Electric motors and powertrains present new challenges for durability testing and understanding the physics of failure. For example, traditional acceleration methods of running at an increased temperature are often impossible because the motor and inverter cannot survive them.

Motors also introduce new failure modes including demagnetization, bearing currents, and turn-to-turn shorts, which result in mechanical failure modes but can be more easily monitored and understood through electrical measurements.

In this free webinar, HBK’s Mitch Marks discusses the failure modes of electric motors and explains the benefits of measuring electrical values for durability testing.

Key topics and takeaways:

• Understand the common motor failure modes
• Learn how to measure motor failures
• Gain insight into examples of motor failures
