Course Description

This course will provide the student with a basic understanding of the operation and characteristics of various electric generators, alternators, motors, drive-train components, electronic motor drives, and simple motion control systems. Students will install and operate various kinds of motors, testing them for speed, torque, and efficiency. Basic motor-circuit troubleshooting will be emphasized. This course also explores pulse-width modulated motor-speed control, stepper motors, and servo motors and control systems. Motor and generator related projects may be employed as time permits.
