推力磁力轴承可以调节转子轴的轴向位移，已被用于高速旋转。然而，传统的推力磁力轴承由于其本身的盘形转子较大，在制造和装配方面存在很多问题。因此，我们提出了一种无需大型盘式转子的推力磁力轴承的新颖结构。所提出的推力磁力轴承采用直径小且形状简单的圆柱形转子。本文介绍了所提出的推力磁力轴承的结构和原理。此外，高速运转实验表明，所提出的推力磁力轴承具有足够的性能以供实际使用。
Thrust magnetic bearings, which can regulate axial displacement of a rotor shaft, have been used for high-speed rotation. However, conventional thrust magnetic bearings have many problems in manufacturing and assembling caused by a large disk rotor of itself. Therefore, we have proposed a novel structure of a thrust magnetic bearing without the large disk rotor. A cylindrical rotor, that has a small diameter as well as a simple shape, is used in the proposed thrust magnetic bearing. This paper introduces the structure and the principle of the proposed thrust magnetic bearing. In addition, it is shown with experiments on high-speed operation that the proposed thrust magnetic bearing is equipped with the sufficient performance in order to make for practical use.
