【摘要】：永磁偏置軸向徑向磁軸承能夠?qū)崿F(xiàn)轉(zhuǎn)子的三自由度懸浮,結(jié)構(gòu)緊湊、功耗低,但3個(gè)自由度之間易耦合。對(duì)一種短轉(zhuǎn)子永磁偏置軸向徑向磁軸承進(jìn)行了研究,它的軸向定子位于徑向定子之上,為短轉(zhuǎn)子結(jié)構(gòu)。根據(jù)二維仿真結(jié)果進(jìn)行等效磁路分析,對(duì)徑向控制磁路進(jìn)行解耦分析,設(shè)計(jì)徑向力為400 N的磁軸承進(jìn)行三維有限元仿真分。并通過(guò)三維網(wǎng)格圖對(duì)軸向徑向懸浮力進(jìn)行耦合分析。研究結(jié)果表明,在平衡位置附近,軸向徑向間彼此解耦,懸浮性能優(yōu)良。
[Abstract]:Permanent magnet bias axial radial magnetic bearing can realize three degrees of freedom suspension of rotor, compact structure, low power consumption, but easy coupling between three degrees of freedom. A kind of short rotor permanent magnet bias axial radial magnetic bearing is studied in this paper. Its axial stator is located above the radial stator and is a short rotor structure. The equivalent magnetic circuit is analyzed according to the two-dimensional simulation results, and the radial control magnetic circuit is decoupled. The magnetic bearing with radial force of 400N is designed and simulated by three-dimensional finite element method. The coupling analysis of axial radial suspension force is carried out by three-dimensional grid diagram. The results show that the axial radial force is decoupled from each other near the equilibrium position. Excellent suspension performance.
