  • Patent number: 6833648
    Abstract: A sequentially joined-segment coil for a rotary electric machine such an electric motor is provided. The coil has an end portion which is made up of heads of conductor segments and projects from an end of a core. The heads of conductor segments have turns or bulges. The bulges are lapped over one another in various forms or shifted in location in an axis direction of the core, thereby permitting the core to be decreased in diameter, which provides for decreases in size and weight of the rotary electrical machine.
    Type: Grant

  • Patent number: 6825589
    Abstract: Provided is a multi-turn sequential segment joining stator coil capable of suppressing the differences in electromotive voltage between parallel circuits and of carrying a large current. Partial coils are accommodated in a plurality of continuous conductor accommodation positions of different slots. The partial coils accommodated in the same slot are separately connected in series to each other to produce parallel coils, and the produced parallel coils are connected in parallel with each other. This configuration enables the production of a sequential segment joining stator coil type electric rotating machine with a size-reduced head-side coil end.

  • Patent number: 6774528
    Abstract: Three partial coils are accommodated in inphase slots arranged successively in the circumferential direction and also accommodated in the same conductor accommodation position set. Each layer coil is constituted by serially connecting these partial coils. Respective layer coils are connected in parallel to each other to form a phase winding.

  • Patent number: 6590312
    Abstract: A rotary electric machine for a hybrid vehicle includes a rotor connected between a vehicle engine and a torque transmission mechanism at the back of the vehicle engine and a stator. The rotor includes an outer rotor portion having an inner surface electro-magnetically connected to the outer surface of the stator, an inner rotor portion having an outer surface electro-magnetically connected to the inner surface of the stator. The stator includes a stator core disposed between the inner rotor portion and the outer rotor portion and a multi-phase winding wound on the stator to be electro-magnetically connected with both the outer and inner rotor portions.

  • Patent number: 5917248
    Abstract: A T-S converter is composed of a first rotor which has a first control coil, a second rotor and a stator which has a second control coil. The second rotor has a first magnetic field member (such as permanent magnets) which supplies the first control coil with magnetic field and a second magnetic field member (such as permanent magnets) which supplies the second control coil with magnetic field. The first and second control coils are energized to drive the second rotor to rotate at a set speed with a set torque according to vehicle running condition. The first and the second control coil are also energized to generate battery charging current when the vehicle speed is decreased and the second rotor is driven by the vehicle wheels.
