Root Cause Failure Analysis, 2nd Edition

Course length: Two days
Available as a condensed course: Available in half day sessions (see list)
Maximum number of students: 30

Course description

One of the most important factors to consider when repairing motors is to understand why they failed. This seminar will focus on common as well as unusual types of failures broken down by components.

This seminar, updated in 2019, is intended for anyone interested in understanding motor failures, and those who want to serve customers by addressing the cause of failure rather than the symptom. An extensive 328-page resource manual includes hundreds of photos of a wide range of failures, with the likely causes listed, and a clear methodology for confirming the probable cause of each failure. 

Seminar highlights

  • Root cause methodology
  • Bearing failures
  • Stator failures
  • Shaft failures
  • Rotor failures
  • Mechanical failures
  • DC motor failures
  • Synchronous motor failures
  • Accessory failures
  • Case studies

To reap the full benefit of the Root Cause Failure Analysis seminar, attendees should have basic knowledge of electric motors either through experience or from attending EASA’s Principles of Medium & Large AC Motors seminar.

Instructor(s) available to teach the course: 

  • Tom Bishop, PE, EASA Senior Technical Support Specialist
  • Mike Howell, PE, EASA Technical Support Specialist
  • Chuck Yung, EASA Senior Technical Support Specialist
