A brushless motor controller is disclosed. The brushless motor controller includes a control unit and a drive timing generation unit. The control unit detects a load state of the motor. The drive timing generation unit generates a normal energizing timing determined by the rotational position of the rotor. Also, the drive timing generation unit generates an advancing angle energizing timing determined by the rotational position of the rotor and advanced by a predetermined amount from the normal energizing timing, generates a delay amount that changes in correspondence with the detected load state of the motor and the rotational speed of the rotor, and generates a final advancing angle energizing timing delayed by the delay amount from the advancing angle energizing timing.
