Abstract
A full automatic washing machine includes an outer tub, a rotatable tub mounted for rotation in the outer tub, an agitator mounted for rotation in the rotatable tub, a brushless motor for directly driving the agitator or the rotatable tub and the agitator, and a Hall IC for detecting a rotational position of a rotor of the brushless motor, generating a position signal. A sinusoidal energization signal is formed on the basis of the position signal generated by the Hall IC. The brushless motor is energized on the basis of the formed energization signal.
