Entry-level 3-Phase Motors, Maintenance and Repair

This class will be interesting for entry-level personnel who are taking on any responsibilities involving electric motors.  You will get a visual image of why a motor shaft rotates and how fast it turns, compliments of Michael Faraday and Nicola Tesla.  We cover common motor terminology, plus industry standards and regulations.  Learn how the federal government now requires new motors to be very energy efficient.

What makes a repair good?  We discuss what a service center needs to do in order to maintain a motor’s reliability and its efficiency.  Simple motor testing will be covered, plus lubrication and maintenance tips.

Three-phase Motors and Variable Frequency Drives

This class covers the impacts that today’s variable frequency drives have on motor performance and life expectancy.  We explain why so many applications now have variable speed controls (pretty much the same reason cars have gas pedals).  What can you request in new motors and repaired motors that will allow them to run longer?

Henry Stimson will explain the role of shaft grounding as it pertains to the static and circulating shaft currents caused by today’s variable frequency drives.  His demonstration display will leave no doubt that shaft currents exist, and they aim to ruin your bearings!

John Bowlin will explain the role of power devices that condition power entering the variable frequency drive or leaving the drive.  He will answer why these devices might be added to a system, and the benefits that accrue from them.

The class is free.
Lunch is our treat!
