Description

套圈式绕组内外转子无槽电机
技术领域：本发明要求保护的技术方案，属于电机领域。
背景技术：传统电机，如无刷电机，其绕组线圈为梭形结构，绕组线圈两端无效连结边均为两条斜边组成，线圈内宽大，致使传统无刷电机上的绕组线圈的总电阻无法降低。从而大大影响着电机的性能，普遍存在低速转矩不足，效率低，运行不稳定等现象。
发明内容：本发明的目的就是针对现有技术的不足，提供一种低速性能好，效率高的新型电机。改变传统的有槽铁芯为无槽铁芯，绕组线圈直接套圈在铁芯上，其内、外圆分别对应着内、外磁钢和内、外磁轭，并共同组成一套完整的电磁感应回路，内、外磁钢和内外磁轭及转轴通过螺钉与连接板相连组成转子，在轴承座中旋转，铁芯则通过定位座把合上轴承座后组成定子。本发明通过无槽结构，使电机的转矩一转速特性得到改善，使其变硬，通过套圈式绕组及内、外转子的同时采用，大大地提高了线圈的有效感应长度的比例，有效地降低了绕组的电阻，从而大大地提高了低速运行时的效率及输出功率，具有功率体积比大，调速范围宽，低速性能好，效率高等优点。特别适合于对电机要求调速范围，低速转矩大，效率高，体积小的驱动控制场合，如直驱式多功能洗衣机，电动自行车等。
附图说明：图1、本发明的截面图。
          图2、线圈铁芯的剖面图。
          图3、套圈式线圈同传统线圈结构比较图。
具体实施方式：对照图1、图2得知，本发明的铁芯1是无槽结构，绕组线圈2套圈在铁芯1上，铁芯1为分瓣式结构。由三块弧形铁芯16组合而成，这样做不仅方便套入线圈，同时还大大地简化了铁芯的结构，降低成本。每个铁芯上设有一个空档3并通过螺钉6与定位座4、定位板5进行定位，定位座4通过螺钉15把合上轴承座14，形成定子。图2中画出的是16极三相线圈中的一相，A端为首端，X端为末端，从首端到末端各线圈绕制方向为正、反绕相继进行。通过过桥线7连接，而16极电机只采用15个线圈，因是三相星形连接，二相通电，所缺少的那线圈所对应的功率由另一相的一个对应圈来完成，套在铁芯1上的绕组线圈2，其内外圆分别对应着内、外磁钢8、9及内、外磁轭10、11共同组成了一套完整的电磁感应回路。内、外磁钢8、9和内外磁轭10、11转轴12分别通过螺钉与连接板13相连接组成转子，在轴承座14中旋转。
由图3可知，由于铁芯结构的不一样(传统铁芯有槽，本发明则无槽)以及线圈的绕法不一样，造成绕组线圈的结构不同，传统线圈的内部宽度h比本发明线圈的内部宽度h’要大。特别是少极数时尤为突出，这使得传统线圈的无效连结边变长。另外，传统线圈通常为梭形结构，两端的无效连结边均为两条斜边组成，这无疑会大大增加线圈无效连结边的长度，使得传统无刷永磁直流电机的绕组线圈的电阻无法降低，从而大大影响着电机的性能。
