    Abstract: According to one aspect of the present disclosure, an electric motor for a laundry appliance includes a first stator having a central axis. A first rotor is in electromagnetic communication with the first stator and is rotationally operable about the central axis. A second stator is aligned with the central axis. A second rotor is in electromagnetic communication with the second stator and is rotationally operable about the central axis. The first and second stators are positioned within a common motor cavity of an outer housing. A controller regulates a first electrical current to the first stator and a second electrical current to the second stator. The controller includes a torque discrimination module for monitoring an output torque of at least the first rotor.

    Abstract: An axial flux motor for an appliance includes a stator yoke. A plurality of stator teeth extend from the stator yoke in an axial direction and are positioned about a central rotational axis. Each stator tooth includes a plurality of laminations that extend in the axial direction and form a “T” shaped member. The plurality of stator teeth are overmolded with a polymeric material to define a plurality of axial stator poles. At least one winding extends around the plurality of axial stator poles. A ring-shaped rotor rotates about the central rotational axis of the stator yoke. The rotor is positioned proximate an axial end of the plurality of axial stator poles.
