[0002] The motor core is one of the core components of the motor. The core is usually made of high-purity silicon steel sheets, which are bonded together to form a stable structure. The function of the core is to provide stable support for the stator and rotor. In the motor, the magnetic field generated by the stator and rotor requires a stable medium to carry and transfer. The core is this medium. The core can transmit the magnetic field well, reduce magnetic flux leakage, and improve the efficiency of the motor. In the production and assembly of the motor, a pressing device is often required to press the core into the motor body.
