摘要
通过对稀土起重永磁吊研制过程的总结和研究 ,系统地论述了稀土起重永磁吊的设计原理 :①永磁体的回复曲线起始点应位于其退磁曲线的最大磁能积点或其下方 ,以提高吸重比(吸重 /永磁体重量 ) ;②不同性能永磁体应与磁路结构有机配合 ,以降低吸重成本比 (永磁体成本 /吸重 )。
According to the further study of the rare earth lifting permanent magnet and the summary of the industrial prototypes,a systematic design theory has been established in this paper.Two regulations of the design of magnetic circuit are discussed,one is that the lifting permanent magnets beginning work point should lie on the point of the maximum magnetic energy product or a bit lower than that in the degenerative magnet curve,so as to raise the lifting ratio(the weight of attracted body/the weight of permanent magnetic bodies);the other is that the different performance permanent magnetic bodies should adapt to different kinds of magnetic circuits to low the cost ratio(the cost of permanent magnetic bodies/the weight of attracted body).
