When we select motor products, the speed is an important reference factor, and the speed is determined by the number of poles of the motor. The number of poles is usually the synchronous speed of the motor, but the three-phase asynchronous motor will have a certain difference because of the slip rate. Here is a simple understanding of Senli Motor.

       We'll2The level is called a level pair, which indicates that a magnetic field has one eachNLevel and oneSThe number of poles determines the synchronous speed of the motor, and the synchronous speed per minute is equal to the frequency times60The number of depolarizations. Since the magnetic poles appear in pairs, the motor has2,4,6,8,10...Very different.

       1Opposite-pole, two-stage motor∶Synchronous speed3000Turn, asynchronous speed2880Turn around.

       2The magnetic pole is a four-stage motor∶Synchronous speed1500Turn, asynchronous speed1450Turn around.

       3The magnetic pole is six level motor∶Synchronous speed1000Turn, asynchronous speed960Turn around.

       4The opposite pole is the eight-stage motor∶Synchronous speed750Turn, asynchronous speed730Turn around.

       For the same power, but different number of polesThree-phase asynchronous motorThe more the number of magnetic poles, the lower the speed, the larger the volume, but the larger the output torque; The fewer the number of magnetic poles, the higher the speed, the smaller the volume, but the output torque is also small.

       Three-phase asynchronous motor manufacturer reminderThe speed of AC motors (whether synchronous or asynchronous) is limited by the frequency of the power supply.
