1 principle analysis of brushless dc motor work leave the electronic switch circuit, so the ontology by motor, rotor position sensors and electronic switching circuit of three parts, the brushless dc motor control system, its structure diagram is shown in figure 1. Dc power supply power to the motor stator winding through the switch circuit, position sensor detecting the rotor position at any time, and according to the position signal to control the switch tube conduction and globe, model aircraft, motor በራስ-ሰር በኃይል ቁጥጥር የሚቆጣጠር, የኤሌክትሮኒክስ መጓጓዣን የሚተገበር አውሎ ነፋሶች የኤሌክትሮኒክስ መጓጓዣን ይፈጽማሉ.
