Abstract

A laundry appliance includes a drum that is rotationally operable about a rotational axis within a tub. The rotational axis is oriented in a generally horizontal configuration. An impeller is rotationally operable within the drum about the rotational axis. A dual-rotor motor is coupled to the drum and the impeller for providing separate and independent rotation of the drum and impeller about the rotational axis. An inner rotor of the dual-rotor motor is coupled with the impeller and an outer rotor of the dual-rotor motor is coupled with the drum.
