摘要:
An alternator includes a rotor for forming north-seeking (N) and south-seeking (S) poles about a rotational circumference, a stator having a stator core disposed facing the rotor and a polyphase stator winding installed in the stator core, and a bracket supporting the rotor and the stator, wherein the stator core includes a laminated iron core formed with a number of slots extending axially at a predetermined pitch in a circumferential direction, the polyphase stator winding includes a number of winding sub-portions in each 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, the strand of wire folding back outside the slots at axial end surfaces of the stator core to form turn portions, and the turn portions align in a circumferential direction to constitute coil end groups.
