China Rc Brushless Motor Factory

- Feb 26, 2021-

In China rc brushless motor factory, the brushless DC motor uses semiconductor switching devices to achieve electronic commutation, that is, electronic switching devices are used to replace traditional contact commutators and brushes. It has the advantages of high reliability, no reversing sparks, and low mechanical noise. It is widely used in high-end audio jacks, video recorders, electronic instruments and automated office equipment.

The brushless DC motor is composed of a permanent magnet rotor, a multi-pole winding stator, and a position sensor. The position sensor commutation of the stator winding current in a certain sequence according to the change of the rotor position (that is, detecting the position of the rotor pole relative to the stator winding, and generating a position sensing signal at a certain position, which is processed by the signal conversion circuit To control the power switch circuit, switch the winding current according to a certain logical relationship). The working voltage of the stator winding is provided by the electronic switch circuit controlled by the position sensor output.
