Technical Field

[0002] An asynchronous motor, also known as an induction motor, is an AC motor that converts electromechanical energy into mechanical energy by generating electromagnetic torque through the interaction of the rotating magnetic field in the air gap and the induced current in the rotor winding. Existing high-slip asynchronous motors with high starting torque suffer from poor drive shaft stability during startup, which can easily cause the drive shaft to vibrate or break.

[0003] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a high-slip asynchronous motor with large starting torque is proposed. Utility Model Content
