Alternator
An alternator includes a stator having an annular stator core provided with a number of slots extending axially disposed in lines circumferentially so as to open on an inner circumferential side and a stator coil wound into the stator core so as to be installed in the slots, a rotor having a number of claw-shaped magnetic poles for alternately forming north-seeking (N) and south-seeking (S) poles about a rotational circumference, the rotor being rotatably disposed on the inner circumferential side of the stator core, a bracket supporting the rotor and the stator, and a rectifier disposed at a first axial end of the stator and connected to end portions of the stator coil, the rectifier converting alternating current from the stator coil into direct current, wherein a number of slots is two per phase per pole, and the stator coil comprises a number of winding sub-portions in each of which a long strand of wire is wound so as to alternately occupy an inner layer and an outer layer in a slot depth direction within the slots at intervals of a predetermined number of slots by folding back the strand of wire outside the slots at axial end surfaces of the stator core.
