ELECTROMAGNETIC INDUCTION HEATING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an electromagnetic induction heating device characteristically composed by using an electromagnetic induction heating coil having a strip-like and uniform heating characteristic. SOLUTION: A winding structure 3 similar to that of a stator of a conventional linear motor or an A.C. rotary machine is applied; a polyphase alternating current of a commercial frequency or a high frequency exceeding it is carried to the respective windings 3 from a power conversion device 2 for outputting a plurality of alternating currents relatively different in phase; and an electric conductor 5 used as a heating object of the electromagnetic induction heating is disposed at a place where an original moving member is disposed to generate either a moving magnetic field or a rotating magnetic field. Thereby, the electric conductor 5 can be uniformly heated in a strip-like form. COPYRIGHT: (C)2005,JPO&NCIPI
