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.

Our commonly used speed regulating motor has three main speed regulating modes:

Electromagnetic speed regulation slip motor has a wide range of speed regulation, smooth speed regulation, large starting torque, small control power of good speed regulation characteristics, the controller tachometer generator speed test feedback components composed of automatic regulation system, with speed control control is simple reliable, mechanical characteristics of high hardness series of advantages. Therefore, it is widely used in printing presses staplers, wireless binding, high frequency drying coupling, chain boiler grate control.

Frequency conversion speed regulating motor is a general term for the motor driven by the frequency converter. Variable frequency speed regulating motor is referred to as variable frequency motor, which is a general term for the motor driven by the frequency converter. In fact, the motor designed for the frequency converter is a special motor for frequency conversion, the motor can achieve different speed torque under the drive of the frequency converter to adapt to the demand change of the load.

Variable stage speed regulation is to change the logarithm of the motor's magnetic stage by changing the connection mode of the stator winding of the motor, so that the synchronous speed can be changed successively the motor speed can be adjusted successively. This kind of speed regulating motor currently has a fixed series of products to choose , such as single-winding multi-speed motor.
