Document Type and Number:
WIPO Patent Application WO/2019/107985
Kind Code:
A1
Abstract:
A washing machine according to an embodiment of the present invention can increase the drive torque value of a drive motor by appropriately changing the coil wire diameter and the number of coil windings thereof without changing the reduction ratio of a planetary gear, the size of the drive motor, and the height of laminated stator cores. Specifically, the rotational speed ratio between the drive motor and a pulsator, obtained by the planetary gear, is 3.8:1, the height of the laminated stator cores is 13.5mm-14.5mm, and the number of coil turns is 100-140 inclusive.
