Abstract: A drive system of a washing machine includes a housing, a motor, a rotor shaft coupled to the motor and the housing, an output shaft having a part within the rotor shaft and coupled to the housing, a planetary gear set coupled to the rotor shaft and the output shaft, and an actuator configured to move the planetary gear set in a vertical direction. When the planetary gear set is moved to one side, a part of the planetary gear set is coupled to the rotor shaft to transmit a rotational force of the rotor shaft to the output shaft at a ratio of 1:1. When the planetary gear set is moved to other side, another part of the planetary gear set is coupled to the housing to reduce the rotational force of the rotor shaft at a gear ratio of n:1 and transmit it to the output shaft.
