A brushless motor controller capable of reducing a starting current comprises a micro-controller, a driving component connected to the controller, a motor driven by the driving component, and a driving circuit connected to the motor. A three-phase winding connected to an output circuit is provided in the motor. The output circuit comprises a shift switching circuit and a three-phase bridge output circuit. The three-phase bridge output circuit comprises six pairs of power transistors connected to the driving component. Each of single-phase winding in the three-phase winding has two terminals connected to two pairs of power transistors respectively. The voltage on the single-phase winding is equal to the voltage applied to the motor. The controller can reduce a starting current of a brushless motor. |
