附图说明
图1是本发明一种电动车用带制动盘的轮毂电机结构示意图。
具体实施方式
下面结合附图对本发明做进一步的详细说明。
结合附图，一种电动车用带制动盘的轮毂电机，包括车轴1、轮毂2、定子铁心3和车架4，所述轮毂2外表面上固定有防静电保护壳5，所述轮毂2固定于车轴1的末端，所述轮毂2内侧设有固定于车轴1上的制动盘6，所述制动盘6一侧设有永磁体7，所述制动盘6圆周上均布有6个扇形通孔，两个扇形通孔之间有导磁材料制成的导磁肋，所述车轴1通过轴承8连接在车架4上，所述定子铁心3围在制动盘6轴向两侧并且固定在车架4上，相邻子定子铁心3沿圆周方向相差40度，所述每个子定子铁心3的内侧朝向制动盘的两面各带有一个电枢极，电枢极的侧面呈扇形，所述电枢极上绕有电枢绕组9，所述电枢绕组9所在的平面平行于制动盘6，所述车架4上位于没有子定子铁心的位置上固定有制动钳10。
所述车轴1涂有绝缘涂层。
所述定子铁心3上设有励磁绕组11。
所述励磁绕组11绕六个子定子铁心的轭部绕制，沿圆周方向相邻的电枢绕组绕向相同。
所述励磁绕组11绕每个子定子铁心的轭部绕制，相邻励磁绕组11绕向相反，沿圆周方向相邻的电枢绕组绕向相反。
本发明的工作原理：由于本发明的电励磁磁极和电枢极在轴向上对齐，因此当制动盘能导磁的部分与电枢极对齐时，该电枢极匝链的磁阻最小、电枢绕组磁链最大；当制动盘的扇形通孔对齐电枢极时，该电枢极匝链的磁阻最大、电枢绕组磁链最小。当制动盘能导磁的部分逐渐靠近电枢极时，该相电枢绕组与励磁绕组的互感在增加；该相电枢绕组的自感也在增加。当制动盘能导磁的部分脱离电枢极时，该相电枢绕组与励磁绕组的互感在增加；该相电枢绕组的自感也在增加。本发明电机作为电动机运行时，给产生正的感应电动势的一相绕组通以正向电流，则该绕组可以产生正的转矩，使轮毂正转；给产生负的感应电动势的一相绕组通以正向电流，则该绕组可以产生负的转矩，使轮毂反转。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均包含在本发明的保护范围之内。
