Shenzhen rc brushless motor supplier, the brushless motor uses semiconductor switching devices to realize 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 audio jacks, video recorders, electronic instruments and automated office equipment.
The brushless motor consists 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 order 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 determined 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.
