About the program
The seminar and its companion manual have been developed by Austin Bonnett, EASA's education and technology consultant, in collaboration with EASA's Technical Support Specialists and members of EASA's Technical Education Committee.

While the course covers horizontal and vertical squirrel-cage induction motors in the 300 to 5,000 horsepower range, low and medium voltage, most of the principles covered apply to other sizes as well. This seminar focuses primarily on NEMA motors.

Seminar highlights include:

• Motor theory
• Applications
• Safety considerations
• Root cause failure analysis overview
• Test and inspection procedures
• Starting methods and connections
• Accessories
• Stator construction and design
• Rotor construction and design
• Bearing types and lubrication systems
• Shaft construction
• Motor geometry and alignment
• Vibration and noise
• Cleaning, reconditioning, storage

Seminar Content
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 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 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
• Winding failures
• Rotor failures
• Shaft failures
• Mechanical failures
• DC motor failures
• Accessory failures
• Case studies

Important
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.

What To Bring
Instructional items will be provided. You should need only note-taking materials.
