1, no brush, brushless electric machine machine advantages to low interference in addition to the brushless motor brush, the most immediate change is without the motor running when the electric spark, thus greatly reduce the electric spark interference of remote radio equipment. 2, low noise, smooth operation brushless motor without brush, less friction force during operation, smooth running, low noise will many of the advantages of model running stability is a huge support. 3, long life, low maintenance costs less brush, brushless motor wear is mainly on the bearing, from the mechanical point of view, brushless motor is almost a maintenance-free motor, when necessary, the only need to do some cleaning maintenance. Next comparison, know brushless motor relative to have advantage in where the brush motor, but everything is not absolute, a brush motor torque at low speed performance, large torque and other performance characteristics is irreplaceable brushless motor, but in the context of use and ease of brushless motor, with the decline in the cost of brushless controller and the development of brushless technology at home and abroad and field competition, the development and popularity of power system is high speed brushless stage, it also greatly promote the development of the model of motion.
