Compared with brush motor controller, what are the advantage of the brushless motor controller

Brushless motor controller compared with brush motor controller without a brush, but it has the following advantages. 1. Because in addition to the brush, brush motor controller when the operation is not produced in the electric fire, therefore reduced the edm to remote control the interference of radio equipment. 2. Because there is no brush, make sure when running more smoothly, and the friction small, low noise. 3. Because little brush, make its wear and tear on the bearing, mainly to reduce the maintenance cost, only need to do some cleaning maintenance. The above is to the advantage of the brushless motor controller, hope to help you.
