电风扇电机定子是电风扇的重要零件之一,通常用硅钢片迭装而成。目前采用的迭装方法是将硅钢片打孔后用铆钉连接或用压力机压装后铸铝连接,这样不但工序复杂,费工耗料,而且因连接截面大,有损于硅钢片间的绝缘效果,从而增加了铁芯的涡流损耗。若采用激光焊接工艺,只需在迭装好的定子外圆面上,根据需要焊接几条轴向焊缝,即可牢固地把硅钢片 Fan Motor Stator is one of the important parts of the fan, usually made of silicon steel laminated. The current method is used to stack the silicon steel sheet pierced with rivets or press after the press-fit aluminum connection, so not only the process complexity, labor consuming materials, but also because of the large cross-section, detrimental to the silicon steel between Insulation effect, thereby increasing the core eddy current loss. If the use of laser welding process, just a good job in the laminated stator outer surface, according to the need to weld several axial welds, you can firmly put the silicon steel sheet
