The "pole number" we usually say refers to the number of magnetic poles of the motor stator field, and the different connections of the stator windings can form different poles of the stator field. SelectThree-phase asynchronous motorThe number of poles is determined by the speed required by the load, and the number of poles directly affects the speed of the motor.
We use the speed=60f/pIn terms of this formula, that is 60 Times the motor frequency, divided by the number of motor poles. According to the formula, it is not difficult to see that the more series, the lower the speed, the fewer poles, the higher the speed.
Three-phase ac motorEach set of coils will produce N,S The number of magnetic poles contained in each phase of each motor is the number of poles. Since the magnetic poles appear in pairs, the motor has 2,4,6,8The best wait. In China, the power frequency is 50 Hertz,2 Polar synchronous speed is 3000r/min,4 Polar synchronous speed is 1500r/min,6 Polar synchronous speed is 1000r/min,8 Polar synchronous speed is 750r/min.
The winding one to go to form a loop, that is, the number of magnetic poles, is in pairs, the pole is the meaning of the magnetic pole, these windings when the current will produce a magnetic field, the corresponding magnetic pole. The current of the motor is only related to the voltage and power of the motor.
The two poles are called high-speed motors, the four poles are medium speed, the six poles are low speed, and the eight poles are greater than or equal to the ultra-low speed.
two-stage 2800-3000 turn / minutes
quadrupole 1400-1500 turn / minutes
Cet 6 900-1000 turn / minutes
Greater than or equal to eight poles is below 760 turn / Minutes.
