[0002] The stator and rotor are important components of an electric motor. In the existing market, the stator and rotor are respectively composed of multiple thin iron cores stacked together. Due to process requirements, some stators of the same model can be configured with different styles of rotors. The shapes and dimensions of different styles of rotors, such as the shape of the rotor groove punch, the number of magnet slots punches, and the number of center hole punches, are all different. According to the traditional mold production method, a set of stator molds is configured with a set of rotor molds in a fixed manner. In this case, the interchangeability is poor, and three different sets of rotor molds need to be matched with three sets of stator molds, resulting in an increase in production costs.
