Abstract

It is an object of this invention to provide an alternator for a vehicle in which all electric conductors forming bridge portions are sufficiently exposed to cooling winds so that the cooling performance is remarkably improved. It is another object of this invention to provide an alternator for a vehicle which is excellent in cooling performance, insulating characteristic, and heat resisting property. An alternator for a vehicle includes a stator. The stator includes an iron core 22, an electric conductor 21, and an insulator 23. The electric conductor 21 forms a winding on the iron core 22. The insulator 23 provides electric insulation between the electric conductor 21 and the iron core 22. The stator is supported by a housing. The dimension of openings of slots in the iron core 22 is smaller than the distance between inner side surfaces of the slots. The electric conductor 21 has accommodated portions accommodated in the slots, and bridge portions connecting the accommodated portions. Pieces of the electric conductor which extend out of the slots are approximately separated into a conductor groups 21f located on outer radial sides of the slots and a conductor group 21g located on…
