 1 of 4 in the course, Fundamentals of Mechatronic Actuators.


After completing this lab, students will be able to:
  1. Understand the electromagnetic principlals of a DC motor.
  2. Describe the mechanical design and functionality of brushed DC motors.
  3. Describe the mechanical design and funcitonality of brushless DC motors.
  4. Design a control signal to produce a desired speed output for both types of DC motor.
  5. Contrast the brushed and brushless motors in terms of major design criteria.
  6. Evaluate the suitability of one or the other DC motor design, given example applications.
