ABSTRACT:
A brushless motor controller that controls a brushless motor by determining an energizing timing of a three-phase stator coil based on the rotational position and speed of a rotor. The controller includes a normal timing generation unit, an advancing timing generation unit, and a control switching unit. The normal timing generation unit generates a normal energizing timing. The advancing angle timing generation unit generates an advancing angle energizing timing advanced by a predetermined amount from the normal energizing timing and a final advancing angle energizing timing delayed by a delay amount from the advancing angle energizing timing. The control switching unit switches rotation control of the motor between a first rotation control executed in accordance with the normal energizing timing and a second rotation control executed in accordance with the final advancing angle energizing timing.
