Electric Motor Maintenance

Course Overview

Electric motors are among the highest in reliability incident reports. For many companies, this

leads to a continual cycle of costly repairs and unplanned downtime factors that can hurt the

bottom line.

Since 40% to 70% of motor failures are related to bearings, its no surprise that high-quality

bearings are key for reliable motors. The right bearings alone wont deliver the results you

need. How parts are installed, lubricated, handled, stored, aligned, and maintained is equally

important

This training course will train students to disassemble, inspect, maintain, and troubleshoot AC

Induction motors including a practical motor overhaul.

Key Learning Outcomes

1. An effective implementation of electrical motormaintenance will translate into savings from

production availability, reduced equipment

repair costs and improved energy costs.

2. Students will have an appreciation and

understanding to perform optimal diagnoses

and repairs.

3. Students will learn the techniques and obtain

valuable information to detect motor problems

prior to failure, avoiding costly downtime.
