    摘要： An object of the present invention is to provide an automotive alternator achieving high output by overlapping a laminated core of a stator and yoke portion of a field rotor in an axial direction, and enabling electromagnetic noise to be reduced by prescribing dimensional relationships in the field rotor. In this automotive alternator, a ratio (R2/R1) between an outer radius R2 of a cylindrical portion of a Lundell-type core and an outer radius R1 of the Lundell-type core is set to a range from 0.50 to 0.54, and a ratio (Tr/Tp) between an axial overlap length Tr between the laminated core of the stator and the yoke portions of the Lundell-type core and an axial length Tp of the yoke portions is set to a range greater than or equal to 0.2.

    摘要： An alternator is capable of preventing a short circuit at a coil end, improving an ability of cooling a stator winding assembly, and reducing noises. A multi-phase stator winding of the alternator has: a plurality of joint portions where a distal end extending in an axial direction of a first conductor portion drawn out from a first layer in a slot and a distal end extending in an axial direction of a second conductor portion drawn out from a second layer in a slot located a predetermined number of slots apart in a circumferential direction are connected outside the slot on an end surface side of the stator core; and a coil end where the joint portions are disposed in a plurality of rows in the circumferential direction. The joint portions are set apart by half a slot from a diametrical line in a circumferential direction.

    摘要： A rotor for a dynamo-electric machine includes a rotor coil, a first pole core body disposed so as to cover the rotor coil formed with a plurality of first claw-shaped magnetic poles evenly spaced around a circumferential portion thereof being magnetized by magnetic flux, a second pole core body disposed facing the first pole core body having second claw-shaped magnetic poles spaced so as to intermesh between the first claw-shaped magnetic poles, a first magnetic body secured to the first pole core body which is magnetized in directions which reduce magnetic flux leakage with the second claw-shaped magnetic poles at each side surface of the first claw-shaped magnetic poles, and a second magnetic body secured to the second pole core body facing the first magnetic body across an air gap which is magnetized in directions which reduce magnetic flux leakage with the first claw-shaped magnetic poles at each side surface of the second claw-shaped magnetic poles.
