An approach accounting for the losses in a three-phase induction device

摘要

Induction heating and melting is a widely used thermal treatment method. It is associated with small losses of electric power and it's also enables local heating at specific points of the item. In using three-phase inductors at industrial frequency, a problem occurs associated with the occurrence of a rotating magnetic field. The construction suggested in this publication eliminates this problem. This publication proposes a methodology for theoretical and experimental study of the currents and power capacities in all three phases of the three-phase induction device with a split phase operating in idle mode with taking into account the losses in the magnetic core and the wires.
