The speed of the shaded pole motor is divided into grades, and the speed of the speed is determined by the number of poles. Then let's understand what the pole number of the shaded pole motor is and how to divide it.

1. The “number of poles” of a three-phase asynchronous shaded pole motor is the number of magnetic poles of the specified sub-field. The stator windings are connected in different ways, which can form different pole numbers of the stator magnetic field. The number of poles of the shaded pole motor is determined by the speed required by the load. The pole number of the shaded pole motor directly affects the speed of the shaded pole motor.

2. The speed of the shaded pole motor = 60f/p, which is 60 times the frequency of the shaded pole motor divided by the number of poles of the shaded pole motor. According to the formula, it is not difficult to see that the more the series, the lower the speed, and the fewer the poles, the higher the speed.

3. Each group of coils of three-phase AC shaded pole motor will generate N and S magnetic poles. The number of poles in each phase of each shaded pole motor is the number of poles. Since the magnetic poles appear in pairs, the shaded pole motor has 2, 4, 6, and 8 poles. In China, the power frequency is 50 Hz, the 2-pole synchronous speed is 3000r/min, the 4-pole synchronous speed is 1500r/min, the 6-pole synchronous speed is 1000r/min, and the 8-pole synchronous speed is 750r/min. The windings come and go to form a loop, that is, the number of magnetic pole pairs, which appear in pairs. The poles mean magnetic poles. When these windings pass current, a magnetic field is generated, and correspondingly there will be magnetic poles. The current of the shaded pole motor is only related to the voltage and power of the shaded pole motor.
