Technical Field

[0002] At present, permanent magnet synchronous motor is a synchronous motor that generates a synchronous rotating magnetic field by permanent magnet excitation. The permanent magnet acts as a rotor to generate a rotating magnetic field. The three-phase stator winding induces a three-phase symmetrical current through armature reaction under the action of the rotating magnetic field. The permanent magnet synchronous motor can install the motor as a whole on the axle to form an overall direct drive system, that is, one axle is a drive unit, eliminating a gearbox.

[0003] When the detection device of the permanent magnet synchronous motor is in use, the platform on which the motor is placed is not stable enough when adjusted up and down, and the synchronous motor being detected will vibrate on the test platform. There is no device for clamping and fixing the synchronous motor, which will cause the connection between the output shaft of the motor and the detection device to be not stable enough, affecting the detection result of the motor. In addition, there are many models and sizes of permanent magnet synchronous motors, which makes it inconvenient to quickly fix permanent magnet synchronous motors of different sizes, thereby affecting the working efficiency of the detection device.
