Electrical 2: Motors: Theory and Application

4.3 3 Reviews SKU: AEEMT01CENDuration: 120 Minutes

This course is designed to familiarize participants with the operation and use of various types of electric motors. After completing this course, participants should be able to describe the basic construction and operation of direct current (DC) motors, alternating current (AC) induction motors, and AC synchronous motors. They should also be able to explain how motor speed can be controlled and how motors and motor circuits can be protected from damage, and they should be able to interpret the information on a motor nameplate.
