<p><P>PROBLEM TO BE SOLVED: To provide an electromagnetic induction heating method and device for a core of a rotating electric machine capable of uniformly heating core plates in the vicinity of both ends of the core to a core plate in the vicinity of an intermediate portion in the thickness direction. <P>SOLUTION: An inner peripheral side coil 14 and an outer peripheral side coil 15 which have cylindrical shapes, respectively are arranged on the inner peripheral side and the outer peripheral side of the core W of the rotating electric machine formed to have a cylindrical shape as a whole by laminating the plurality of core plates Wa. In this state, AC current is passed to respective coils 14, 15 so as to perform electromagnetic induction heating of the core W. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
