Abstract: A method of determining and utilizing an Energy Efficiency Indicator, the method initiating with a step of determining a distal or angular offset between a pair of coupled shafts provided between adjacent rotating machines. The offset is correlated to energy efficiency between the pair of coupled shafts. Correlation is referred to as an Energy Efficiency Indicator (EEI). The Energy Efficiency Indicator (EEI) can be used to predict changes in alignment, changes in energy efficiency, and the like. Monitoring the coupled rotating machines and using the Energy Efficiency Indicator (EEI) can provide the operator with predictive information to enhance the reliability and extend the lifespan of the coupled rotating machines.

Abstract: A method of generating and controlling power for an alternating current (AC) motor by means of at least one controlled permanent magnet machine (PMM) with a permanent magnet (PM) rotor and a stator with a magnetic flux diverter circuit for controlling the output of the PMM, comprises the steps of: rotating the PM rotor at a velocity sufficient to develop a high frequency alternating current (HFAC) power output from the stator; transforming the HFAC output to produce a variable low frequency alternating current (AC) motor control output for the motor; sensing desired motor control parameters; generating a control signal responsive to the sensed parameters; and applying the control signal to the magnetic flux diverter circuit to control the motor control output.

Abstract: The present invention includes a power system that is designed to provide reliable electrical power to a facility, and specifically to a telecommunications facility. The system includes a number of proton exchange membranes (PEMs) adapted to provide DC power. The system is configured so that the PEMs receive fuel from a header that is supplied by a number of hydrogen generators. Storage tanks are also included to provide hydrogen to the header if the hydrogen generators fail. The hydrogen generators receive electricity initially from an array of photovoltaic panels. If the photovoltaic panels fail then AC power from a commercial utility is provided to the hydrogen generators. Finally, the system includes a number of super capacitors that are operable to maintain power during the time required to change between power sources.

Abstract: A power output apparatus 110 includes a planetary gear 120 having a planetary carrier, a sun gear, and a ring gear, an engine 150 having a crankshaft 156 linked with the planetary carrier, a first motor MG1 attached to the sun gear, and a second motor MG2 attached to the ring gear. When the driver steps on an accelerator pedal 164 to change the driving point of the engine 150, the power output apparatus 110 calculates an angular acceleration of the sun gear, calculates a torque used for changing the driving point of the engine 150 by multiplying the angular acceleration by a moment of inertia seen from the first motor MG1 of an inertial system consisting of the first motor MG1 and the engine 150, and drives the second motor MG2 by taking into account the torque. This structure enables a desired torque to be output even in a transient time.

Abstract: A hybrid electric vehicle includes an internal combustion engine, a multi-speed automatic transmission, and an electric machine operable in a motoring mode and a generating mode. A compound planetary gear set operatively couples the engine, transmission and electric machine. The electric machine is operable during periods of vehicle launch to provide a reaction torque for the planetary gearset such that torque is supplied to the input of the transmission and the reaction torque energy is converted to electrical energy for storage in a vehicle battery pack battery. The method employs a combination of open loop torque control and closed loop speed controls responsive to rotational parameters of the vehicle drivetrain including engine speed, electric machine rotor speed and transmission input speed to control the generator torque of the electric machine to thereby produce the reaction torque for accelerating the vehicle and for producing electrical power during the vehicle launch.

Abstract: An apparatus for economical travel and minimization of atmospheric degradation by internal combustion exhaust products. A car which has, in combination, a heat engine driving a set of front wheels, storage batteries and an electric motor driving a set of rear wheels. There is also a system for selecting electric or heat engine drive either manually or automatically and a single accelerator for controlling either mode of drive. A battery charging system supplies a constant power charge rate. Battery charging power is derived from the electric motors acting as generators driven by the rear wheels while the vehicle is in heat engine drive, and the battery charging rate is selected by the operator. Also in combination is a regenerative braking system to recover expended energy in the form of vehicle motion and an overdrive system to increase vehicle speed in the electric drive mode by field weakening.
