摆线针轮减速机:电机交流损耗及槽漏抗分析
发布时间:2018-08-24 23:23:00 点击:    

摆线针轮减速机2018年8月24日讯:在高速永磁无刷电机定子槽中,除了基波磁通漏磁通还有其他高次谐波分量的漏磁通,这些漏磁通的频率都很高,都会在定子绕组中产生较大的涡流损耗,通常不能忽略不计。

式中: μ0 为空气磁导率; N为导体数; leff 为铁心长度; h0 为槽口高度; b0 为槽口宽度。

从式( 8) 可知, Ls-tip和槽口高度成正比,与槽口宽度成反比,因此,槽内的漏磁通也会相似关系,而导体的邻近损耗和磁通密度的平方成正比,所以随着槽口高度增加和槽口宽度减小,绕组的交流损耗会相应增加,且槽宽的影响大于槽高的影响。
