By the permanent magnet brushless motor controller, multipolar winding of the stator and rotor position sensor, etc. 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. Brushless motor controller in the development of our time is short, but as the technology increasingly mature and perfect got rapid development. Has been used in model aircraft, medical equipment, household appliances, electric cars, and other fields is widely used, and in shenzhen, changsha, Shanghai and other places to form certain scale industrial chain. Such as shenzhen weiye motor controller, a batch of professional manufacturers, such as changsha keda constantly promoting industry development in technology. In recent years, the brushless motor controller become a rapid development in the field of the model of a kind of power. Because of production and price, over the past few years brushless motor controller used in high-grade aviation model, now due to the rapid development of machining technology, brushless motor controller of lower production costs a lot of, it is into the model in the field of all levels, from electric remote control cars to electric remote control boat to electric model planes, everywhere.
