Stator winding arrangement of alternator for vehicle

摘要

An alternator (1) for a vehicle includes a fan for supplying cooling air along an inner circumference of coil-end groups (31) disposed opposite ends of a stator (2) in an axial direction. Each of the coil-end groups (31) is composed of a plurality inner coil-end portions (33a) disposed at an inner circumference of the coil-end groups (31) to extend from an end of the stator core (32) and outer coil-end portions (33b) disposed at an outer circumference of the coil-end groups (31) to extend from an end of the stator core (32). The inner coil-end portion extends in a direction between the axial direction and rotating direction of the rotor (3).
