[0002] Before a synchronous motor is produced, relevant tests need to be carried out on the motor before installation to facilitate subsequent debugging, which helps to improve the performance of the motor. When testing the electrical performance of the motor, the motor to be tested needs to be fixed on a test bench. The rotor of the motor to be tested is softly connected to the rotor of the eddy current brake through a coupling. When the motor to be tested and the eddy current brake are energized respectively, by measuring various electrical parameters, various performance parameters of the motor to be tested are calculated.
