永磁悬浮回转系统的回转特性研究

摘要

Rotary characteristic research and analysis of permanent magnetic suspension and rotation system is carried out.The structure of permanent magnetic suspension and rotation system and spinning principle of iron ball is introduced, and based on this,magnetic field characteristic of the rotational disk magnet and magnetization characteristic on the surface of iron ball are verified by experiments.Disk magnets are arranged in three different ways,through the comparison and analysis of the rotation speed of the ball,the influencing factors of the rotary characteristic is validated to get the optimal way from permanent magnets arrangements.The research and result can provide the theoretical basis and reference for the further experiment of permanent magnetic suspension and rotation system.%针对一种永磁悬浮回转系统的回转特性进行分析.介绍了永磁悬浮回转系统的结构和铁球的回转原理,并在此基础上用实验验证回转的盘状永磁铁的磁场特性和铁球表面的磁化特性.将盘状永磁铁布置成三种不同的方式,通过对比分析铁球的回转速度来验证影响其回转特性的因素,以得到永磁铁的相对最优布置方式.上述研究及结果为永磁悬浮回转系统的进一步实验验证提供理论基础及参考.
