Description

Technical Field

[0001] The utility model relates to the technical field of three-phase asynchronous motors, in particular to a three-phase asynchronous motor for a fan. Background Art

[0002] The three-phase asynchronous motor is a type of induction motor, which is powered by 380V three-phase AC current (phase difference of 120 degrees) at the same time. 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 winding and the magnetic field, and interacts with the magnetic field to generate electromagnetic torque to achieve energy conversion.

[0003] The three-phase asynchronous motor in the prior art can drive the fan when in use to complete the circulation of gas, but the temperature of the motor is high when in use and the heat generated inside needs to be dissipated in time. The traditional method uses the fan blades at the rear end for heat dissipation, but this heat dissipation method inevitably cools down the high temperature in time, which is inconvenient to use and will cause high-temperature damage to the motor.
