Within the Institute’s testing facilities, all electric machines from low power applications to modern traction drives can be characterized. Thanks to the 35 individual test benches, even complex test setups can be operated in parallel. Electrical power can be supplied at typical AC voltage levels (400 V / 690 V 3 phases) or at variable DC voltage levels up to 800 V. A central water-cooling system and different conditioning devices to control coolant flowrates and temperatures during the tests can be used. With our extensive measurement equipment, all relevant electrical, mechanical and thermal quantities can be recorded. Additionally, sound measurements of electric machines with suppressed ambient noise can be performed in the IEM AcousticLab.
In addition, the characterization of materials used in electric machines is vital for our research work. For that reason, two dedicated material research laboratories are operated at our institute: The MagLab for characterization of magnetic materials and the IsoLab to investigate insulation systems.
