What's the total number of ac motor governor? The most common, each principle, the detailed point, the master thank you Please be more careful, the principle means thank you
Ac motor is the most ideal speed regulation in the current mode of speed adjustment, in other ways, it can be controlled by electromagnetic speed, variable speed and speed adjustment
Ac motor speed governor generally refers to the electromagnetic speed regulating motor controller. Now the gear speed machine, also called ac motor speed, the best you know that will you use it first.
Now the best ac motor speed performance is frequency conversion governor, it is accomplished by changing motor power frequency speed regulation, large range of speed regulation, and the energy conservation, will be, slow growth, and can be a starter motor, but the price is relatively high. Another kind is called a magnetic transmission, price close to the inverter, but different principle, characterized by long service life, less maintenance, existing at present in large motor speed control applications. Simple ac motor speed regulator can adopt the method of current limiting, step-down, like electric fan speed governor, this control method is simple, but the load characteristics of the motor is poor, is only applicable to small motor and load stability.
