This module will focus on the principles of DC motors and the various types used in industry. The student will learn the fundamentals of speed control including dynamic and regenerative braking. Servo-, Stepper- and Brushless DC motors are discussed as well as basic dynamo configurations. This module also introduces the student to electronic speed control of DC motors.
Learning Outcomes:
Upon completion of this module the student will be able to:
- Explain the purpose of a commutator in DC motors.
