FIELD: electrical engineering.
SUBSTANCE: device is made in the form of multi-pole rotor. The rotor includes excitation windings installed on ferromagnetic cores of the inductor coil; windings are mainly superconducting and direct current can be supplied to them. The cores are placed into rotating cryostat; the coolant is pumped through the cryostat suitable for induction of eddy currents in materials to be cut during rotation of the rotor. Eddy currents provide heating and melting of material. At that electromagnetic force arises along tangent towards direction of the rotor rotation thus tearing off a melted layer of the material being cut. At ferromagnetic cores of the inductor coil there are polar tips with tooth area providing maximum non-uniformity of magnetic field in the working gap to speed up heating.
EFFECT: superconducting winding provides significant increase of the inductor coil magnetic field.
