摘要： A rotating electrical machine includes an annular coil connection body provided coaxially with a stator. The coil connection body has, in a groove provided on a holder, an overhang portion for restricting an axial-direction movement of a terminal, and a positioning projection for restricting a radial-direction movement of the terminal. The positioning projection positions the terminal such that a part of the terminal overlaps the overhang portion in the axial direction. In this structure, when the terminal moves in a direction from a terminal holding portion toward a groove opening, the terminal comes into contact with a side surface of the overhang portion, whereby lifting and coming-off of the terminal can be prevented.

摘要： A rotary electrical machine includes a stator and a rotor. The stator includes a plurality of iron cores that are annularly disposed, windings that are wound to each of the plurality of iron cores, connection terminals to which the windings are connected to, and molded members that partially cover the plurality of iron cores and the windings. The rotor rotates around an axis that coincides with a circular center of the plurality of iron cores. The molded members have resin portions that cover the plurality of iron cores and the windings, and a plurality of exposed terminal portions that expose the connection terminals.

摘要： There is provided an electric power steering apparatus in which constituent elements of a control unit for controlling one of 2 winding groups of a motor and constituent elements of a control unit for controlling the other one thereof are arranged in point symmetry with respect to a center axis of an output shaft or in line symmetry with respect to a virtual straight line perpendicular to a direction in which the output shaft extends.
