The motor core is usually composed of a stator and a rotor. The stator is usually the non-rotating part, and the rotor is usually embedded in the inner position of the stator. In the production and processing of the motor core, the press is usually used for stamping when the silicon steel sheets are stacked and pre-pressed.
