Document Type and Number:
WIPO Patent Application WO/2013/070008
Kind Code:
A1
Abstract:
A motor for a washing machine according to the present invention comprises: an inner rotor which is connected to a drying tub rotary shaft, and which rotates therewith; an outer rotor which is connected to a pulsator rotary shaft, and which rotates therewith; and a double stator, which is arranged between the inner and outer rotors with spaces therebeween, having a first coil forming a first magnetic circuit by interacting with the outer rotor, and a second coil forming a second magnetic circuit by interacting with the inner rotor. A first activation signal is applied to the first coil, and a second activation signal, which is different from the first activation signal, is applied to the second coil, thereby allowing, by means of just the motor, selective rotation of the pulsator and the drying tub, thus the manufacturing costs can be reduced, manufacturing processes can be simplified, and the overall height of the washing machine can be lowered.
