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.
