  • Publication number: 20030173839
    Abstract: A rotary electric machine includes a rotor for rotation around a rotational axis, a stator core that has a cylindrical shape and includes a slot therein, a cooling unit having a coolant passage, and a casing that accommodates the rotor and the stator core. A stator coil is inserted in the slot of the stator core and has a coil end protruded from a side face of the stator core. An electric part is mounted on the cooling unit and controls a current of the stator core. The rotor is rotatably supported inside of the stator core. The cooling unit cools both the stator core and the electric part. The cooling portion is accommodated in spacing defined by the side face of the stator core and an outer circumference wall of the coil end.

  • Patent number: 6459980
    Abstract: A vehicle has a power system, in which an engine, a motor, a torque converter, a transmission, and an axle are connected in series. The transmission has a mechanism of varying a gear ratio under the control of a control unit. A driver of the vehicle operates a specific switch for setting a deceleration to specify a desired deceleration by means of power source braking. In response to an ON operation of a snow mode switch, a possible range of setting of the deceleration is restricted to a specific area that does not cause any slip or skid of the vehicle. The control unit totally controls the torque of the motor and the gear ratio, thereby implementing the braking at the desired deceleration. This arrangement attains the desired deceleration specified by the driver in the wide possible range of the setting, while restricting the deceleration to a specific range according to the driving conditions of the vehicle.

  • Publication number: 20020036434
    Abstract: A hybrid-vehicle drive unit supports a motor-generator with high precision, improving the efficiency of the motor-generator, and reducing the size of the motor-generator, independent of any influence of centering precision of the crank shaft and of deformation of the torque converter. According to the invention, a motor housing is disposed between a converter housing and an internal combustion engine, and a bearing is fitted to a lateral wall provided in a front portion of the motor housing. Rotor supporting members are independently supported by the bearing. Eccentric rotation of the crank shaft resulting from explosive vibrations of the engine is counteracted by two flex plates. Owing to a predetermined clearance, one of the rotor supporting members as a separate component is free from the influence of deformation of the torque converter.

  • Patent number: 6340339
    Abstract: A vehicle drive device is provided having a first source of driving force and a hydraulic transmission, into which power is input from the first source of driving force, arranged axially. A motor that transmits power by an electromagnetic action between a stator and a rotor is arranged between the first source of driving force and the hydraulic transmission. The stator is arranged to be radially distant from the rotational center axis of the hydraulic transmission. A small diameter portion formed to have a smaller outer diameter than an inner diameter of the stator is formed at a motor side of the hydraulic transmission and the hydraulic transmission is arranged with the small diameter portion being inserted axially into the inner periphery of the stator. As a result, the axial length of the vehicle drive device is shortened to thereby provide a small-size, lightweight device.

  • Patent number: 5668879
    Abstract: A scrambling system includes a scrambling apparatus and a descrambling apparatus for scrambling and descrambling digital audio codes having plural sub-band units. Each sub-band unit includes at least a scale factor and a quantized sample data which is quantized after scaling with the scale factor. In the scrambling apparatus, a sample period during which the quantized sample data is present is detected, and only the quantized sample data is scrambled at the sample period. In particular, the quantized sample data and data other than the quantized sample data are separated, and the separated quantized sample data is applied to a scrambler, and the other data is applied to a delay circuit. The separated and scrambled quantized sample data and the delayed data are synthesized. The descrambling apparatus also detects a sample period during which the quantized sample data is present, and descrambles only the scrambled quantized sample data at the sample period.
