PROBLEM TO BE SOLVED: To provide a DC brushless-motor unit capable of setting a larger angle of lead of an applied-voltage phase aginst an induction-voltage phase. SOLUTION: The DC brushless-motor unit of which the rotation is controlled by an inverter comprises the inverter that passes a current to each phase in the DC brushless motor based on a control signal, a reference-voltage generation means that outputs a reference voltage as a reference signal, a position-detection means that detects a rotational position of the DC brushless motor based on the induction voltage of the DC brushless motor and the reference voltage, a control means that outputs a control signal to the inverter based on the result of detection of the position by means of the position-detection means and a reference-voltage control means that controls the level of the reference voltage. |
