Abstract
A stator of a vehicle AC generator includes a stator core, a multi-phase stator winding formed from a plurality of conductor members. The stator winding has coil-ends at opposite sides of said stator core, and portions of the conductor members in each of the coil-ends are radially aligned to have fixed radial clearances therebetween for introducing cooling air and ensuring insulation of the conductor members.
