Publication number: 20090309363Abstract: An electrical generating system. A wheel that is eight feet in diameter is turned with a motor that is powered by battery. The battery is charged by a battery charger that supplies power to the battery twenty four hours a day. The size motor needed to turn the wheel will depend on the size of the generator that is needed to supply the electricity to a particular size building. The wheel has a built in shaft in the center of the wheel. The shaft sits on a pair of burring rings that are held up by a steel frame. The wheel can spin freely.Type: ApplicationFiled: June 12, 2008Publication date: December 17, 2009Inventor: Salvatore Rocco Uglietto

Patent number: 7622840Abstract: There is provided a method of using an electric machine. To generate torque, electricity is provided to stator coils on a plurality of salient poles of a stator arranged around a rotor having a plurality of salient poles to pull the rotor salient poles in the circumferential direction. To generate electricity, the method comprises rotating the rotor and generating a magnetic field on a magnetizing member. The magnetizing member is arranged coaxially with the rotor and offset from the rotor in the axial direction. The method further comprise conducting the generated magnetic field to the salient poles of the rotating rotor to induce alternating magnetic flux on the stator coils, and recovering electricity generated by the induced alternating magnetic flux from the stator coils. The generated magnetic field does not change its configuration when the rotor rotates except for distances between the closest pairs of rotor salient poles and stator salient poles.Type: GrantFiled: July 20, 2006Date of Patent: November 24, 2009Assignee: Mazda Motor CorporationInventors: Kei Yonemori, Nobuhide Seo

Patent number: 7615903Abstract: An electromechanical transmission is provided with a structural support member that supports a motor/generator in a space efficient way; particularly, the motor/generator is supported from one side only to save space axially in the transmission. Specifically, a stationary structural support member circumscribes an outer surface of and supports a stator while extending radially-inward of a rotor and at least partially supporting the rotor. A rotor hub rotatable with respect to the structural support member is used to support an inner surface of the rotor. The structural support member substantially encloses the stator and rotor from one direction along the axis of rotation. However, the stator and rotor have no additional support members in the opposing axial direction such that they are unenclosed from an opposing axial direction.Type: GrantFiled: April 27, 2006Date of Patent: November 10, 2009Assignee: GM Global Technology Operations, Inc.Inventors: Alan G.
