Electric Motor Testing - De-Energized

Course Details

Public Course
Electric Motor Testing (EMT)

Manufacturers of motor testing equipment all use similar methods of data collection for the analysis of motors and electric motor circuit faults offline. Their respective training courses are geared toward the operation of their particular equipment, with a great deal of time spent on software. The intent of The Snell Group's training course is to simplify the motor testing process by examining the individual tests utilized by today’s electric motor testing equipment.

To help the student understand the theory behind these individual tests, sample motors and motor components will be tested using specific test equipment designed to identify specific failure modes.  Correlation of the results of these individual tests will be made with the integrated and computer controlled equipment developed by today’s motor tester equipment manufacturers. This will provide the student with a sound theoretical foundation to safely and successfully analyze, troubleshoot and maintain motors and their circuits regardless of what equipment is utilized or eventually procured.

Course Overview:

  • Failure modes of motors and related circuitry
  • Theory to support motor testing
  • Motor theory
  • Construction of motors
  • Motor rewinds
  • Motor operation
  • Nameplate information
  • Standards and references that support motor testing 

Students learn the proper techniques to collect data and they will be able to tell the difference between good and bad data. You will be able to apply multiple types of test equipment and understand the data collected. Students will be able to relate the data to specific failure modes, which will allow you to isolate the source of the problem in the motor or motor circuit and determine the condition of the tested motor.

The course is open to everyone regardless of whether or not they own a motor testing unit. Attendees that do have equipment are encouraged to bring their systems.
