摘要

本文提出了一种新型被动磁轴承系统，该系统能够在与专用定子的短距离内进行无接触旋转。磁悬浮是由位于环形定子和转子上的两组永磁体之间的排斥力保证的。定子磁铁被导电片包围着。由于转子磁体和导电片之间的相对运动而产生的涡流的存在可以克服系统固有的不稳定性。将确定稳定力与角速度的关系，以及悬浮力、磁阻力和稳定涡流在导体片上耗散的功率。

Passively stabilized magnetic bearings

This paper presents a new passive magnetic bearing system that is capable to rotate without contact at a short distance from a dedicated stator. The magnetic suspension is assured by the repulsion between two arrangements of permanent magnets located both on toroidal shaped stator and rotor. The stator magnets are surrounded by a conductive sheet. The presence of eddy currents due to the relative motion between the rotor magnets and the conductive sheet allows overcoming the intrinsic instability of the system. The dependence of the stabilizing force on the angular velocity will be determined as well as the levitation force, the magnetic drag force and the power dissipated in the conductor sheet by the stabilizing eddy currents.
