It is a device used to realize the conversion of electrical energy into mechanical energy and mechanical energy into electrical energy. The iron core of the motor rotor is made of multiple rotor punchings stacked and pressed together. A shaft is connected in the middle of the rotor to output the mechanical energy through the shaft. The permanent magnet of the built-in rotor structure is located inside the rotor. There is a pole shoe made of ferromagnetic material (usually laminated silicon steel sheets) between the outer surface of the permanent magnet and the inner circle of the stator core, which helps to use the magnetic resistance torque to improve the overload capacity and power density of the motor, and is easy to expand the speed with weak magnetic field. When processing the rotor punching, punching equipment is generally required.

[0003] However, the punching mechanism on the existing punching equipment for processing generator rotor punching sheets is generally fixedly arranged. When holes of different sizes need to be punched, it is inconvenient to replace the punching mechanisms of different sizes because the punching mechanisms are inconvenient to disassemble.
