Based on the electromagnetic design scheme of high-speed permanent magnet motor for electrical tools, the project team designed and tested a set of high-speed motor drive system test platform, which can be loaded with the eddy current dynamometer to meet the needs of different load conditions. And we used the torque sensor to directly measure the motor outputs torque which was displayed on the torque indicator. The set of high-speed motor test platform software and hardware were independently designed by the project team developed to meet the maximum 25000rpm and 2kW following single-phase or three-phase high-speed motor load test.
