PROBLEM TO BE SOLVED: To ensure the brazing of straight-angle conductors at a shaft length side and at a perimeter length side comprising a rotor coil with a stable temperature control. SOLUTION: The brazing arrangement of the rotor coil is configured to attach a channel shape wax foil 6 at a brazing position of a straight-angle conductor at a shaft length side 2 and a straight-angle conductor at a perimeter length side 3 with a wax foil attaching device, and then to position a high-frequency electric heating inductor body 49 comprised of water-cooled pipe 46 and laminated cores 47, 48 by a positioning holding mechanism 8 on an insulation / heat resistance ceramic flat plate 5 arranged on a flat surface of a a high-frequency electric heating inductor 4 fixed within a casing 44 by coagulating an insulation / heat resistance plaster 50. And, the top surface of the brazing position of the straight-angle conductor at the shaft length side 2 and the straight-angle conductor at the perimeter length side 3 is fixed at a butt position P by pressing with a top side pressing mechanism 9 so as not to develop a step. Under this condition, temperatures are measured at the brazing position with an infrared radiometer 10, and a heating temperature control is designed to be made by giving the feedback of the measured temperatures to a high-frequency electric heating power circuit.
