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 seventh lesson in the AC/DC Motor Theory Course. The lesson introduces participants to DC motor theory.

Module Objectives

• Explain the effect of armature current on the main flux field and motor action.
• Explain the process of commutation and how it maintains direct current in a DC motor.
• Describe how the number of windings and commutator segments effects torque and mechanical power of a DC motor.
