Patent number: 11773525Abstract: 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.Type: GrantFiled: March 4, 2020Date of Patent: October 3, 2023Assignee: Whirlpool CorporationInventors: Krati Bhargava, Fang Deng, James B.

Patent number: 11750046Abstract: 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.Type: GrantFiled: March 18, 2021Date of Patent: September 5, 2023Assignee: Whirlpool CorporationInventors: Krati Bhargava, Fang Deng, James Hull
