Brushless motor is composed of permanent magnet rotor, multi-pole winding stator, position sensor, etc. According to the change of the rotor position, the position sensing commutation of the current of the stator winding is carried out in a certain order (that is, the position of the rotor magnetic pole relative to the stator winding is detected, and the position sensing signal is generated at the determined position. After the signal conversion circuit is processed, the power switch circuit is controlled, and the winding current is switched according to a certain logic relationship). The working voltage of the stator winding is provided by the electronic switch circuit controlled by the output of the position sensor.

1、 Brushless, low interference

Brushless motor removes the brush, and the direct change is that there is no electric spark generated when the brush motor is running, which reduces the interference of electric spark to remote control radio equipment.

2、 Low noise, smooth operation

Without the brush, the brushless motor will greatly reduce the friction during operation, run smoothly, and have much lower noise. This advantage is a huge support for the stability of the model operation.

3、 Long service life and low maintenance cost

Without electric brush, the wear of brushless motor is mainly on the bearing. From the mechanical point of view, brushless motor is almost a maintenance-free motor, which only needs some dust removal maintenance. By comparison, we can understand the advantages of brushless motor compared with brushless motor, but everything is not absolute. Brushless motor has excellent low-speed torque performance, large torque and other performance characteristics that can not be replaced by brushless motor. In terms of the convenience of use of brushless motor, with the decline of the cost of brushless controller and the development and market competition of brushless technology at home and abroad, brushless power system is at the stage of rapid development and popularization, It has greatly promoted the development of model movement.

Brushless motors use semiconductor switching devices to realize electronic commutation, that is, electronic switching devices replace traditional contact commutators and brushes. It has the advantages of high reliability, no commutation spark and low mechanical noise, and is widely used in high-end recording stands, video recorders, electronic instruments and automatic office equipment.
