ABSTRACT:
A full-automatic washing machine includes an outer tub, a rotatable tub rotatably mounted in the outer tub, an agitator rotatably mounted in the rotatable tub, and a brushless motor for direct driving at least one of the rotatable tub and the agitator. The brushless motor including windings of a plurality of phases and a rotor. Also, the washing machine includes rotor position detecting elements to detect a rotational position of the rotor. The rotor position detecting element are less in number than the phases of the motor. An energizing signal forming element to generate a sinusoidal energizing signal for each of the phases based on the detected rotational position of the rotor. Last, a driving element to energize the windings of the phases based on the energizing signals.
