摘要： Plural auxiliary devices such as a water pump and a generator coupled to a serpentine belt-drive system are driven by an internal combustion engine mounted on an automobile vehicle. The generator is divided into a first generator having a pulley in which a one-way clutch is installed and a second generator having a usual solid pulley. Fluctuations in the belt tension caused by changes in instantaneous rotational speed of the internal combustion engine are suppressed or reduced by the one-way clutch installed in the pulley of the first generator. An inertia torque of a rotor of the first generator may be made higher than that of the second generator because effects of the inertia torque on the belt tension fluctuations are alleviated by the one-way clutch.
摘要翻译：耦合到蛇形带驱动系统的多个辅助装置如水泵和发电机由安装在汽车车辆上的内燃机驱动。发电机被分成具有安装有单向离合器的滑轮的第一发电机和具有通常的实心滑轮的第二发电机。通过安装在第一发电机的滑轮中的单向离合器抑制或减小由内燃机的瞬时转速的变化引起的带张力的波动。第一发电机的转子的惯性转矩可以高于第二发电机的转子的惯性转矩，因为通过单向离合器减轻了惯性转矩对带张力波动的影响。

摘要： A rotating electric machine for a vehicle includes magnet holders for holding permanent magnets. The magnet holder is fitted between adjacent two claw-like magnetic poles of pole cores, and plural permanent magnets are provided to be magnetized for reducing magnetic-flux leakage between the magnetic poles. The magnet holder includes a radial outer surface, and a protrusion that protrudes from the radial outer surface to a radial outside around a center in a circumferential direction. Therefore, a thickness of the radial outside surface of the magnet holder increases, and its rigidity can be increased. Accordingly, it can prevent the radial outside surface of the magnet holder from being deformed due to centrifugal force, and it can prevent the magnet holder from being damaged.

摘要： Each tooth of a stator core has circumferential projections at an inner tooth edge and circumferential notches at a base portion adjacent to a core back. A width of the teeth at the base portion is larger than a width of the same at the tooth edge. Therefore, the magnetic reluctance of the teeth does not increase. In addition, a plurality of the magnetic strips can be formed from a long and thin magnetic sheet. This increases the yield percentage of the magnetic strip and reduces a manpower of manufacturing the magnetic strip. Further, the notches make it easy to wind the magnetic strip into a cylindrical core.
摘要翻译：定子芯的每个齿在内齿边缘处具有周向突起，并且在靠近芯背的基部周向凹陷。基部处的齿的宽度大于其在齿缘处的宽度。因此，齿的磁阻不增加。此外，可以由长而薄的磁性片形成多个磁条。这增加了磁条的屈服百分比，并减少了制造磁条的人力。此外，凹口使得将磁条卷入圆筒形芯中变得容易。

摘要： A controller for an alternator driven by an output torque of an automotive engine mechanically through a belt is provided. The controller works to control an exciting current supplied to a field winding of the alternator so as to cancel a change in inertia torque of a rotor of the alternator arising from a change in speed of the engine, thereby minimizing a change in tension of the belt.

摘要： In a rotary electric machine with a stator elastic support structure, conductor segments of a stator winding, each which is formed into an approximate U-shape, are inserted into slots of a stator core in such a manner that leg parts of each conductor segment penetrate through the slots from one end of the stator core to the other end thereof and are connected at top ends. Further, the conductor segments are arranged to have a predetermined clearance between adjacent two thereof at both coil ends of the stator winding, and a cooling fan is disposed so that air is blown toward the clearances of the conductor segments. Accordingly, when the stator core is supported in a frame through an elastic member, a magnetic noise can be reduced while it can effectively prevent heat deterioration of the elastic member due to heat radiated from the stator core and the stator winding, in low cost.
摘要翻译：在具有定子弹性支撑结构的旋转电机中，定子绕组的形成为大致U形的导体段以定子芯的槽插入，每个导体段的腿部穿透通过从定子铁心的一端到其另一端的槽，并在顶端连接。此外，导体段被布置成在定子绕组的两个线圈端处在其相邻的两个之间具有预定间隙，并且设置冷却风扇以使空气朝向导体段的间隙吹送。因此，当通过弹性构件将定子铁心支撑在框架中时，可以降低磁噪声，同时可以有效地防止由于定子铁芯和定子绕组辐射的热而导致的弹性构件的热劣化。
