Background technique

Three-phase asynchronous motor is a kind of induction motor, which is a type of motor powered by 380V three-phase AC current (phase difference 120 degrees) at the same time. The rotational speed of the motor turns into rotation, and there is a slip rate, so it is called a three-phase asynchronous motor. The rotational speed of the rotor of the three-phase asynchronous motor is lower than the rotational 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. The interaction generates electromagnetic torque and realizes energy conversion.

At present, in the process of using the existing three-phase asynchronous variable frequency speed regulation motor, when the rotation frequency of the motor shaft decreases, this may cause the speed of the fan to slow down, and the heat dissipation effect will also deteriorate. The motor only relies on the rotation of the fan for heat dissipation, and the heat dissipation capacity is poor, and the heat cannot be sent out in time, thus affecting the working efficiency of the motor. If the heat dissipation effect is poor for a long time, the overall life of the motor will be shortened. Therefore, a high-efficiency three-phase asynchronous variable frequency speed regulating motor is proposed to solve the above problems.
