Electric Motor Dynamometer Testing Services Case Study

A supplier to the heavy duty industry approached Millbrook for high-speed electric motor testing on a dynamometer in order to characterize the design requirements against target torque, speed and power values.

Millbrook provided efficiency measurements from the DC-BUS to mechanical output of the machine, thermal characterization and heat balance and UN/ECE Regulation 85 power measurements with witnessed sign off.

The customer also required testing of a new power electronics and motor pairing; the inverter and motor system were baselined for future development. Millbrook conducted the tests against UN/ECE Regulation 85 and the customer’s power density mapping requirements. It issued a report detailing the efficiency and peak performance of the system.
