具体实施方式
实施例1：
请参阅图1至图6所示，本实施例提供一种凸极轮毂电机，其包括轮毂本体1、固定于轮毂本体1上的转子铁芯2、与转子铁芯2配合的定子铁芯3以及电机轴4，定子铁芯3通过铁芯支架5与电机轴4固连，轮毂本体1的外侧设置有端盖6，轮毂本体1的内侧设置有毂盖7，端盖6、毂盖7与电机轴4均通过轴承配合，电机轴4上设置有编码器8，毂盖7上设置有与编码器8匹配的磁环9。
其中，转子铁芯2包括多个间隙排列成圆环状的矽钢块10，相邻两个矽钢块10之间夹设有磁钢11，从而形成完整转子环，每个矽钢块10与相邻的磁钢11之间、转子环的外缘与轮毂本体1的内缘之间采用胶体粘接固连，具体采用的胶体为厌氧胶、AB胶或环氧胶中任一种。
定子铁芯3上的绕组采用单线并联方式绕制，以提高定子铜满率。相对于多线串联方式，单线并联方式可以充分利用绕线槽面积，使漆包线铜满率由42.9％提高到52.45％，降低电机内阻，提高输出转矩。
矽钢块10的贴靠轮毂本体1的边沿上设置有增加胶体粘接效果的第一凹槽12，设置为容纳预设量胶体。
每个矽钢块10的靠近定子铁芯3的边沿上设置有第二凹槽13，第二凹槽13可以增加电机凸极率，降低齿槽转矩，还可以做工艺定位槽使用。
每个矽钢块10与磁钢11贴靠的侧沿上设置有凹陷部14，从而与磁钢11间形成隔磁气隙15，此处的凹陷部14位于矽钢块10的贴靠轮毂本体1的侧端，减少漏磁，方便成型，也方便磁钢11装配。
每个矽钢块10的靠近定子铁芯3的侧端设置有对磁钢11限位的凸部16，该凸部16可以降低齿槽转矩，提高电机凸极率，也用于抵制磁钢11在旋转时的离心力。
每个矽钢块10上开设有降低齿槽转矩的通孔17，且通孔17为引导磁路走向设置为三角状。该通孔17改变了磁路走向，提高聚磁能力，减少漏磁，同时有效降低了齿槽转矩，还可作为工艺定位孔使用。
每个矽钢块10由多个矽钢片堆叠而成，每个矽钢片上设置有多个扣点18，相邻矽钢片通过扣点18依次卡扣。此处的扣点18为矩形状，叠压时，上一片矽钢片的扣点18卡合在下一片矽钢片的扣点18内形成自扣，取代原有铆钉定位方式，此结构自扣便捷，相对铆钉定位精度更高。
另外，轮毂本体1上开设有充气口19，充气口19自轮毂本体1的外侧表面延伸至内侧表面，且自外向内包括螺纹孔和锥形孔20，充气口19配合气门嘴21使用，气门嘴21上的头端对应锥形孔20设置为锥部，对应螺纹孔设置有外螺纹，锥部上开设有环形槽，环形槽中嵌入有密封圈22。充气口19的锥度结构与特殊结构的气门嘴21配合，达到密封效果，与常规气门嘴21不同，此结构适应轮辋空间狭小的场合。
实施例2：
请参阅图7至图9所示，本实施例提供一种凸极轮毂电机，在实施例1的基础上，提出另一种转子结构。
此处转子的矽钢块省去了凹陷部14和凸部16，并提高了矽钢块的密布数量，和定子同齿，以此增加磁钢11的使用量，提高永磁体磁通，从而提高电机功率密度，也方便矽钢片冲压成型。
实施例3：
请参阅图10至图12所示，本实施例提供一种凸极轮毂电机，在实施例1 的基础上，提出另一种转子结构。
此处转子的矽钢块于凸部16处开设有第三凹槽23，以降低应力，增强抗应效果，提高电机凸极率。另外，围绕通孔17的周围设置多个圆形的扣点18，定位精度更高。
综上，上述的凸极轮毂电机主要通过优化转子铁芯2的结构及各部件布局，以提高转子凸极率，提高电机功率密度，拓宽电机效率平台，提高车辆续行里程，降低电机齿槽转矩，降低电机整体重量，从而达到提高电机性能的目的。
