Development and dynamic analysis of magnetic levitation flywheel with high-temperature superconducting bearing

本研究提出一种提高高温超导磁轴承永磁部分磁通密度的方法。由于高磁通密度改善了磁轴承的机械特性，因此这一特性变得更加明确。此外，通过高温超导悬浮的钉扎效应，磁轴承成功地实现了吸引型磁悬浮的悬浮方向稳定和排斥型磁悬浮的径向不稳定力的抑制。因此，排斥型磁悬浮曾经是困难的，开发了具有这种高温超导磁轴承的储能飞轮，并阐明了各种特性。

In this study, It have proposed a method of increasing the magnetic flux density of the permanent magnet part that is constructing the high-temperature superconducting magnetic bearing. Since High magnetic flux density improves the mechanical characteristics of the magnetic bearing, this characteristic has clarified.In addition, by pinning effect of high-temperature superconducting levitation, the magnetic bearing has succeeded in levitation direction stabilization of attraction type magnetic levitation and suppression of the radial instability force of repulsive-type magnetic levitation.As this result,repulsive-type magnetic levitation,ever has been difficult, can be realized.Energy storage flywheel with a high-temperature superconducting magnetic bearing like this is developed, and the various characteristics were clarified.
