Abstract: An armature for a rotating electrical machine, including an armature core and a coil wound around the armature core. The segment conductor includes a joint extension portion that extends in the axial direction relative to the armature core from at least one end portion of a conductor edge portion. The coil has an n-layer winding structure and includes an inter-layer joint portion on an axial direction outer side of the armature core. The inter-layer joint portion joining a first and second layer side joint extension portions. At least one of the first and second layer side joint extension portions forming a pair to be joined by the inter-layer joint portion includes an offset bend portion, and the first layer side joint extension portion and the second layer side joint extension portion are joined such that respective joint surfaces thereof oppose each other in a circumferential direction.

Abstract: An armature for a rotating electrical machine, the armature includes a cylindrical core having a plurality of longitudinally extending slots that are dispersedly arranged in a circumferential direction; and coils wound around the slots, wherein each of the slots is formed such that an inner circumferential opening thereof that is open radially inwardly is smaller in a circumferential width than a slot interior positioned on a radially outer side of the inner circumferential opening, and linear conductors forming the coils are each formed to be larger in the circumferential width than the inner circumferential opening.

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.

Abstract: A motor 12 includes a cylindrical rotor 20, a stator 19 arranged at a predetermined distance from an outer periphery of the rotor 20, and a position sensor 23 for detecting a rotational position of the rotor 20, wherein the stator 19 includes a stator core 19a and a plurality of stator windings 19b arranged along a circumferential direction of the stator core 19a at substantially equal distances from one another. A shield plate 26 for shielding magnetic flux from the stator windings 19b to the position sensor 23 is mounted against the stator core 19a. Magnetic flux from the stator windings pass through a closed loop starting from the stator windings 19b through the stator core 19a and the shield plate 26 and back to the stator windings to prevent the magnetic flux leakage from the stator windings 19b from flowing to another member. With this arrangement, the magnetic flux leakage from the stator windings does not affect the position sensor (magnetic sensor) which detects the rotational position of the rotor.

Abstract: A rotation detector resists magnetic disturbances from sources near the detector. The rotation detector includes a rotor on which iron magnetic path changing pieces are fixed at predetermined intervals. A first bias magnet and a first magneto-resistive element for detecting the flux of the first bias magnet oppose the magnetic path changing pieces. A magnetic guide plate is located to guide disturbing magnetic flux in predetermined directions. The disturbing magnetic flux thus fails to adversely affect the first magneto-resistive element.

Abstract: The present invention improves mountability of a drive train in a hybrid vehicle by minimizing axial and radial dimensions while providing for adequate output torque of the motor/generator of the drive train. A center portion of a front cover of a torque converter extends axially and a multiple disc lock-up clutch is arranged at the inner circumferential surface of the center portion while the motor/generator is arranged at the outer circumferential surface of the center portion. A spring damper is provided at the radially inner side of a circumferential surface defined by friction plates of the lock-up clutch.
