As a part of motor magnetic circuit and embedded stator winding. The stator core is formed by laminating silicon steel sheets with a thickness of 0.5 mm, and both sides of the brick-shaped steel sheets are coated with insulating paint to insulate the steel sheets from each other, so as to reduce the core loss caused by the rotating magnetic field in the stator core. The inner circle of the stator core is stamped with several identical slots for embedding the stator winding.

Second, the role of AC motor rotor is:

The rotor is a part of the magnetic circuit of the motor. Together with the stator core and air gap, it forms the whole magnetic circuit of the motor. Generally, 0.5mm thick silicon steel sheets are stacked in the rotor core. Most of the rotor cores of small and medium-sized AC motors are directly mounted on the motor shaft. The rotor core of a large AC motor is installed on a rotating bracket which is sleeved on the rotating shaft.
