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.

Abstract: A stator for an appliance motor includes an annular core made up of a metallic plate that is spirally wound into a laminated structure. An overmold extends around the core and further defines an interior section and a bridge section that extends between the core and the interior section. The interior section includes stator fastening portions that are used to attach the stator to a tub. The bridge section includes a first radial structure that extends from the interior section to the core. The bridge section includes a second radial structure that extends from the interior section to the core. The core, the interior section and the first and second radial structures define a toroidal cavity within the bridge section.

Abstract: A motor for a laundry appliance includes a drive shaft coupled to a drum at a first end. The rotor frame is coupled proximate the second end of the drive shaft, where the rotor frame includes at least one polymeric material. A central hub includes a core and a perimetrical ring that extends circumferentially around the core. A plurality of recesses are defined within a planar surface of the perimetrical ring, wherein a portion of the polymeric material is received within the plurality of recesses to secure the rotor frame to the central hub.

Abstract: A laundry appliance includes a drum rotationally positioned within a structural cabinet. An impeller is rotationally positioned within the drum. The impeller is selectively and independently operable with respect to the drum. A binary motor has a first motor and a second motor disposed within a common housing. A first drive belt extends between the first motor and the drum. A second drive belt extends between the second motor and the impeller. The first and second motors engage the first and second drive belts on a belt side of the common housing.
