  • Generator and/or motor assembly
    Publication number: 20080067883
    Abstract: A generator and/or motor device that includes an inner stator having one or more inner coils, an outer stator shell having one or more outer coils, and a rotor assembly arranged radially between, and configured to rotate relative to, the inner stator and the outer stator shell. The rotor assembly has one or more outer magnetic elements adjacent to the outer coils and has one or more inner magnetic elements adjacent to the inner coils. An electromotive force may be generated in at least one of the inner and outer coils upon relative rotation of the rotor assembly. Alternatively, relative rotation of the rotor assembly may be caused upon an electromotive force being applied in at least one of the inner and outer coils. The rotor assembly may be attached to an input shaft. The rotor assembly includes a rotor spool to which the inner and outer magnetic elements are secured.
