What are the causes of overload of three-phase asynchronous motor?

Although the operation of three-phase asynchronous motor is generally stable and the accident rate is small, it does not mean that there is no fault. If the load it drives exceeds the rated power of the motor, the motor will be overloaded.

What is the method to reduce the vibration of three-phase asynchronous motor?

The vibration of asynchronous motor is the focus of motor structure design at present. It is composed of electromagnetic vibration, mechanical vibration and gas vibration. Electromagnetic vibration: the interaction of the magnetic field in the air gap of the motor generates electromagnetic force varying with time and space on the rotor and stator, causing the motor to vibrate.
