Induction motors are widely used in the automotive industry. In order to increase the passenger’s comfort, motor designers try to develop new solutions to reduce the noise at its origin, on the electromagnetic side. Damper winding can be a solution to improve emitted vibration and noise. In this presentation, LSEE shows interesting modelling method to evaluate the impact of damper windings on the vibro-acoustic behavior of the motor considering PWM, and compares it with measurements.
