In the daily machinery production industry, speed regulation is also widely used; The speed regulation we commonly use is to change the motor speed by changing the number of magnetic poles, current, voltage, frequency, etcThree-phase asynchronous motorSuch as products to achieve a higher performance, then Senli motor Xiaobian will first briefly introduce the speed regulation mode of changing the number of poles.

       Three-phase asynchronous motorThe rotation speed formula isn=60f/pFrom the formula, change the number of polesPCan achieve the purpose of changing the speed. This speed regulation method is to change the stator pole number of the squirrel cage induction motor by changing the wiring mode of the stator winding, so as to achieve the purpose of speed regulation, mainly has the following characteristics:

       It has hard mechanical characteristics, good stability, no slip loss, and high efficiency. The wiring mode is simple and the control is convenient. It belongs to the stage speed regulation, the stage difference is large, can not get smooth speed regulation; It can be used with voltage regulation and electromagnetic slip clutch to obtain smooth speed regulation characteristics with high efficiency.

       Changing the number of poles speed regulation method is suitable for production machinery that does not need to be stepless speed regulation, such as some fans, pumps and so on.
