Abstract:
An assembly including first and second rotatable members which rotate about a common axis of rotation, the first member being connected to a first rotor and the second member being connected to a second rotor, the first and second rotors being concentrically arranged, the assembly further including a first stator including coils wound about a core, and a second stator including coils also wound about the core, the coils of the first stator separated from the coils of the second stator so as to provide no or minimal magnetic interference, the first rotor being rotatable in response to electrical current flowing in the coils of the first stator and the second rotor being rotatable about the axis in response to electrical current flowing in the coils of the second statorwherein the stator core includes first radially extending formations about which coils of the first stator are wound, and second radially extending formations about which coils of the second stator are wound.
