摘要： An electric power steering system having high performance and high reliability. The electric power steering system employs, as a power supply, a wound lead storage battery in which a thin band-shaped positive plate, a thin band-shaped negative plate, and a band-shaped separator interposed between the positive and negative plates are wound to form a plate group and the plate group is immersed in an electrolyte. In a motor used for electric power steering, a plate-shaped conductor is employed as a connecting ring for electrical connection between a cable for introducing multi-phase AC power to stator coils and the stator coils.

摘要： A rotating electric machine comprises: a stator including a stator iron core having a plurality of slots and a stator winding incorporated in the plurality of slots; and a rotor rotatably disposed in the stator via a clearance; wherein a mold (i.e., a slot insulator) made of an insulating resin is brought into close contact with the surface of a projection (i.e., a tooth core) of the stator iron core, formed between the adjacent slots, the thickness of the mold at a portion of the projection wound with the stator winding being smaller than that of the mold at other portions. Thus, it is possible to provide the rotating electric machine in which thermal resistance generated between the stator winding and the stator iron core can be reduced, thermal transmittance of heat generated in the stator winding to the stator iron core can be enhanced, and the cooling efficiency of the stator winding can be enhanced.
