Electromagnetic Processes in a Three–Phase Induction Device Under Load

Induction heating is a method for thermal treatment of metals. The method has found a wide application due to the small power losses and the possibility for local heating of the treated parts. When a three–phase induction device is operating at an industrial frequency, a rotating magnetic field occurs, which limits the use of such devices. In the present work, a device is proposed which eliminates this problem, and for the purpose of the work, the study of the electromagnetic processes in the proposed device was carried out in an under–load mode.
