This invention discloses a superconducting melting device that uses a permanent magnet hollow motor to drive a low-temperature superconducting coil, belonging to the technical field of metal melting equipment. It includes a support base with a rotating connecting seat fixedly connected to its top. Through the linkage between the hollow motor and the low-temperature superconducting coil, when the hollow motor drives the hollow motor rotor to rotate, the rotor drives the low-temperature superconducting coil to rotate synchronously. The low-temperature superconducting coil directly generates a dynamic rotating magnetic field, which in turn forms a uniform rotating magnetic field inside the melting crucible. This rotating magnetic field directly acts on the stationary metal ingot, causing it to generate induced eddy currents and self-heat, melting it. Through the synergistic effect of the hollow motor and the low-temperature superconducting coil, the metal ingot can complete the transformation from solid to liquid in a completely non-contact state, avoiding the impurity introduction problem caused by direct contact between electrodes, crucibles, and other components and the molten metal in traditional melting methods. This achieves clean melting of highly active, high-purity metals.
