[0002] The motor stator is an important component of reduction motors such as generator reduction motors and starters. The stator is an important part of the motor. The stator consists of three parts: stator core, stator winding and frame. The main function of the stator is to generate a rotating magnetic field, and the main function of the rotor is to be cut by magnetic lines of force in the rotating magnetic field to generate (output) current. The stator winding can be divided into two types: salient pole type and sine pole type according to the relationship between the number of magnetic poles of the motor and the actual number of magnetic poles formed by the winding distribution. In the process of producing reduction motor stators, it is often necessary to use winding repair equipment for staff to place and assemble substandard reduction motor stators to ensure that the electronic stator can meet the qualified standards under the operation of the staff.

[0003] The inventors have discovered in their daily work that, in the process of repairing motor stators with the help of winding repair devices, most of the existing winding repair devices on the market only rely on shaft rollers to support the position of the motor stator when in use. Since the shaft rollers are driven by electrical equipment, the motor stator will rotate under the action of the shaft rollers when the device is working, and due to the simple support structure, the motor stator will shift during rotation. After the shift, its position needs to be manually adjusted, resulting in reduced processing efficiency, increased processing time of a single workpiece, and further increased energy consumption during processing of a single workpiece.
