Abstract: PROBLEM TO BE SOLVED: To sharply enhance the cooling performance by causing a cooling wind to blow against rectifying devices and cooing fins efficiently. SOLUTION: A large-diameter fin 503 is put on a frame 3b side, and a small- diameter fin 501 is put on a protective cover 8 side. Their rectifying devices 502, 504 are overlapped in the axial direction in a posture, facing each other with a gap of a specified width between. The large-diameter fin 503 is deviated on the radial outside, and a small-diameter fin 501 is deviated on the radial inside, and the protective cover 8 has an axial opening 801 for leading in the outside air directly to the positive rectifying device 502. Furthermore, a radial ventilating path 810 passing the center position of the negative rectifying device 504 is formed between the large-diameter fin 503 and a frame 3b, and at the radial outside end part of this radial ventilating path 810 a radial opening 802 for leading outside air in directly is formed. Since it is possible to pass a cooling wind through the gap between the device fitting surfaces of both fins 501, 503, it becomes possible to cause the cooling wind to be sucked in to satisfactorily blow against both surfaces of the cooling fins 501, 503 and to cool the fins 501, 503 and the rectifying devices 502, 504.

Abstract: PROBLEM TO BE SOLVED: To improve heat resistance and vibration strength and to achieve excellent cost effectiveness, by fixing a bush of almost cylindrical shape made of a thermosetting resin to a resin cover in such a way as to project in the direction of a rectifying device. SOLUTION: A mounting hole of a cover 11 is fitted to a bolt 12. Then, a rectifying device 10 and the cover 11 are secured with a nut 18 from the axial direction to a rear frame 4. In this case, the cover 11 is made of a low- cost thermosetting resin typified by a nylon resin. A bush, as the mounting hole of the cover 11, of a cylindrical shape pre-formed with the thermosetting resin is fixed by the insert molding in such a way as to project toward the rectifying device 10. This makes the cylindrical part of a bush 16 arranged between the bolt 12 and a + fin mounting hole and a terminal block mounting hole. Also, the bush 16 has a middle collar part which has a radial cross-section larger than the mounting hole of the + fin 15, and end surface collar part which serves as the tightening bearing surface of the nut 18, on its side end surface.

Abstract: PROBLEM TO BE SOLVED: To provide a brushless alternator for a vehicle that is reduced in size and weight without impairing its power generation capacity and can be inexpensively manufactured.
SOLUTION: The alternator includes a magnetic ring 25 fit to a field core 24 on the fixed side and extended in the axial direction. The magnetic ring 25 is so extended that it overlaps a field winding 23 in the axial direction. Therefore, it is possible to secure the area of an air gap 251 between the field core and a rotating magnetic pole core 222 of the other polarity and further shorten the axial length of the field core 24 and reduce its weight. In addition, magnetic flux can be infiltrated into the rotating magnetic pole core 222 of the other polarity opposed to the field winding 23. Therefore, it is possible to also reduce axial lengths of the rotating magnetic pole core 222 and a rotating core 224. Thus, the alternator 1 can be significantly reduced in size and weight as a whole.
