Course Overview

The AC/DC Motor Theory course was specifically developed for electricians and electronic technicians as well as for the multi-craft training needs of process and manufacturing facilities. This course consists of 11 interactive, on-line lessons that address AC and DC motor theory.

Module Overview

This is the final lesson in the AC/DC Motor Theory Course. This lesson trains participants in starters, rotation direction, speed control, and drive controls of DC motors.

Module Objectives

• Explain why a reduced voltage starter is sometimes needed in a motor.
• Explain how a reduced voltage starter works.
• Explain what determines the direction of rotation of a DC motor.
• Explain how a reverse contactor works.
• Explain how to control the speed of a DC motor.
• Explain how a tapped resistor works.
• Explain a DC driveÕs control system and how it works.
