Description

Technical Field

[0001] The utility model relates to the technical field of three-phase asynchronous motors, in particular to an ultra-high efficiency three-phase asynchronous motor with a heat dissipation bearing structure. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. They are mainly used in the output shaft position of motors.

[0003] The three-phase asynchronous motor is a type of induction motor. It is a type of motor that is powered by a 380V three-phase AC current. Since the rotor and stator rotating magnetic field of the three-phase asynchronous motor rotate in the same direction and at different speeds, there is a slip rate, so it is called a three-phase asynchronous motor. The speed of the rotor of the three-phase asynchronous motor is lower than the speed of the rotating magnetic field. The rotor winding generates electromotive force and current due to the relative motion between the rotor and the magnetic field, and interacts with the magnetic field to generate electromagnetic torque to achieve energy conversion.

[0004] However, when the existing three-phase asynchronous motor is working, the motor speed is high and the working time is long. The internal bearings work for a long time and the temperature is high, which can easily cause damage to the bearings and reduce the service life of the bearings. Therefore, the bearings need to be cooled.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
