Three-phase asynchronous motor: What is speed regulation motor? The speed regulating motor is a kind of motor that changes the speed of the motor by changing the series, voltage, current, frequency, etc., so that the motor can achieve higher performance. Speed regulating motor has been widely used in steel, power station, cable, chemical industry, petroleum, water mud, textile, printing dyeing, paper making, machinery other industrial sectors for constant torque decreasing torque of the load mechanical stepless speed regulation, especially suitable for the flow of large changes in the pump fan load supporting use, can obtain good energy saving effect.

Speed control motor electromagnetic speed control motor frequency conversion speed control motor, following the small series to see their differences.

The difference between frequency conversion governor electromagnetic governor mainly lies in the different control objects control methods. Variable frequency governor achieves the purpose of motor speed regulation by changing the frequency of the working power supply of the motor. The object controlled by the electromagnetic governor is the slip clutch of the electromagnetic speed-regulating motor. By changing the excitation current of the slip clutch, the slip (slip) rate of the slip clutch is changed to achieve the purpose of speed regulation.

Variable frequency speed regulation motor is to change the original power frequency of 50HZ to 0.2-400HZ through the frequency converter, the reason is to change the frequency to change the speed of the motor; Electromagnetic speed regulation motor has a set of independent electromagnetic slip speed regulation device, the speed of the motor itself does change, electromagnetic slip has 5 lines, two are 220 volts power supply, 3 are the governor to the signal feedback speed signal, by changing the voltage of the slip to control the slip the difference, thus changing the output speed, electromagnetic speed regulation is equivalent to a manual transmission, Because the motor speed is constant, the torque is high.

Three-phase asynchronous motor: Different motors have different uses, Xiaobian suggests to do a general understanding before buying, in order to choose a better performance of the equipment.
