Description
技术领域
本发明涉及一种电机的部件,尤其涉及一种电机定子。
背景技术
电机定子机座常用铸件,如用铸铁,则机座较重,且加工性不好,如用铸铝,则机座刚度和强度欠佳。
电机运行时,带绕组定子铁心产生的热量通过筋条直接传递给机座筒体,因筋条数量有限,造成机座筒体温度分布不均匀,不利电机散热,进而不利电机温升和电机效率,而且机座表面温度高点有时会超过安全温度。所以改善带绕组定子铁心散热效果,使筒体表面温度均匀很有必要。
发明内容
本发明提供了一种电机定子,它的机座为钢板焊接件,力学性能好,制作方便,加工简单。机座筒体下部有进风窗口用来进风冷却带绕组定子铁心,上部有出线窗口用来引出带绕组定子铁心引出线。设有鱼刺形散热套,改善带绕组定子铁心散热效果,使筒体表面温度均匀,降低电机温升,提高电机效率。鱼刺形散热套和带绕组定子铁心采用压装,与机座筋条完全贴合,并且安装方便。
本发明的技术方案:一种电机定子,它包括机座、鱼刺形散热套和带绕组定子铁心,机座包括前法兰、筋条、筒体、后法兰、吊攀和底脚;其结构特点是:前法兰、筋条、筒体、后法兰、吊攀和底脚均为钢板件,筋条为凸形,筋条均布于前法兰和后法兰之间,筒体裹在筋条外,前法兰、筋条、筒体、后法兰焊接在一起,吊攀和底脚焊接在筒体上;筒体下部有进风窗口,上部有出线窗口;鱼刺形散热套为散热性好的铸铝件,压装在机座筋条上;带绕组定子铁心压装在机座筋条上。
本发明的技术效果:1、机座前法兰、筋条、筒体、后法兰、吊攀和底脚均为钢板件,筋条为凸形,筋条均布于前法兰和后法兰之间,筒体裹在筋条外,前法兰、筋条、筒体、后法兰焊接在一起,吊攀和底脚焊接在筒体上。力学性能好,制作方便,加工简单。2、机座筒体下部有进风窗口用来进风冷却带绕组定子铁心,上部有出线窗口用来引出带绕组定子铁心引出线。3、设有散热套,改善带绕组定子铁心散热效果,使筒体表面温度均匀,降低电机温升,提高电机效率。散热套为铸铝件,散热好,制造简单;散热套为鱼刺形,增大了散热面积,风阻小;散热套采用压装的方式,与机座筋条完全贴合,散热好。4、带绕组定子铁心采用压装的方式,与机座筋条完全贴合,散热好。
