Abstract

本实用新型公开了一种电动机定子冲片。该定子冲片是在槽孔上端一体设有弧形槽，在弧形槽的顶部有一圆形收缩孔，冲片可弯折成圆弧形，两层冲片可一正一反叠装。该冲片设计结构合理，能提高产品的质量和性能。

Description

电动机定子冲片
技术领域
本实用新型涉及一种电动机定子冲片，是电动机定子铁芯的一个部件。
背景技术
在现有技术中，电动机定子冲片是从整片表面涂有绝缘或有氧化膜的硅钢片上一次冲压成型，但材料的利用率约50％左右，从而浪费了材料，也增加了电动机的成本。针对上述情况，中国专利ZL943365432，中国专利ZL00228344.1都公开了一种电动机的定子冲片，上述专利在冲片上冲有直槽、并在直槽底部冲压出锥形凸形槽或冲出三角形槽孔，这种结构的定子冲片是节省材料，降低成本，但都存在着冲片铁损大，机械强度低，无法进行实际使用。
发明内容
本实用新型提供一种既能节省原材料，而各项技术指标又能符合电机要求的电动机定子冲片。该定子冲片包括冲片及冲片上的槽孔，其特征在于冲片上的槽孔上端一体设置有弧形槽，在弧形槽的顶部有一圆形收缩孔。这种槽孔上设置带圆孔弧形槽的结构，保证了模具的制造和冲片的成形；同时冲片可一正一反交错叠装减少漏磁，提高了定子的机械强度和导磁率，完全满足了电动机性能的要求。该定子冲片设计合理、提高了产品的质量和性能。
附图说明
图1是本实用新型定子冲片结构示意图。
图2是定子冲片成型效果示意图。
图1、2中，1是冲片，2槽孔，3弧形槽，4收缩孔。
具体实施方式
下面结合附图及实施例对本实用新型作进一步说明：
本实用新型参照附图1制作冲模，采用直线两片对冲，在冲片1上一体冲出槽孔2及槽孔上端的弧形槽3及圆形收缩孔4。将冲出的定子冲片1弯折成圆弧形，效果如附图2的电动机定子片。两定子片可一正一反叠装，装成的定子可减少漏磁。

Claims (2)

1、一种电动机定子冲片包括冲片，冲片上的槽孔，其特征在于：槽孔(2)上端一体设有弧形槽(3)，在弧形槽(3)的顶部有一圆形收缩孔(4)，冲片可弯折成圆弧形。
2、根据权利要求1所述的定子冲片，其特征在于：两层冲片(1)可一正一反叠装。
