摘要： The present invention prevents the degradation of the power generating efficiency of an alternating current generator by preventing the expansion of an air gap formed between pole cores and a stator core, achieves low-noise operation by preventing generation of high-frequency impact magnetic noise, and makes it possible to relieve strains applied on a magnet holder. The present invention utilizes sixteen magnets, each of which fits between two of sixteen claw-like magnetic poles formed on the outer periphery of Lundell-type pole cores, which rotates integrally with a shaft. The magnets are caught and stopped by a magnet holder which has been formed by interconnecting zig-zagging segments and has elasticity as a whole. Here, the permanent magnets are held by the magnet holder so that the magnet holder does not protrude towards the rotor side from the outer peripheral face of the Lundell-type pole cores and the contacting faces of the magnet holder contact the outer faces of the permanent magnets. The claw-like magnetic poles are disposed so as to face the stator.

摘要： An automotive alternator according to the present invention includes a rotary shaft, slip rings, a brush holder, brushes, a cover, a seal member, a cooling air flow path, and a water shield. The slip rings are fixed to an end portion of the rotary shaft. The brushes are accommodated in the brush holder and so held by the brush holder as to establish sliding contacts with the slip rings to excite the automotive alternator. The cover covers the end portion of the rotary shaft, the slip rings, the brush holder, and the brushes. The seal member is interposed between the brush holder and the cover. The cooling air flow path is formed between the seal member and one of the brush holder and the cover to supply cooling air to the brushes. The water shield works to prevent water from entering into an entrance of the cooling air flow path.

摘要： A rotary electric machine has a brush assembly that defines a slip ring cavity enclosing slip rings and brushes. The brush assembly provides two different outlets for particles and cooling air. The first outlet is located on a side with respect to a shaft and is directed in an axial backward direction. The second outlet is located on a bottom and is directed in a radial downward direction. The second outlet is close to a fan for inducing airflow in the slip ring cavity.

摘要： Cooling wind is introduced into an electric-parts-chamber through openings formed at the bottom of a cover, then taken into the intake side of a cooling fan through the air intakes formed in the wall end of a housing from the electric-parts-chamber. The cooling wind is accelerated by the fan to be driven off from the outlets formed in the peripheral wall of the housing. The cylindrical portion of the positive side cooling fins of the rectifier is extended to the space between the outer periphery of the fan and the outlets. The inner diameter of the cylindrical portion is longer than that of the rear coil end. Thus, the coil end and the cylindrical portion of the positive side cooling fin are cooled sufficiently by the cooling wind blowing thereon at high speed, so that the rectifier can endure large thermal load with reduced wind noise even if the size of the alternator is small.
摘要翻译：冷却风通过形成在盖的底部的开口引入电气部件室，然后通过形成在壳体的壁端的空气入口从电气部件室进入冷却风扇的进气侧。冷却风由风扇加速，以从形成在壳体的周壁上的出口驱除。整流器的正侧冷却片的圆筒部分延伸到风扇的外周和出口之间的空间。圆筒部的内径比后线圈端的内径长。因此，通过在其上高速吹送的冷却风，充分冷却正侧冷却片的线圈端部和圆筒部，从而即使交流发电机的尺寸小，整流器也能够以较低的风噪声承受大的热负荷。

摘要： In the resin shield circuit device, a resin case is provided with a recess having an opening. Each end of connector terminals is exposed out of the resin case and the other end thereof is embedded into the resin case. Base portions of wiring metal pieces are embedded into the resin case and connected in circuit with the other ends of the connector terminals. Connecting portions of the wiring metal pieces protrude into the recess. Lead terminals of circuit elements are connected and fixed to the connecting portions, respectively. A resin shield portion filled in the recess covers the circuit elements and the connecting portions of the wiring metal pieces in such a manner that only a flat surface of the resin shield portion is exposed out of the opening of the recess to outside.
