Brushless motor controller has the advantage of by no brush

Relative to a motor controller, the brushless motor controller has advantages are: 1. Because there is no brush, so won't produce edm at run time, avoid spark interference of remote radio equipment. 2. Because there is no brush, so its wear mainly focused on the bearing at run time. From the mechanical point of view, it is a kind of maintenance-free motor, only need to do some simple cleaning maintenance work. 3. Because there is no brush, so at runtime by the friction of the greatly reduced, and ensure smooth operation, and low noise.
