如图2至图10所示，本实施例提供的是一种条形定子，包括条形定子铁芯1和端部绝缘2，条形定子铁芯2包括若干个相互连接的定子铁芯单元10，定子铁芯单元10包括轭部11和从轭部11内侧凸出的齿部12，相邻两个齿部12之间形成嵌线槽13，相邻两个定子铁芯单元10由连接部连接，连接部包括位于所述轭部11外侧的连接筋14，连接筋14底部设有中心孔15，相邻两个铁芯单元10的轭部11于中心孔15两侧形成左切边16和右切边17，左切边16和右切边17之间形成V型槽18，所述端部绝缘2包括若干个端部绝缘单元20，端部绝缘单元20嵌套在定子铁芯单元10上，端部绝缘单元20包括绝缘轭部21和绝缘 齿部22，其中，相邻两个绝缘轭部21之间由V型挡块23连接，所述V型挡块23遮挡所述V型槽18，当条形定子卷圆时左切边16和右切边17贴合，V型挡块23收拢并向所述嵌线槽13凸出。
通过在相邻两个所述端部绝缘单元20之间加设V型挡块23，V型挡块23遮挡所述V型槽18，防止了条形定子绕线时漆包线进入V型槽18内；条形定子卷圆时V型挡块23收拢并向所述嵌线槽13凸出，增强了两个定子铁芯单体10啮合位置的耐压性，减少了添加绝缘胶布的工序，节约生产成本。
上述所述V型挡块23包括左挡块231和右挡块232，左挡块231底部与右挡块232底部连接，所述左挡块231顶部从所述绝缘轭部21内侧面的端部凸出，所述右挡块232从相邻绝缘轭部21内侧面的端部凸出。结构简单。
上述所述条形定子铁芯和端部绝缘注塑一体成型，方便批量生产。
上述所述左挡块231和右挡块232的宽度为0.3～1.0mm。
上述所述定子铁芯展开时，所述左挡块231与右挡块232之间的内夹角α≤170°。
上述所述绝缘轭部21两侧凸出有第一凸台24、第二凸台25和第三凸台26，第一凸台24位于绝缘齿部22上方，第二凸台25位于所述左挡块231顶部，第三凸台26位于所述右挡块232顶部，第一凸台24、第二凸台25和第三凸台26上方形成过线槽27。过线槽27方便过桥线定位。
实施例二：
在实施例一的基础上可以进一步做出改进：解决由于定子铁芯在塑封或安装时定位不方便，使电机在性能上存在较大的个体差异。
如图10至图17、图21所示，所述端部绝缘2还包括若干定位筋24，所述定位筋24凸出于所述轭部11的外侧面111且与所述绝缘轭部21连接，定位筋24外侧设有轴向倾斜面241。所述定子铁芯1、所述端部绝缘2和所述线圈绕组9外包围有外壳塑封体4，所述轴向倾斜面241露出在外壳塑封体4外，所述轴 向倾斜面241的倾斜角大于或等于1°，所述绝缘轭部21的一侧设有接线台211，接线台211轴向方向上设有三个用于安装接线片的接线槽212，接线槽212底部设有凹槽213，所述线圈绕组3的线头穿过凹槽213与接线槽212内的接线片31连接，所述轴向倾斜面241背向所述接线台211设置，所述线圈绕组3包括三组绕组，每组绕组的线头与一个接线片31连接，三个所述接线片31分别安装在一个端部绝缘单元20的接线槽212内，所述外壳塑封体4外表面设有定位槽41，定位槽41的开口42贯穿定位槽41顶部和一侧部，所述定位筋24露出在定位槽41内，所述轴向倾斜面241朝向所述开口42设置。
实施例三：
如图2至图20所示，一种定子组件的制造方法，其特征在于，包括：
端部绝缘注塑：将条形定子铁芯1放入注塑模具中，在条形定子铁芯1外注塑形成端部绝缘2；
绕线：把三相线圈绕组3卷绕安装在所述绝缘齿部22上；
接线：将三相线圈绕组的线头与接线片31连接，选任意一个定子铁芯单元为定位单元，将三个接线片31安装在定位单元的接线槽212内；
装模：将定子组件并放入塑封模具的环形型腔8中，所述环形型腔8的外圆侧壁81设有轴向倾斜的定位面811，使所述齿部12的底部贴合所述环形型腔8的内圆侧壁82，且所述轴向倾斜面241与定位面811贴合；
