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.
