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(More)
Induction heating and melting is a thermal method of metal treatment widely used in practice. The advantages of this method are high speed of heating, great efficiency factor, small losses, possibility for local heating and others. The main problem of the three-phase induction devices with a radial position of the inductors is the presence of a rotating(More)
