Patent number: 8186038Abstract: A method for building a component for an electrical rotating machine is provided. The method includes providing a powdered magnetic material and an electrically conductive material, positioning these materials within a mold selected to produce the required dimensions in the materials after the application of a hot isostatic pressing (HIP) procedure, and applying at least one HIP procedure to the materials in the mold. Temperatures and pressures of the process are chosen to ensure that the electrically conducting and magnetic portions of the component are bonded without the materials seeping into each other. The method may be employed to build small compact motor systems using motor components formed as described to produce uniform grain structure and consistent magnetic and structural properties in the motor components that are useful in vehicle drive wheels.Type: GrantFiled: September 6, 2006Date of Patent: May 29, 2012Assignee: Borealis Technical LimitedInventors: Jonathan Sidney Edelson, Maynard Leo Stangeland, Donald Henry Morris, Robert Lincoln Carman, Jr.

Patent number: 8146369Abstract: A starter/generator machine for a turbine with a turbine enclosure, an air duct, and a plurality of fan blades is provided. The starter/generator machine includes a plurality of stator elements spaced at intervals in a ring shape adjacent to the air duct and a plurality of rotor elements mounted on the fan blades. The stator elements and the rotor elements are mounted to interact magnetically to exert a force sufficient to move the rotor elements. The stator elements are shaped to minimize air flow interference and are formed with a core, at least one pole, and multiple windings. The spacing between the stator elements and the rotor elements forms an air gap on the order of 5-10 mm, and the number of stator elements is different from the number of rotor elements.Type: GrantFiled: November 6, 2008Date of Patent: April 3, 2012Assignee: Borealis Technical LimitedInventors: Hans Juergen Walitzki, Jonathan Sidney Edelson, Rodney Thomas Cox

Patent number: 7905813Abstract: An apparatus for controlling the power output of an unthrottled engine has a variable gear ratio transmission connected between a mechanical load and the engine, and it has a controller for controlling the torque load on the engine, according to the power output required. The controller measures the torque output of the unthrottled engine at the power output required, and sets the gear ratio of the transmission to produce a torque load on the engine equal to the torque output of the engine. This means the unthrottled engine will reach an equilibrium with the mechanical load at the required power output. Controlling the unthrottled engine in this way involves receiving a signal describing the power output requirement, varying a gear ratio of the transmission, and establishing a torque equilibrium between the load and the engine.Type: GrantFiled: March 22, 2004Date of Patent: March 15, 2011Assignee: Borealis Technical LimitedInventors: Jonathan Sidney Edelson, Rochel Geller

Patent number: 7852037Abstract: This application describes a motor designed to operate as a reluctance machine at low speeds and as an induction machine at high speeds. The drive waveform is composed of one or more harmonics to be used to match the reluctance pattern of the stator-rotor, causing the rotor to rotate due to the reluctance effect, and one or more other harmonics to induce current in the rotor, causing the rotor to rotate due to the induction effect and the subsequent interaction of the stator and rotor magnetic fields. The two effects are generally not applied simultaneously.Type: GrantFiled: April 5, 2006Date of Patent: December 14, 2010Assignee: Borealis Technical LimitedInventor: Jonathan Sidney Edelson
