“A WASHING MACHINE.”
Application 2565/DEL/1998 published 2005-11-04, filed 1998-08-28
The present invention provides a washing machine comprising an outer tub, a rotatable tub rotatably mounted in the outer tub: an agitator rotatably mounted in the rotatable tub; a brushless motor provided for direct driving at least one of the rotatable tub and the agitator and having windings of plurality of phases, characterized in that the brushless motor comprising a rotor; a rotor position detecting element detecting a rotational position of the rotor of the brushless motor, thereby delivering a position signal representative of the rotational position of the rotor, the rotor position detecting element being smaller in number than the winding phases of motor; an energizing signal forming means for forming a sinusoidal wave energizing signal on the basis of the position signal delivered from the rotor position detecting element, and driving means for energizing the windings of the plurality of phases on the basis of the energizing signals delivered from the energizing signal forming means. The present invention is herein described with reference to the accompanying drawings.
