Our offer

The test centre for electric motors makes it possible to carry out extensive analyses of electric drives. The test stand includes all components necessary for a measurement. These include the load machine, a vibration-decoupled machine bed and measurement technology for recording mechanical and electrical measured variables. The range of applications extends from efficiency measurements and load and demagnetisation tests to thermal validation and structure-borne sound measurements. In addition, the measurements for an ECE-R85 certification can be carried out for an approval of the motors as a drive in motor vehicles. The planning and set-up of the test object is guaranteed by experienced expert personnel. The examinations are accompanied by a measurement engineer who operates and monitors the test bench (plant poster; PDF).
