STATOR FOR ROTATING ELECTRIC MACHINE AND MANUFACTURING METHOD FOR THE SAME
First Claim
1. A rotating electric machine stator, comprising:
- a core having a plurality of magnetic pole portions;
coils wound around the respective plurality of magnetic pole portions;
jumper wires for electrically interconnecting the coils adjacent to each other by way of wires integral with the adjacent coils; and
connecting members for electrically connecting between the jumper wires placed at different positions, whereinthe connecting members each include a plurality of open-figured ports made of conductors that are opened toward an end-face of the core, and an interconnection conductor that is a conductor for interconnecting the plurality of open-figured ports; and
the jumper wires are inserted and fixed in the open-figured ports being directed toward the end-face of the core, to electrically connect the wires to the open-figured ports.

Abstract
The present invention relates to a rotating electric machine stator that includes connecting members for connecting jumper wires to each other between neighboring magnetic pole coils of the rotating electric machine stator, and its manufacturing method. In a conventional connecting member, its portions to be connected to the jumper wires are figure-U shaped and have openings on the opposite side to a core'"'"'s end-face where the jumper wires are disposed, so that, in order to insert the jumper wires into the openings, complex drive controls have been required for the connecting portions being figure-U shaped. In order to simplify the drive controls, such connecting portions being made in curved shapes have openings each facing the end-face of a core. It is possible to generally apply the present invention to rotating electric machine stators that obey coil connection specifications.
