Motor control is what?
Before answering this question, Xiao Bian consult the professionals in this area in order to allow them to learn more professional, and that the following website www.wxaxd.com to specifically expand its contents, as are about brushless motor control area.
Motor control means which starts the motor , acceleration, running, deceleration and stopping , etc. These aspects of the control , and to achieve quick start response purposes , and high torque , high efficiency , high overload purposes .
Start motor control , start the three-phase induction motor with full voltage direct start , buck up and start to increase the rotor circuit resistance of these three ; startup mode single-phase asynchronous motors are capacitor start , the resistance started , PTC start , etc. ; for synchronous motor, synchronous speed of the rotor is rotated , so there is no slip , but sometimes out of step , then you can not be self-starting , and it has a startup mode frequency start , start and linear induction motor drive motor from the start .
Control motor speed , the first look at its speed control method , there are strings resistance control, frequency control, pole-changing speed , etc., which are three ways corresponding to different motors. But by adjusting the size of the motor field and armature current , the motor can torque, speed and control , such as counter-electromotive force , to achieve the desired purpose , and therefore very simple .
