The tiles burning accident may happen with the temperature rising because of the severe friction if the axial load was very big for the thrust bearing. We proposes using maglev technology to reduce the load for the thrust bearing to avoid the accident. Based on the principle of not coupling the original system, a disc electrodynamic maglev machine is designed, which will provides a normal repulsion as the levitation force to offset one part of the axial load for the bearing with the advantages of good self-stability and light secondary. The tangential force generated at the same time and is useless. The electrical and structural parameters both affect two forces. This paper studied the analytical calculation method, the relationship of the two forces, and the energies stored in the air-gap and expended in the secondary. Then the laws of parameters affecting the forces are obtained, which reveal the design method to improve the levitation force and decrease the tangential force. Based on the theoretical research, the Coreless superconductor primary armature is thought most suitable for this machine with higher y-axis component of magnetic field in air-gap. The FEA simulation model is used to verify the theoretical analysis.

提高磁悬浮减载机悬浮力的研究

如果推力轴承的轴向载荷很大，由于摩擦剧烈，随着温度的升高，可能会发生瓷砖烧毁事故。我们建议使用磁悬浮技术来减轻推力轴承的负载以避免事故发生。基于不耦合原系统的原理，设计了一种盘式电动磁悬浮电机，它提供法向排斥力作为悬浮力，为轴承抵消一部分轴向载荷，具有自稳性好、重量轻等优点。次要的。同时产生的切向力也无济于事。电气参数和结构参数都会影响两种力。本文研究了解析计算方法、两种力的关系以及气隙中储存和二次消耗的能量。然后得到影响力的参数规律，揭示了提高悬浮力和减小切向力的设计方法。根据理论研究，无芯超导体初级电枢被认为最适合这种具有较高气隙中y轴磁场分量的机器。FEA仿真模型用于验证理论分析。
