BENDING DEVICE OF ROTOR COIL OF ROTATING ELECTRIC MACHINE, AND COIL FORMATION METHOD

PROBLEM TO BE SOLVED: To shorten connecting work such as thickness matching work and brazing work in a rotor coil manufacturing process, to reduce the number of part items which constitute a rotor coil, and to eliminate the exchange of a winding jig. SOLUTION: This bending device of the rotor coil of a rotating electric machine which bends and forms the rotor coil wound to a magnetic pole core of the rotating electric machine comprises: a copper belt feed-out mechanism 25 which feeds out a flat-type conductor having a predetermined coil forming size; a forming head 23 into which a flat copper belt 2 fed out of the copper belt feed-out mechanism 25 is inserted, and which bends and forms the flat copper belt into the coil forming size; an XY table 39 which is mounted with a coil 1 formed by the forming head 23, synchronized with the forming direction of the flat copper belt, and moves in an X direction or a Y direction; and a rotating table 46 which turns the XY table 39 in synchronization with the bending direction of the flat copper belt when bending and forming the flat copper belt in an edgewise direction by using the forming head 23.
