Factory acceptance testing of a dual-powertrain test stand for the customer Alber at imc

The E-motor test stand designed and built by imc for the company Alber is not a commonplace solution. Recently, the customers Mr. Bitzer and Mr. Kaiser came to Berlin for the final commissioning and acceptance inspection of their new test stand. The two powertrains, consisting of an asynchronous machine from AMK and a dual-range torque transducer from Burster, can simultaneously and independently provide loading and thus test the complete auxiliary drive of a wheelchair for its performance data. Alternatively, on bicycle motors, the drive side system (chainring, chain, sprocket) and the driven side (rolling resistance) can also be simulated. For realistic acceptance tests, the wind blowing on the motors can be simulated by two independent blowers. Fan control occurs through a preset volume flow rate or wind speed.
