Using Electrical Signals to Evaluate and Monitor Motor Durability

Electric motors and powertrain present new challenges for durability testing. Traditional acceleration methods of running at an increased temperature are often not possible because the motor and inverter cannot survive them. Motors also introduce new failure modes like demagnetization, delamination, and turn to turn shorts amongst others. These failures will result in mechanical failure modes, but can be more easily monitored and understood through electrical measurements.

This session will discuss the failure modes of electric motors, benefits of measuring electrical values for durability testing, and give real data from durability testing.
