[0002] The stator and rotor punching sheets of the motor are one of the core components of the motor. They play a key role in the operation of the motor. The manufacturing process of the stator and rotor punching sheets usually includes material preparation, mold design and manufacturing, material cutting, loading and stamping. The punching sheet stamping process uses stamping equipment to impact the metal material through the mold, causing it to undergo plastic deformation under the action of force to obtain the desired shape. After the motor stator and rotor punching sheets are punched, the positioning device is needed to position and polish the surface of the motor stator and rotor.
