Part II
Motors and Motor Control Systems
Course Description
The course will review motor failure modes and measurements on motors. The course will cover how different motor react to voltage changes such as reduced voltage and increase voltage above name plate. Voltage balance and motor derating will be discussed and how to best derate motors. 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.
