Abstract: A stator for a rotating electric machine includes a cylindrical stator core and a stator winding. The stator winding includes inserted portions, which are inserted in slots of the stator core, and connecting portions that are located outside of the slots to connect the inserted portions. Each of the inserted portions has a rectangular cross section with a pair of long sides and a pair of short sides. In each of the slots, each of those inserted portions which are located on the radially inner side has the short sides of its cross section arranged perpendicular to the radial direction of the stator core; each of those inserted portions which are located on the radially outer side has the long sides of its cross section arranged perpendicular to the radial direction. The circumferential width of each of the slots increases in the radially outward direction of the stator core.

Abstract: The rear cover of a vehicle-use AC generator is integrally formed with a portion that is shaped to enclose at least a part of a circumferentially extending region around the slip rings of the generator. Hence the rear cover, alone or in combination with an appropriately shaped brush holder, serves to seal the region of contact between the slip rings and brushes against intrusion of foreign matter, without the use of sealing members for preventing such intrusion.
