  • Rotary induction heater having a direct-current exciter
    Patent number: 11785679
    Abstract: The invention relates to a rotary induction heater with direct-current excitation for heating solid or liquid or gaseous substances. The alternating magnetic field required for induction or for generating inductive heat is generated with a direct-current coil having a constant magnetic field. The constant magnetic field is converted into an alternating magnetic field by way of a rotating mechanical component.
