Brushless motor uses semiconductor switch devices to achieve electronic commutation, that is, electronic switch devices instead of traditional contact commutators and brushes. It has the advantages of high reliability, no commutation spark, low mechanical noise and so on. It is widely used in high grade recordings, video recorders, electronic instruments and automation office equipment.
Brushless motor is composed of permanent magnet rotor, multi pole winding stator, position sensor and so on. According to the change of the rotor position, the position sensor changes the stator winding current in a certain order (that is, to detect the position of the rotor magnetic pole relative to the stator winding, and to produce the position sensing signal at the determined position. After the signal conversion circuit is processed, the power switch circuit is controlled, and the winding current switching is carried out 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.
