Electric Motor Test Bench
The laboratory for electric machines of the Center for Mobile Propulsion allows testing of various electric motors and generators e.g. for Range Extender applications. The test bench is equipped with a dyno, an electric motor test device and a flexible IPU (Inverter Power Unit).
An industrial IPU can be used for characterization of electric machines under steady state conditions. The temperature of the test object can be varied in a wide range by external conditioning of the coolant water.
In such tests the losses and the thermal behavior of electric motors can be analyzed in detail. Future research work will include the test of advanced inverter control algorithms.
