Our load testing facility for electric motors and generators At our modern testing facility in Osnabrück, we offer you the opportunity to test your electric motors and generators and have them certified by a wide range of classification societies.

Our three test stations can handle tests from 60 kW to 2100 kW. Each test station has a water connection for testing water-cooled machines. All test stations are equipped with state-of-the-art electronic and mechanical measurement technology. In addition, we can perform motor tests at ambient temperatures of up to 50°C.

The main applications are energy efficiency tests to determine efficiency classes IE1 to IE4, type tests, and routine tests of both squirrel cage motors operated on frequency converters or mains power and slip ring motors. However, we can also implement any kind of special request for you competently and at short notice.
