Electric motors of mild hybrid vehicles shall be tested under conditions as close to reality as possible. Besides different static and dynamic function tests, the 3-phase asynchronous motor, as well as the inverter, shall be cooled down to -20 °C and heated up to +70 °C afterwards. Thus, the demands on motors that can occur during operation of an electric / hybrid vehicle are simulated.
The test system is to be used in the analysis for persistent tests which are not possible in production due to short cycle times.
