Patent ID: 7728473

Claim:
A method of manufacturing an electric rotating machine, including the steps of connecting a rotor winding constituting a part of a rotor and a leader line drawn to an outer diameter side from a conductor provided in a center portion in a radial direction of a rotor body for supplying electricity to the rotor winding from the outside, via a connecting line which is constructed by stacking a plurality of conductor plates and comprises a radial direction linear portion which is straight in the radial direction on the leader line side and a bending portion branching off into two routes toward opposite directions to each other in a rotor shaft direction from the radial direction linear portion and having a linear portion formed in a part of the bending portion, by electrically joining the linear portion of the bending portion and a bottom surface of the rotor winding, the connecting step including: inserting a cooling structure in a hollow part formed in the bending portion of the connecting line; subsequently, sandwiching a brazing material between the bottom surface of the rotor winding and the connecting line of the bending portion, and applying a brazing material flow inhibitor on the bending portion of the connecting line; and subsequently, heating the brazing material to melt the brazing material while flowing a cooling medium in the cooling structure, to join an outermost layer of the conductor plates and the bottom surface of the rotor winding.
