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 learned 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
