Description

大型稀土永磁电机定子铁芯
技术领域
本实用新型涉及电机定子铁芯。
背景技术
传统的工艺是单层芯片、多片铆焊。该工艺具有材料浪费大、劳动强度大、生产速度慢等弊端。环状冲片产品周围的周角料和中间的圆形材料无法使用,成为冲压落料而被浪费,材料利用率不到20%。
实用新型内容
针对上述技术问题,本实用新型的目的在于提供一种大型稀土永磁电机定子铁芯,其结构简单,加工效率高,材料利用率高。
大型稀土永磁电机定子铁芯,其特征在于:包括卷绕成螺旋形状的定子条,定子条焊接整形后成型。
所述的电机定子铁芯,外径尺寸为460mm,内径尺寸为360mm,高度尺寸为95mm。
采用上述结构的电机定子铁芯,其成型后的内、外径与环状冲片的内外径相等,再经焊接、整形、最后成为成品。显而易见,这一技术可避免传统工艺中周角料和中间圆形料的浪费,仅有与嵌线槽相对应的极少量部分成为废料,材料利用率达到70%以上,比旧工艺提高了50%左右。
附图说明
图1为本实用新型的结构示意图:
图2为本实用新型的侧视图:
图3为本实用新型定子条螺旋状示意图。
具体实施方式
如图1、2、3所示,大型稀土永磁电机定子铁芯1,包括卷绕成螺旋形状的定子条2,定子条2焊接整形后成型,所述的电机定子铁芯1,外径尺寸为460mm,内径尺寸为360mm,高度尺寸为95mm。电机定子铁芯1,其成型后的内、外径与环状冲片的内外径相等,再经焊接、整形、最后成为成品。显而易见,这一技术可避免传统工艺中周角料和中间圆形料的浪费,仅有与嵌线槽相对应的极少量部分成为废料,材料利用率达到了70%以上,比旧工艺提高了50%左右。
