The utility model discloses a tester for the starting torque of a permanent magnet motor, wherein a permanent magnet motor shaft is connected with one end of a force transferring lever by a flange plate, another end of the force transferring lever is fixed on a support provided with a pressure sensor, and the pressure sensor is connected with a data processor by a line. After the tester is installed, the permanent magnet motor is electrified at 5 seconds, the stalled permanent magnet motor generates a fluctuant rotating torque, the torque transfers a force onto the pressure sensor through the force transferring lever, the pressure sensor acquires a fluctuant pressure signal and transmits the signal to an signal amplifier, the signal is amplified and is transmitted to the data processor by means of analog-to-digital conversion, the data processor obtains the starting torque of the permanent magnet motor by means of analysis computation, and stores the starting torque, and a test result is displayed on a display screen or printed as required. The tester experimentally testes the starting torque of more than seventy permanent magnet motors, thereby being exact and stable in result.
