Abstract
本发明提供了电动机、叠片铁芯及其制造方法，其中，所述制造方法在增材制造打印装置中执行，其中，包括如下步骤：S1，在增材制造打印装置中通入惰性气体，在所述增材制造打印装置中的成型缸中铺硅钢金属颗粒，对所述硅钢金属颗粒进行激光扫描，使得所述硅钢金属颗粒逐层融化为至少一层硅钢金属层；S2，在所述增材制造打印装置中的成型缸中持续铺硅钢金属颗粒，停止对所述硅钢金属颗粒进行激光扫描或者减小执行所述激光扫描的激光功率，使得所述硅钢金属颗粒不完全融化并形成绝缘层，交替执行步骤S1和S2，直至形成具有复数个交替的硅钢金属层和所述绝缘层结构的叠片铁芯。本发明制造方法简便，能形成结构复杂的叠片铁芯，并进一步减少涡流损耗。
