Motors and Motor Control Systems

Course Description

This course will review basic motor theory and operation of all types of AC and DC motors.  We will review the electrical characteristics and connections of motors. We will review principles of single phase AC motors and three phase AC motors. The operation of the types of AC motors, starting and running. We will review DC motors series, shunt and brushless motors. The course will cover NEMA design types, motor enclosures, frame, insulation types, and lock rotor codes. We will review the NEC application of motors, and motor controllers in Article 430.  Understanding the function of control equipment of motor starters, contactors, relays, timing circuits, voltage monitors, phase monitors and setting of these devices.
