Filed:

Oct 18, 2002

Appl. No.:

10/274420

Inventors:

Jack H. Kerlin - Springville UT, US

Assignee:

Raser Technologies, Inc. - Provo UT

International Classification:

H02P 144

US Classification:

318751, 318747, 318752, 318794, 318254

Abstract:

In a resonant motor system, an electrical motor having a stator with one or more windings, a rotor which may or may not be wound, and an air gap between the stator and the rotor for storing magnetic energy such that the motor exhibits a definite electrical inductance may be deployed with a drive combination including a capacitance connected in series with the inductance of the motor to form an LCR circuit therewith. Phased provision of DC power to the LCR circuit causes the circuit to oscillate, which excites the motor. The DC power is provided in synchronism with the rotation of the rotor in order to maximize torque produced by the motor.

International Classification:

H01R 39/08

US Classification:

310232

Abstract:

A slip ring assembly for transferring electrical current to an electrical device is disclosed. The slip ring assembly has a housing that is attachable to the electrical device. Disposed within the housing is a rotatable slip ring and a flexible conductor. The flexible conductor is configured to conform to the shape of the slip ring and conduct an electric current. A fluid is contained within the housing. The fluid forms a conductive film between the slip ring and the conductor when the slip ring rotates through hydrodynamic forces. The conductive film is operative to transfer electrical current between the slip ring and the conductor while also preventing wear of the slip ring and conductor.

Assignee:

RT Patent Company, Inc. - Wilmington DE

International Classification:

H02K 17/00

US Classification:

310166, 310254, 310261

Abstract:

There is provided an electric motor having a flat form factor. The electric motor has a rotor with a shaft attached thereto. The rotor further includes a plurality of teeth disposed thereon. The motor further includes a stator having an axial length. A plurality of teeth are disposed on the stator such that a gap is defined between the teeth of the stator and the teeth of the rotor. The motor further includes a plurality of copper windings disposed around each of the teeth of stator. Each of the windings has a length of end copper equal to about twice the axial length of the stator. In this regard, the end of the wire is greater than the width of the stator such that the form factor of the motor can be flattened.

International Classification:

H02K 31/00

US Classification:

310178

Abstract:

An AC unipolar generator provides high power at high frequencies without requiring a source of high-frequency mechanical power. A rotor having a plurality of spaced magnetic disks and two sets of rotating capacitor plates is coupled to a source of mechanical power, the two sets of rotating capacitor plates being spaced apart along the outside of the rotor and electrically connected via a conducting channel. A stator surrounding a portion of the rotor that includes the magnetic disks and one of the two sets of rotating capacitor plates includes a magnetic stator core that forms a magnetic circuit with the magnetic disks of the rotor, a stator field coil, and a fixed set of capacitor plates that capacitively couple the stator field coil to the rotor conducting channel through one of the sets of rotating capacitor plates. A second fixed set of capacitor plates located outside of the stator capacitively couples the rotor conducting channel back to the stator field coil through the other set of rotating capacitor plates. The stator field coil and the two sets of capacitor plates form a resonant LC circuit that characterizes the AC frequency of the power generated by the generator.

Abstract:

A toroidal motor having a generally circular rotor surrounded by an annular stator is disclosed. The rotor has a plurality of poles disposed about a circumference thereof. A shaft extends axially away from the poles and is attached to the rotor. The stator is generally annular and includes an annular winding surrounding the circumference thereof. Disposed about the winding are a plurality of stator poles. The number of stator poles is generally equal to the number of rotor poles. When the winding and hence the stator is excited, a magnetic field is produced between the stator and rotor poles that creates torque upon the shaft.

Abstract:

In accordance with the teachings herein, systems and methods are described for providing electrical contact with a rotating element of a machine. In one example system, a nozzle may be used to emit a stream of a molten metal material, the nozzle being configured to transmit electric current from a power source to the stream of molten metal material. The rotating element may be supported within the machine to rotate relative to the nozzle, and may include a current collector ring. The nozzle may be operable to emit the stream of molten metal material onto a localized portion of the current collector ring to transfer the electric current from the power source to the current collector ring, the localized portion of the current collector ring being a portion of the current collector ring that is less than an entire circumference of the current collector ring.
