ROTATING ELECTRIC MACHINE AND METHOD FOR MANUFACTURING SAME

A rotary electric machine according to the present invention includes a stator having a connection member forming a three phase delta connection by coil windings. In the rotary electric machine, the connection member is composed of an insulating annular groove portion formed with double annular grooves and a first, a second, and a third annular conductive members, the annular conductive members being attached by insertion into the insulating annular groove portion; the insulating annular groove portion is formed with double grooves of one and the other, and both the grooves are connected via one window portion; the respective annular conductive members are each formed in a circular arc shape and provided with a plurality of arm portions extended outward in the radial direction of the stator, the plurality of arm portions being connected to coil end portions of the coil windings respectively; the first annular conductive member and the second annular conductive member are attached by insertion into different grooves of the insulating annular groove portion, are overlapped at a part of opened sections where a circular arc is not present, are in a positional relationship in which both annular conductive members are opened, and are attached by insertion so that the window portion is disposed at the position where both annular conductive members are opened; and the third annular conductive member is made such that a portion to be attached by insertion into one groove and a portion to be attached by insertion into the other groove are attached by insertion into the insulating annular groove portion via the window portion.
