WASHING MACHINE DRIVING APPARATUS AND WASHING MACHINE INCLUDING SAME

WIPO Patent Application WO/2015/167255

A1

A washing machine driving apparatus of the present invention comprises: a double rotor-double stator type of drive motor that includes an inner rotor and an outer rotor that can be independently controlled by double stators and selectively generates an inner-rotor output and an outer-rotor output; a first inner shaft that transfers the inner-rotor output as a first input; a first outer shaft that is coupled to the outer periphery of the first inner shaft so as to be rotatable and transfers the outer-rotor output as a second input; a planetary gear device in which a gear ratio of a transmission output generated from a carrier when the first input is applied to a sun gear through the first inner shaft is controlled by the second input applied to a ring gear through the first outer shaft; and a protection unit for protecting the inner rotor, wherein the outer periphery of the protection unit is supported by the double stators. As a result, interference between the rotors and other components can be prevented so that the other components can be installed at a close location to the motor, thereby making better use of a space.
