ABSTRACT:
Full automatic washing machine, and method for controlling the same, the full automatic washing machine including a spinning tub2movably fitted in an outer tub1,a pulsator3rotatably fitted in the spinning tub2to be rotatable independent from the spinning tub2,a spinning shaft5rotatably supported on a shaft bearing case20for transmission of a rotating power to the spinning tub2,a washing shaft4for transmission of the rotating power to the pulsator3,a BLDC motor7having a rotor7band a stator7afor rotating the rotor7bas power is applied to the stator7a, and a clutch mechanism for switching a power transmission path of the BLDC motor7either to the washing shaft4or to the spinning shaft5in correspondence to a washing cycle, or a spinning cycle, thereby permitting noiseless, and stable switching of the rotation power within a short time when the rotating power is transmitted to the pulsator or the spinning tub from a driving part having the stator and the rotor.
