Description

电机电枢及其绕线方法和电机 技术领域
本申请涉及电机技术领域，尤其涉及一种电机电枢及其绕线方法和电机。
 背景技术
电机包括定子和转子，其中定子和转子均包括电机电枢。一般地，电机电枢包括铁芯与绕组，铁芯通常包括具有中空内孔的轭部以及沿轭部的外表面或内表面周向设置的齿部，绕组包括绕制在齿部上的若干个线圈以及用于连接相邻两个线圈的过桥线，过桥线沿着绕组的绕制方向放置在轭部的端面，为了支撑和固定过桥线，往往在轭部的端面凸设有端子。
随着各种电子产品的轻薄化发展，会考虑省去轭部端面上的端子以降低定子和转子的高度，但是这样一来，直接放置在轭部端面的过桥线变得相对松散且占用端面区域，给电机电枢的工艺定位以及支撑等带来诸多不便。
因此，有必要提供一种新的技术方案以解决上述电机电枢在铁芯轭部无端子的时下存在的技术问题。

优选地，每个所述齿头都具有背对所述齿本体的端部，所述端部呈曲面，所有所述齿头的曲面围合形成一个圆柱面，且所述圆柱面的中心轴与所述中空内孔的中心轴重合。
本申请的目的之二在于提供一种电机，包括转子和用于驱动所述转子转动的定子，所述转子和所述定子中的至少一者采用上述电机电枢。
本申请的目的之三在于提供一种电机电枢的绕线方法。
该绕线方法包括以下步骤：
步骤S01、提供所述铁芯；
步骤S02、在所述铁芯之一个所述绕线齿上绕制形成一个所述线圈；

具体地，齿部102包括至少两个绕线齿10201和由一个或两个以上跨越齿10202形成的跨越齿组，其中，绕线齿10201用于供导线在其上绕制以形成环绕在其上的线圈201，每个跨越齿组设置于相邻两个绕线齿10201之间，齿部102结构同时满足以下三个条件：绕线齿10201和相邻的跨越齿组之间间隔设置、跨越齿组中的每一个跨越齿10202之间间隔设置。过桥线 202至少包括一个第一跨线部2021，第一跨线部2021包括第一跨线段20211、第二跨线段20212和第三跨线段20213，并且第一跨线段20211、第二跨线段20212和第三跨线段20213依次连接，其中，第二跨线段20212沿第二端面111延伸于一个跨越齿10202上，第一跨线段20211从第二跨线段20212的一端朝向第一端面110倾斜延伸，第三跨线段20213从第二跨线段20212的另一端朝向第一端面110倾斜延伸。
在实际应用中，过桥线202至少包括一个第一跨线部2021和一个第二跨线部2022，其中，第一跨线段20211从第二跨线段20212的一端朝向第一端面110倾斜延伸至一个线圈201，第三跨线段20213从第二跨线段20212的另一端朝向第一端面110倾斜延伸至第二跨线部2022，第二跨线部2022沿第一端面110延伸连接于第三跨线段20213与另一个线圈201之间。
请参阅图3、图4，每个线圈201的进线端2011都设置在线圈201靠近轭部101的一端，同时，每个线圈201的出线端2012也都设置在线圈201靠近轭部101的一端；第一引线203与绕组20之第一个线圈201的进线端2011连接，第二引线204与绕组20之最后一个线圈201的出线端2012连接。本实施例中，除了绕组20的第一个线圈201进线端2011与第一引线203连接，最后一个线圈201的出线端2012与第二引线204连接，绕组20中其余线圈201的进线端2011和出线端2012均靠近轭部101设置，这样可以使得过桥线 202尽可能靠近轭部101的边缘，以尽可能减少过桥线 202对铁芯10端面区域（包括第一端面110和第二端面111）的占用。
请参阅图图3，轭部101为具有中空内孔 200的圆环状结构，轭部101具有内表面112和外表面113，其中内表面112朝向中空内孔 200，外表面113则与内表面112相背对，齿部102沿轭部101的周向凸设于外表面113，或者齿部102沿轭部101的周向凸设于内表面112。
在实际应用中，齿部102包括齿本体1021和齿头1022，齿本体1021自轭部101的内表面112朝向中空内孔 200的中心延伸设置，齿头1022设置在齿本体1021之远离轭部101的端部；或者，齿本体1021自轭部101的外表面113朝远离中空内孔 200的方向延伸设置，齿头1022设置在齿本体1021之远离轭部101的端部。
每个齿头1022都具有背对齿本体1021的端部10220，端部10220呈曲面，所有齿头1022的曲面围合形成一个圆柱面，并且圆柱面的中心轴与中空内孔 200的中心轴重合。
请参阅图1~图4及图5，本申请实施例在提供上述电机电枢100的基础上，还进一步提供一种电机300。
电机300包括转子301和定子302，定子302用于驱动转子301转动，定子302和转子301的位置关系和连接关系与目前市面上可接触的电机300相同，在此不再展开赘述，其中，转子301和定子302都包括电机电枢，转子301的电机电枢为上述的电机电枢100，或者，转子301的电机电枢为上述的电机电枢100，或者，转子301和定子302的电机电枢都为上述的电机电枢100。
请参阅图6，本申请实施例在提供电机电枢100以及电机300的基础上，还进一步提供上述电机电枢100的绕线方法，包括以下步骤：
步骤S01、提供电机电枢100的铁芯10；
步骤S02、在铁芯10之一个绕线齿10201上绕制形成一个线圈201；
步骤S03、在跨越齿组上绕制形成过桥线 202；
步骤S04、在相邻的绕线齿10201上绕制形成一个线圈201。
其中，在步骤S02中，还包括在一个线圈201的进线端2011形成第一引线203，以及在另一个线圈201的出线端2012形成第二引线204。
步骤S03中，过桥线 202的绕制步骤包括以下步骤：
从一个线圈201朝向跨越齿组倾斜延伸形成第一跨线段20211；
从第一跨线段20211沿第二端面111在跨线齿组上延伸形成第二跨线段20212；
从第二跨线段20212朝向跨越齿组倾斜延伸至第一端面110形成第三跨线段20213；由第一跨线段20211、第二跨线段20212及第三跨线段20213组成第一跨线部2021；
从第三跨线段20213段朝向相邻的一个线圈201延伸并与线圈201连接形成第二跨线部2022。
如果铁芯10只包括两个绕线齿10201和设置在两个绕线齿10201之间的一个跨越齿组（包括一个或两个跨越齿10202），那么电机电枢100的绕线过程至步骤S04即可结束，如果铁芯10包括三个或者三个以上的绕线齿10201，那么重复步骤S02~步骤S04，直至在沿着绕组20之绕线方向的最后一个绕线齿10201绕制得到最后一个线圈201为止。
以上所述仅是本申请的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本申请创造构思的前提下，还可以做出改进，但这些均属于本申请的保护范围。
