Variable frequency motor refers to the general term for motors driven by frequency converters. Variable frequency speed regulation is currently replacing traditional mechanical speed regulation and DC speed regulation schemes with fast speed due to its advantages such as high efficiency, wide speed regulation range, high accuracy, smooth speed regu...

I am currently working on a design for fault diagnosis of three-phase asynchronous motors. The general idea is to build a model, obtain normal and fault signals, and finally use wavelet transform spectrum analysis. However, it is currently unclear how to model, what model is appropriate, and which parameters can be changed to achieve the correspond...

Many people say that under a certain voltage, the torque and current of a certain motor are directly proportional, and the speed and current are inversely proportional (also inversely proportional to the torque). Are these correct?

Asynchronous motors only have no back electromotive force when no voltage is applied to the stator winding. If voltage is applied to the stator, an air gap magnetic field will be established. When the rotor rotates, it will induce rotor current, which in turn generates rotor magnetic field. The rotor magnetic field affects the air gap magnetic fiel...

The out of step phenomenon of synchronous motors refers to the phenomenon that during synchronous operation, due to certain interference, the motor speed cannot be stable at the rated speed, and fluctuates within a certain range around the rated speed.This kind of fluctuation is called stepping out.The main reasons for synchronous motor stepping ...

A three-phase asynchronous motor is a type of motor that relies on the simultaneous connection of a 380V three-phase AC power supply. Due to the fact that the rotating magnetic field of the rotor and stator of the three-phase asynchronous motor rotates in the same direction but at different speeds, there is a slip rate, so it is called a three-phas...
