Electric Motors & Control Circuits On-Site Training

This on-site training class is also available as Public Schedule Seminar.

A practical course for maintenance personnel working in industrial plants, public facilities and commercial buildings! 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.
