PROBLEM TO BE SOLVED: To provide a brushless motor control device capable of efficiently driving a brushless motor from a low speed to a high speed free from influences due to fluctuation in detection position made by a position detector.SOLUTION: The brushless motor control device applies a three-phase AC voltage to a winding of the brushless motor, slowly rotates the three-phase AC voltage, detects the direction of the three-phase AC voltage when the output signal from the position detector changes, and stores the detection value in storing means as a correction value of the position detection signal of the brushless motor. When operating the brushless motor, the brushless motor control device controls the brushless motor using the motor position detection signal and the correction value of the position detection signal. With this, the position detector is given with a precise detection position correction function of the brushless motor to efficiently drive the brushless motor from a low speed to a high speed. |
