Brushless motor controller mainly has the advantages of the three, below small make up take you to understand it. 1. No brush, low interference. Because is brushless motor controller without brush, so not as a brush motor controller electric spark when operation, reduced the electric spark interference of remote radio equipment. 2. Low noise, smooth operation. Because it does not take the brush, the relatively small friction during operation, smooth running, low noise, so the stability is a big support of model operation. 3. Long life, low maintenance cost. Because there is no brush, so its wear mainly concentrated in bearing. From the mechanical point of view, it is a kind of maintenance-free motor, only need to do some cleaning maintenance. From what has been discussed above, we know about what are the advantages of the brushless motor controller?
