结果表明 :实心磁铁推力磁轴承存在最佳工作点 ,影响轴承承载力 温升特性的主要因素是静态气隙和绕组安匝数 ,且对静态气隙更敏感。

• The results indicate that there must be optimal operating point of thrust magnetic bearing with massive magnet. The main effecting factors of carrying capacity temperature rise characteristic involve static gap and/or ampere turns.
