An alternator for a vehicle includes: a rundel-type rotor including a cylindrical portion around which a field coil is wound, a pair of plate-shaped end plate portions which are arranged such that the end plate portions face both end surfaces of the cylindrical portion in the axial direction in an opposed manner, first claw portions which extend parallel to a rotary axis from one end plate portion, and second claw portions which extend parallel to the rotary axis from the other end plate portion, and a stator which is arranged on an outer peripheral side of the rotor with a rotary gap therebetween so as to face the rotor in an opposed manner, and has a laminated core on which an armature coil is wound. The between claw magnetic poles of the first and second claw portions is set to a optimum gap range to maximize output current.

A vehicular alternating current generator includes a Lundell rotor and a stator. The Lundell rotor includes a cylindrical portion around which a field coil is wound; plate-shaped first and second end plate portions disposed on both end faces in an axial direction of the cylindrical portion so as to face each other; a plurality of first claw portions extending in parallel with a rotational axis in a direction from the first end plate portion to the second end plate portion; and second claw portions extending in parallel with the rotational axis in a direction from the second end plate portion to the first end plate portion, the second claw portions being disposed circumferentially and alternately relative to the first claw portions. The stator is disposed on an outer periphery of the rotor so as to face the rotor with a small rotational air gap there between.

It is made easy for a stator winding to be wound around a stator core and degradation in efficiency is prevented as much as possible. A stator (6) includes a plurality of phases, i.e., of circumferentially divided stator magnetic poles (6a, 6b, 6c). The stator magnetic poles (6a, 6b, 6c) are each composed of an arcuate stator core (13) having a plurality of axially extending claw poles (16b) and a circumferentially elliptically wound stator winding (14). The stator magnetic poles (6a, 6b, 6c) are magnetically divided; therefore, magnetic flux leakage is reduced to improve efficiency. Air flowing between the stator magnetic poles (6a, 6b, 6c) can improve a cooling effect.
