【Abstract】 By using VDMOS field-effect transistors(FET)as the switch elements, the electronic controlling circuits of the PM brushless DC motor, including the main power switch circuit, power driving circuit, absorption circuit, and logic controlling circuit, are designed. After experiments on one sample motor with this electronic circuit, every part of it can work dependably and normally. The experimental datas show that the motor can satisfy every demand of the desighing.更多还原
