What are the advantages of brushless motors?

Brushless motors are composed of permanent magnet rotors, multi-pole winding stators, position sensors, etc. The position sensor changes the rotor position and commutates the current of the stator winding in a certain order (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. After being processed by the signal conversion circuit, it controls the power switch circuit and switches 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 output of the position sensor.
