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...

In today's life, the use of synchronous belts is becoming increasingly common, and its shadow can be found in large machinery such as machine tools, cars, small printers, copiers, and other small household appliances. The synchronous belt itself does not have accuracy, but its accuracy can be determined by whether there is a load when using the con...

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 ...

There are various forms of gear failure, among which the more common crack failure is a more serious form of failure. If the crack further expands, it may lead to fatigue fracture of the gear teeth, and even cause complete failure of the entire gear.Therefore, analyzing the fault mechanism of cracks and finding an effective method for diagnosing c...
