  • VEHICLE WITH BOTH ASYNCHRONOUS AND SYNCHRONOUS ELECTRIC DRIVES
    Publication number: 20120299513
    Abstract: A rotary electric machine having plural rotary elements in a non-coaxial arrangement is disclosed. The rotary electric machine includes a housing assembly, at least one stator frame mounted in the housing assembly, at least one stator winding wound on the at least one stator frame, and at least two rotors mounted in the housing assembly having axes of rotation that are non-coaxial, wherein each of the at least two rotors is mechanically decoupled from the other rotors such that each of the at least two rotors rotates independent from one another. The rotary electric machine also includes a control unit, with the control unit including at least one electronic control electrically connected to the at least one stator winding. The control unit is configured to control an exchange of power to or from each of the at least one stator windings.
