Brushless motor controller is belong to the dc motor controller or ac motor controller?

brushless motor controller is belong to the dc motor controller or ac motor controller? Many clients there is a question that is the brushless motor controller is belong to the dc motor controller or ac motor controller? Will discuss this problem together with you today. Have the characteristics of the brushless motor controller is everything actually external characteristic of dc motor controller adopts electronic commutation of the motor controller is referred to as the brushless motor controller. Due to the presence of the brushless motor controller, broke the communication, strict boundaries between dc speed regulating system. Appeared in the history of the brushless motor controller two distinctive brushless motor controller structure, namely the brushless dc motor controller and ac type commutation brushless motor controller. Brushless dc motor controller of electric energy finally by way of dc supply. According to the direct current (dc) can get way, brushless dc motor controller usually on - Straight - And in control system Two main implementation ways in control system, also known as the square wave. And ac type commutation brushless motor controller is using thyristor inverter to 50 hz alternating current (ac) directly into a frequency change with rotor ac supply motor controller, the speed regulation characteristic and dc motor controller approximation. Main input is the wave of the motor controller and now. As you can see, in fact than ac type commutation brushless motor controller of brushless dc motor controller way is much more complicated, in the back of the name, actually also differ, brushless dc motor controller has been used the old name, and ac type commutation brushless motor controller is called a permanent magnet synchronous motor controller. If phase switcher integration within the motor controller, the input is a dc can still be called is dc motor controller, but high-power phase switcher outside the motor controller, so after phase switcher supply motor controller is actually an alternating current. Brushless dc motor controller with the permanent magnet synchronous ac motor controller structure is very similar, the difference is that the input of the brushless dc motor controller is square wave, the input of the permanent magnet synchronous motor controller is sine wave. So in fact, both the dc brushless motor controller, also have communication, basically be to see demand to choose.
