Abstract
A rotary electric machine, such as a vehicular AC generator, including a rotor rotatably driven; and a stator having a stator iron core disposed to face the rotor and stator windings mounted at the stator iron core, the stator windings being composed of a plurality of electric conductors made from aluminum and copper. For example, the plurality of stator windings are different in materials from each other winding by winding, the materials being either the aluminum or the copper. Alternatively, the plurality of stator windings include windings each being made, part by part, from different materials, the different materials being the aluminum and the copper.
