The test centre for electric motors offers the possibility to carry out extensive analyses of electric drives. The test bench includes all components that are 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 field of application ranges from efficiency measurements, load and demagnetisation tests to thermal validation and structure-borne noise measurements. In addition, measurements for ECE-R85 certification can be carried out for approval of the motors as drives in motor vehicles.
The planning and assembly of the test specimen are carried out by experienced, expert personnel. The tests are accompanied by a measurement engineer who operates and monitors the test bench.
