High-Speed motor test bench

Due to the high rotational speeds at comparatively low torque, conventional test benches are not suitable for the measurement of high-speed motors as a result of centrifugal forces and rotor natural resonance frequencies. Thus, a customized test bench has been designed to meet these requirements at rated range of up to 10kW shaft power, 3Nm torque and rotary speeds of up to 50.000 1/min. Measurement of both motors and generators is enabled through the unrestricted four-quadrant-operation. The application of a DSP-environment allows fully automated measuring of torque-speed-characteristics and simultaneous registration of electrical quantities.
