[0002] A motor (commonly known as a "motor") is an electromagnetic device that realizes the conversion or transmission of electrical energy based on the law of electromagnetic induction. It uses an energized coil (i.e., a stator winding) to generate a rotating magnetic field and acts on a rotor (such as a squirrel-cage closed aluminum frame) to form a magnetoelectric dynamic rotating torque.
[0003] After the production of the motor stator, it needs to be powered on for testing to detect whether there are defects in the stator coil and the PCB board. However, the stator and the rotor are separate and cannot directly install the rotor for verification. Since there is no bearing to fix the motor stator at this time, if it is forcibly powered on for testing, it will cause wear of the silicon steel sheets on the inner wall of the stator. Therefore, providing a motor stator detection device is a technical problem that needs to be urgently solved by those skilled in the art. Content of the Utility Model

A clamping cylinder is fixedly arranged on one side of the mounting cylinder, and the driving end of the clamping cylinder is fixedly installed with a chuck. By moving the chuck, the motor stator can be fixed in the placement groove.
