Industrial Motor Controls: Operation, Troubleshooting & Maintenance

Details

Programme Introduction

This course is designed to help maintenance people identify what the real issue is when a motor burns out and how to prevent it from happening again. It involves understanding the control of the motor as well as the motor itself.

Programme Objectives:

Upon completion of this course, students will learn to:

Identify the different types of motors and their appropriate applications

Test for & troubleshoot motor problems

Properly select and replace a motor

Keep a motor properly maintained

Identify & understand symbols used in common control circuit drawings

Use a logical, systematic approach to troubleshooting

Find and fix common control circuit problems
