Stator coil ends of an A.C. generator for vehicle

摘要

Coil ends (19) of a stator coil (18) having a cross sectional shape like a flat rectangular are constructed by first portions extending from an outer layer of a pair of slots apart from predetermined pitches in an axial direction and slanting in a circumferential direction, second portions extending from an inner layer of the other of the pair of the slots in the axial direction and slanting in the circumferential direction, and third portions positioned at ends of the coil ends (19) in the axial directions, elongated in the radial direction and connected to ends of the first and second portions in the axial direction, and in all of the first, second and third portions, long sides (300) of the cross sectional flat rectangular view of the stator coil (18) are arranged to be substantially in parallel with an end surface (17a) of the stator whereby the coil ends are lowered; and the coils are arranged without a gap.
