摘要： A small-diameter fin and a large-diameter fin, each extending in a direction normal to an axial direction of a rotor, are disposed at both sides of a terminal base so as to be overlapped in the axial direction of the rotor. The small-diameter fin is disposed far from the rotor compared with the large-diameter fin. The small-diameter fin is provided with a plurality of independent ribs each protruding in the axial direction of the rotor and extending in a radial direction of the rotor from or along an opening periphery of the receiving hole of the rectifying element.

摘要： A stator winding includes at least two pairs of in-slot portions aligned in a depth direction of each of slots and first and second coil-ends that respectively extend from opposite axial ends of the slots. The first coil-end a includes a plurality of crossover wires, each of which connects one of the in-slot portions disposed in one layer of the one of the slots and another of the in-slot portions disposed in another layer of second one of the slots that is spaced apart from the first one of the slots by a narrower pitch than a pole-pitch between the N and S poles. The second coil-end includes a plurality of crossover wires, each of which connects one of the in-slot portions disposed in one layer of third one of the slots and another of the in-slot portions disposed in another layer of fourth one of the slots that is spaced apart from the third one of the slots by the pole-pitch between the N and S poles. Therefore, the height of the first coil-end can be reduced, so that the rigidity of the coil-end can be increased, thereby increasing vibration resistance.

摘要： A stator winding of an alternator has two poly-phase windings. Each of phase coils, e.g., X-phase coil in one of poly-phase windings, is provided by a continuous wire. The phase coil is accommodated in corresponding slots in a layered manner along a radial direction, therefore, the phase coil forms layers in the slots and may be identified as location of layers in the slots. The phase coil has a plurality of crossing portion that links the layers in different slots distanced by a magnetic pole pitch, and two output portions extending beyond the stator winding. In the phase coil, only one crossing portion is formed to link the same layers in different slots, and the other crossing portions are formed to link different layers in different slots.

摘要： In an engine auxiliary unit driving equipment for transmitting an engine driving force from a crank pulley to a plurality of engine auxiliary units including an alternator, a driven poly-V pulley provided at least in the alternator has a plurality of grooves extending in a circumferential direction. A poly-V belt, which has a plurality of projections extending in a longitudinal direction so as to correspond to the grooves of the driven poly-V pulley, bridges between the crank pulley and the driven poly-V pulley. The poly-V belt is substantially divided in an axial direction of the driven poly-V pulley into two pieces each having plural pieces of the projections. Accordingly, a tensile strength acting in a width direction of the poly-V belt is substantially divided midway between the divided poly-V belts so that cracks in the round poly-V belt hardly occurs, resulting in securing a longer lifetime of the poly-V belt. Further, a natural frequency of the poly-V belt around the alternator maybe shifted to restrict a belt flapping increase due to resonance at an idling time when a revolution fluctuation is larger.
摘要翻译：在用于将发动机驱动力从曲柄皮带轮传递到包括交流发电机的多个发动机辅助单元的发动机辅助单元驱动设备中，至少设置在交流发电机中的从动多V型滑轮具有沿圆周方向延伸的多个凹槽。具有沿着纵向方向延伸以便对应于被驱动的多V带轮的槽的多个突起的多V带桥接在曲柄皮带轮和被驱动的多V带轮之间。多维带V带沿着被驱动的多V带轮的轴向大致分为两片，每片具有多个突起。因此，在多V带的宽度方向上的拉伸强度基本上分开在分割的多V带之间的中间，使得圆形多V带中的裂纹几乎不发生，从而确保聚 - V带。此外，交替发电机周围的多V带的固有频率可能偏移以限制在旋转波动较大时在怠速时的共振时的带振荡增加。

摘要： A generator for alleviating fluctuations in instantaneous rotational speed of an internal combustion engine is included in a belt-drive system. When an average rotational speed of the generator is lower than a predetermined speed, e.g., an idling speed, a generation torque of the generator is controlled to reduce the belt tension fluctuations. When the average speed of the generator is higher than the predetermined speed, the generator is controlled in a usual manner to supply a stable power to the electric loads.

摘要： In a vehicle AC generator, a plurality of conductor segments having connection-ends is connected to form a stator winding. Each pair of the connection-ends is welded to each other side by side to align in a radial direction thereby forming a ring of the connection-ends disposed at equal intervals on an end of the stator core. Each pair of the connection-end has a recessed portion for preventing a welded portion of the connection-ends from swelling out of the recess in the circumferential direction.

摘要： Providing a pulley unit with a reduced diameter, stable operating characteristics, and that is simple and readily removable from an engine is accomplished by a one-way clutch disposed between a pulley and a shaft body that are concentrically arranged. A shaft defines a shaft attachment space at a position which is not overlapped by rollers contained in the one-way clutch in an axial direction. The shaft body is attached to the shaft at the shaft attachment space. The shaft body, disposed inside the rollers in a radial direction, does not have a through hole, but rather, has a non-through structure.

摘要： A rotary electric machine has two sub-windings shifted by 30 degrees from each other. Each sub-winding is connected to an individual bridge which has MOS transistors on the ground sides. It is possible to supply a charging current even at a low rotational speed by switching the MOS transistors at a high-frequency. The basic components of magnetic force are canceled because of the shifted sub-windings. The switching components of the magnetic forces generated by the switching operation are canceled by switching two groups of the MOS transistors in opposite states. As a result, it is possible to decrease the magnetic noise significantly.
