BRAZING METHOD OF STATOR WINDING, BRAZING CORRECTION METHOD OF STATOR WINDING, AND STATOR WINDING OF ROTATING ELECTRIC MACHINE

摘要

PROBLEM TO BE SOLVED: To obtain a brazing method which easily performs preplaced brazing between all brazing faces, and easily keep brazing intervals between element wires constant.;SOLUTION: The brazing method of the stator winding comprises: a first process which is a preparation step of obtaining element wire bundles of prescribed sizes by aligning a plurality of the hollow element wires composed of hollow wires, and bonds metal coatings on external peripheral faces of the hollow element wires in order to keep the intervals between the hollow element wires; and a second process in which a plurality of the element wire bundles obtained at the first process are sequentially laminated and inserted into a coolant feeding/discharging box having an opening in a state where a lid is removed, brazing materials are sandwiched between the element wire groups, between the element wire bundles and the coolant feeding/discharging box, and between the lid and the coolant feeding/discharging box, and a stator winding end is obtained by brazing the brazing materials between the element wires by raising a temperature to a brazing temperature in the atmosphere in a state where the lid is arranged at the opening of the coolant feeding/discharging box.;COPYRIGHT: (C)2010,JPO&INPIT
