摘要： PROBLEM TO BE SOLVED: To improve the balance of the whole AC generator for vehicle.
SOLUTION: A stator includes: a winding U21 arranged on the bottom of a slot; a winding U11 having the same phase as U21 out of the other independent three-phase windings having a phase difference of about 30 degrees in terms of an electrical angle with respect to the three-phase winding including a wound wire of the winding U21; a winding V22- having a different phase from the winding U21 and the winding U11; and a winding U12 having the same phase as the winding U11 and connected in series thereto. In an AC generator for the vehicle, U21, U11, V22-, and U12 are disposed so that an inductance connecting the winding U11 and the winding U12 in series becomes almost equal to the inductance connecting the winding U21 and the winding V22- in series.

摘要： PROBLEM TO BE SOLVED: To provide a housing for reducing cast defects, improving a yield, and facilitating a refrigeration in a built-in rectifier if the housing with a coolant path 20 is formed by die-casting.
SOLUTION: The first and second cylindrical housings 14, 15 have bottoms and openings at one end. The openings face and abut on each other. The third housing 16 is fixed on inner circumferences of the first and second housings. A stator 5 of a power generator is attached to the third housing. The refrigeration path 20 is circumferentially formed between the inner circumferences of the first and second housings and an outer circumference of the third housing. A coolant is circulated in the refrigeration path. An axial length is reduced, a die-casting process is simplified, the coolant is surely prevented from being leaked, and the stator 5 and the built-in rectifier 33 are effectively refrigerated by divided housings 14, 15.

摘要： PROBLEM TO BE SOLVED: To provide a more preferable rotating electric machine for a vehicle. SOLUTION: This rotating electric machine includes a stator in a concentrated winding structure in which one phase stator winding is wound around one magnetic pole, and a rotor which is arranged so as to face the stator and rotate through a gap and is provided with 16 magnetic poles or more. The magnetic pole ratio of the rotor to the stator is defined to be 2:3. The vehicular alternator most often uses a rotational speed of approximately 3,000 r/min. At such a rotational speed, entire loss including both of iron loss and copper loss is reduced, thus obtaining high efficiency. COPYRIGHT: (C)2009,JPO&INPIT
