Abstract: A vehicle includes a power supply, at least two auxiliary electrical components, and a load that is shared by the auxiliary electrical components. The two auxiliary electrical components are connected electrically to the power supply in a series configuration. One or more loads may be connected mechanically to the auxiliary electrical components in a parallel configuration. In one embodiment, the two auxiliary electrical components may include at least two compressors for a cooling system.

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: 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.

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.

Abstract: An electromagnetic motor with increased torque. The motor has a rotor coil configured to generate a magnetic field. At least two stator coils are connected in series with the rotor coil. Each of the stator coils is configured to generate a respective magnetic field. The motor further includes a plurality of switches configured to generate the magnetic field in each of the respective rotor and stator coils. The switches are configured to generate the magnetic field in the stator coils such that the rotor coil rotates in response thereto. By having the rotor and stator coils connected in series, the torque of the motor is increased.

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.
