Brushless motor controller belongs to a kind of commonly used motor controller, are widely used in high-end audio, video, electronic instrument and automation of office equipment. Often use this motor controller may know brushless motor controller is composed of what, but still has a lot of people don't know, today we will look at the important constitute part of brushless motor controller. Mainly by the permanent magnet brushless motor controller, multipolar winding of the stator and rotor position sensors. Position sensing according to the change of rotor position, along a certain sequence of stator winding current converter (By detecting the rotor magnetic pole relative to the position of the stator winding, and in determining the location of the position sensor signal, the signal conversion circuit to control the power switch circuit, after processing according to certain logic relation between winding current switch)。 The working voltage of stator winding electronic switching circuit controlled by the position sensor output. More professional content, welcome to our website, believe that will be of some help to you.
