Abstract:
The present invention relates to a drum driving apparatus and a drum washing machine having same, the drum driving apparatus which enables driving force of various characteristics, which is required during washing and spin-drying in a drum washing machine, to be efficiently provided to a drum by means of a combination of a double-rotor/double-stator motor and a planetary gear device that plays the role of a transmission. A drum driving apparatus, according to the present invention, comprises: a double-rotor/double-stator motor which is mounted on the back of a tub and generates an outer rotor output and an inner rotor output that can be controlled independently; and a planetary gear device which receives an outer rotor output through a sun gear as a first input and then generates a reduced first output from a carrier, receives an inner rotor output through a ring gear as a second input and then generates a second output without reduction from the carrier, and applies the first and second outputs to a drum shaft connected to a drum.
