Abstract
A washing machine according to an embodiment of the present disclosure can obtain an effect that increases a drive torque value of a drive motor by appropriately changing a wire diameter of a coil and the number of turns of the coil without changing a reduction ratio of a planetary gear, a size of the drive motor, and a stacking height of a stator core. In detail, a rotational speed ratio between the drive motor and a pulsator, obtained by the planetary gear, is 3.8:1, the stacking height of the stator core is 13.5 mm to 14.5 mm, and the number of turns of the coil is 100 to 140.
