Heat Transfer Analysis of Superconducting Magnetically Levitation Rotor Startup Process

Superconducting magnetic levitation rotors have good application prospects in fields, such as gravimeters, accelerometers, and inertial instruments. Aiming at the little research on the heat transfer characteristics of superconducting magnetic levitation rotor, this article introduces the structure of the superconducting magnetic levitation rotor and the heat conduction model. Then, the temperature relationship of the rotor at steady state is obtained and the surface radiation distribution of the rotor during temperature rise is calculated. The results show that the temperature accuracy of the superconducting magnetic levitation rotor is critical to the drift accuracy. The drift caused by temperature change mainly depends on the accuracy of mechanical components and the stability of the temperature control system, which can provide some reference for the safe operation of the rotor.
