The working principle of DC brushless motor

The brushless DC motor power system is composed of three parts: rotor, stator and 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, it detects the position of the rotor pole relative to the stator winding, and generates 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 an electronic switch circuit controlled by the output of the position sensor. There are three types of position sensors: magnetic sensitive, photoelectric and electromagnetic

The DC brushless motor adopts magnetic-sensitive position sensor, and its magnetic-sensitive sensor components (such as Hall element, magneto-sensitive diode, magneto-sensitive pole tube, magneto-sensitive resistor or application-specific integrated circuit, etc.) are installed on the stator assembly. To detect the change of the magnetic field generated when the permanent magnet and the rotor rotate.
