──Nov 14 , 2021Relation between speed and pole number of three-phase asynchronous motor

       The speed of the three-phase asynchronous motor is related to the number of poles of the motor. In the case of constant output power, the more poles, the slower the speed. Here is the motor Xiaobian together to understand.

       The frequency of the three-phase alternating current we use is50Hz, therefore2Polar synchronous speed is3000r/min,4Polar synchronous speed is1500r/min,6Polar synchronous speed is1000r/min,8Polar synchronous speed is750r/min. These speeds are only the synchronous speed of various pole motors, rather than the actual speed.

Three-phase asynchronous motor manufacturers products

       For synchronous or asynchronous motors, the speed of the motor is related to the frequency of the power supply and the number of magnetic poles of the motor, the higher the frequency of the power supply and the fewer the number of magnetic poles, the higher the speed; towardsThree-phase asynchronous motorIt is also related to the current through the electric coil, the greater the current, the closer its speed is to the synchronous speed. There is also a class of motors (usually AC and DC motors), whose speed is independent of the frequency of the power supply, and only related to the size of the current through the coil.
