Abstract: A power output apparatus (20) of the present invention includes a clutch motor (30), an assist motor (40), and a controller (80) for controlling the clutch motor (30) and the assist motor (40). The clutch motor (30) includes an outer rotor (32) linked with a crankshaft (56) of a gasoline engine (50) and an inner rotor (34) connecting with a drive shaft (22). The assist motor (40) includes a rotor (42) connecting with the drive shaft (22). A control CPU (90) of the controller (80) controls a first driving circuit (91) to enable the clutch motor (30) to carry out the regenerative operation. The clutch motor (30) accordingly regenerates energy corresponding to a slip between the outer rotor (32) and the inner rotor (34) as electric power.

Abstract: A Direct Current drive system with a multiplicity of applications including that of powering electric vehicles. The system contains a hybrid electric motor formed by a unique synchronous arrangement of two electrical motors, a primary and a secondary. The single input of Direct Current to the primary motor enables the secondary motor to operate on the Alternating Current generated in the primary motor, and in doing so captures the transformation of energy that takes place during the collapse of a magnetic field. This captured energy is then used to help drive the secondary motor, thus greatly increasing efficiency. A brake/alternator is included to provide a means of slowing/ stopping the motor while at the same time assisting in recharging the primary power source by sending current through a rectifier to the battery which powers the motor.

Abstract: A starter-generator of an automobile is disclosed which comprises a stationary field coil wound and disposed coaxially around the rotational axis. The rotor comprises a pair of field pole forming members on which circumferentially alternating field poles are excited by the magnetic flux generated by the field coil. Armature coils connected in Y-connection are disposed around the rotor, and the terminals of the armature coils are coupled to the inputs of a three-phase rectifier circuit (used when the starter-generator acts as a starting motor) and the outputs of a armature current switching circuit (used when the starter-generator acts as a charging generator) which controls the flow of current through the armature coils so that a rotating magnetic field is formed. The starter-generator further comprises a pair of auxiliary coils which are wound and disposed around the rotational axis at both sides of the armature in the neighborhood of the rotor.

Abstract: A rotary power module construction especially useful in computer room application. A motor-generator set consisting of an induction motor and synchronous generator is mounted vertically and a direct drive is provided between the components by an electrically insulating coupling. A flywheel is mounted on a shaft of the synchronous generator to provide a maximum ride through condition for short term power outages. A plurality of spider-like leg members envelop the flywheel providing retainment protection for the flywheel as well as providing a suitable support for the synchronous generator. The spider-like leg members are anchored to a plate member which is secured to a non-rotating part of the induction motor. The motor-generator set is encased within a housing that is serviced only from the front of the housing, thereby occupying a minimum amount of space in the computer room.

Abstract: When operating a synchronous machine as a synchronous generator, a suppression resistor is required across the main generator field. However when operating the synchronous machine as an induction motor, a current is induced in the main generator field which is typically greater than the current carrying capability of the suppression resistor.In order to overcome the foregoing problem, the present invention provides a centrifugally activated switch for mounting on a rotor and which provides an alternate current path for the induced current.

Abstract: Engine brake clutch device comprising a common system of the electric machine type for transformation of mechanical energy associated with a differential system (27) and with a clutch (28), the unit being placed between the engine and the transmission so as to be able to perform the clutching or the engine braking of the vehicle.

Abstract: An engine is composed of an exhaust turbine rotatable by the exhaust energy of an exhaust gas discharged from the engine, a generator coupled to the exhaust turbine, and a motor drivable by the generator. The energy recovered from the exhaust gas by the exhaust turbine is fed back to an output shaft of the engine through the generator and the motor. The engine may have a second exhaust turbine located downstream of the first-mentioned exhaust turbine in an exhaust passage for driving an intake air compressor. The exhaust gas may be introduced directly into the second exhaust turbine by a bypass passage. In a generator device used with the engine, the generator includes a rotor shaft coupled coaxially with a turbine wheel shaft of the exhaust turbine. The turbine wheel, the wheel shaft, and the rotor shaft are constructed of ceramics preferably as an integral structure. The rotor shaft is rotatably supported by oil floating bearings.

Abstract: A rotary electric machine (motor or generator) comprises a first functional member and a second functional member rotatable with respect to the first one. One of the two functional members comprises a plurality of permanent magnet poles distributed in a ring arrangement, while the other one comprises a plurality of switchable electromagnet poles disposed in a ring arrangement opposite the permanent magnet poles, with an air gap in between. The numbers of permanent magnet poles and electromagnet poles either may be exactly or almost the same. At least one electronic circuit means controlled by at least one sensor detecting the rotational relative positions of the two functional members is provided for switching the electromagnet poles in the respective suitable direction of current flow and for the period of time of functional suitable relative positions with respect to the permanent magnet poles.

Abstract: A dynamoelectric machine having a multiple of three poles and a corresponding multiple of three brushes is disclosed. Each of the poles are wound poles, two of each group of three poles being excited with a constant excitation during normal operation, the third of each group of poles being a control pole, excited so as to produce a flux that both varies in magnitude and reverses in polarity. With an input voltage connected to first and second brushes of each group of three, an output voltage may be derived from first and third brushes in a magnitude determined by the polarity and intensity of the field of the control pole. The machine is also adapted to provide mechanical output power from its rotating shaft, and also to accept input power from its rotating shaft. The output voltage obtainable may be varied between zero and the value of the input voltage, and also increased above the input voltage, and decreased below zero, reversing polarity.
