Abstract
The utility model discloses an asynchronous motor. The asynchronous motor comprises a casing, an armature, a stator, a rotor sleeved inside the stator and a rotating shaft arranged inside the rotor in a penetrating way. The two sides of the rotating shaft are provided with electromagnets. Electromagnet coils are wound on the electromagnets. The armature is located right above the electromagnets. Meanwhile, the armature can be sleeved on the rotating shaft in an axially moving way after the electromagnets are electrified. A friction plate is arranged on the armature and located between the rotor and the armature. The lower end of the rotating shaft is provided with an elastic element. The armature can be sleeved on the rotating shaft in a way of axially moving by compressing the elastic element. When the asynchronous motor is power on, the electromagnet coils are electrified and the armature is absorbed by the electromagnets. The friction plate is disengaged. The normal rotation of the motor is ensured. After the asynchronous motor is power off, the acting force of the armature and the friction plate is born by the elastic element. The motor generates self-locking force. The asynchronous motor with a simple structure is suitable for wide application.
