Abstract

The high precision of the superconducting magnetic levitation device relies on the rotor's high-speed rotation and disturbance resistance. In actual work, the appropriate support current is conducive to realizing the high-speed driving of the superconductor rotor and improving its anti-disturbance ability. A comprehensive analysis of suspension current characteristics in superconducting magnetic levitation systems is therefore essential. This study analyzes the suspension current characteristics in superconducting magnetic levitation systems. The structure is first introduced, followed by a finite element model based on the vector magnetic potential equation to investigate electromagnetic relationships. A suspension current adjustment method is then proposed and validated through experimental tests. In conclusion, an analysis was conducted to determine the influence law of the change in suspension current on the drift speed. This analysis was based on the change in interference torque caused by the change in suspension current. The results establish a framework for optimizing suspension current adjustment and serve as a benchmark for improving device accuracy.

磁悬浮超导转子结构悬浮电流分析

超导磁悬浮装置的高精度依赖于转子的高速旋转和抗干扰能力。在实际工作中，适当的支撑电流有利于实现超导体转子的高速驱动，提高其抗干扰能力。因此，对超导磁悬浮系统的悬浮电流特性进行全面分析是必要的。本文分析了超导磁悬浮系统的悬浮电流特性。首先介绍了结构，然后建立了基于矢量磁势方程的有限元模型来研究电磁关系。提出了一种悬架电流调节方法，并通过实验验证了该方法的有效性。最后，分析了悬架电流变化对漂移速度的影响规律。该分析基于悬架电流变化引起的干涉转矩变化。研究结果为优化悬架电流调节建立了框架，并为提高器件精度提供了基准。

期刊介绍： Physica C (Superconductivity and its Applications) publishes peer-reviewed papers on novel developments in the field of superconductivity. Topics include discovery of new superconducting materials and elucidation of their mechanisms, physics of vortex matter, enhancement of critical properties of superconductors, identification of novel properties and processing methods that improve their performance and promote new routes to applications of superconductivity. The main goal of the journal is to publish: 1. Papers that substantially increase the understanding of the fundamental aspects and mechanisms of superconductivity and vortex matter through theoretical and experimental methods. 2. Papers that report on novel physical properties and processing of materials that substantially enhance their critical performance. 3. Papers that promote new or improved routes to applications of superconductivity and/or superconducting materials, and proof-of-concept novel proto-type superconducting devices. The editors of the journal will select papers that are well written and based on thorough research that provide truly novel insights.
