MC-100COURSE DESCRIPTION

This 32-hour, 4 day training program is designed to provide maintenance electricians with a thorough understanding of AC and DC motor construction, operation and variable speed control. Hands-on lab exercises are used throughout the training program to simulate actual plant conditions. Course hardware will include Variable Frequency AC and DC Motor Drive Workstations, Circuit Test Workstations, Oscilloscopes and Multimeter test equipment. Hands-on labs will explain operation and troubleshooting of diodes, transformers, SCR’s, transistors and other electrical control devices.
