下面结合附图并通过具体实施方式来进一步说明本实用新型的技术方案。
如图1、图2及图3所示，一种可直接安装扇叶的吊扇电机，包括转轴1、定子2和转子3，所述定子2容纳在所述转子3的内环腔体310中；还包括用于安装扇叶的扇叶安装部12，所述扇叶安装部12可拆卸地固定在所述转子3，若干所述扇叶呈辐射状均匀分布在所述扇叶安装部12的四周。
电机中，电机的定子绕组做成三相对称星形接法，电机的转子上固定了已充磁的永磁体，在驱动器的作用下，定子电枢各相绕组不断地换相通电，使定子磁场随着转子的位置在不断地变化，使定子磁场与转子永磁磁场始终保持左右的空间角，产生转矩推动转子旋转，转子转动，将电能转化为机械能，则为了保证转子的平稳转动，转轴将定子和转子连接时，定子和转子之间的同轴度必须极高。
本技术方案中，直接将用于固定扇叶的扇叶安装部12固定在转子3上，转子3转动时，直接带动扇叶转动，而无需重新设置其他外壳安装扇叶，简化安装工序；相比通过外壳安装扇叶，通过带动外壳转动从而带动扇叶转动，本技术方案中的扇叶直接被转子3带动，则驱动装置的能量无需再耗费在外壳等附属配件上，降低了能耗输出。
扇叶安装部12可拆卸地固定在所述转子3，则只需根据客户要求生产有要求数量扇叶安装位的扇叶安装部12即可，再将扇叶安装部12安装到转子3即可，不同客户的不同要求，无需改变除扇叶安装部12外的任何装置结构(可量产)，只需更换模具生产可安装要求数量扇叶的扇叶安装部12即可，无论是设置3片、4片和5片扇叶的结构均可，且安装使用精度高，转子3平稳转动的同
时简化了加工工序，大大地节约了成本。
另外，本技术方案中，扇叶通过扇叶安装部12直接安装到转子3，而直接被转子带着旋转，结构简单，紧凑；则为了扩展吊扇的功能，可在吊扇通过设置不旋转的外壳，在外壳上按照场合需要，安装漂亮的灯体结构、摄像装置、香薰发散装置等，满足基本扇风使用的同时，获得照明、摄像、清新空气等功能，这样一款多功能吊扇安装在房间里，提高了整个房间的格调和品味，也更能适应需求不断多样化的市场，适宜大力推广。
如图1及图4所示，所述磁瓦固定部31的外侧壁设有安装楞9或安装槽10，对应的，所述扇叶安装部12的内侧设有安装槽10或安装楞311，所述安装楞311卡装到或脱离所述安装槽10，使得所述扇叶安装部12可拆卸地套装在所述转子3。
本实施例中，若干所述安装楞9均匀分布设置在转子3的外侧，对应的，所述扇叶安装部12均匀分布设置在转子3的内侧，拆装时，直接将安装楞9卡装或拆离安装槽10即可，固定时稳定，拆装时操作方便。
如图4所示，所述磁瓦固定部31的下端面设有支撑部11，所述支撑部11由所述磁瓦固定部31的下侧面沿径向向外侧延伸形成，所述扇叶安装部12固定在所述转子3时，所述扇叶安装部12的下端面与所述支撑部11的上端面接触。
所述磁瓦固定部31的下侧面沿径向向外侧延伸形成支撑部11，则所述安装槽10垂直于所述支撑部11的上端面；所述转子3带着扇叶安装部12高速旋转时，支撑部11阻隔了磁瓦固定部31向下运动，而避免了磁瓦固定部31带着扇叶与转子3脱离的问题，提高了扇叶运行的稳定性。
优选的，所述扇叶安装部12由环状结构和扇叶安装块组成，且扇叶安装位
为空腔结构，所述空腔结构内设有若干安装柱121，所述安装柱121设有螺纹；扇叶安装块为空腔结构，减轻了转子3整体的重量，降低了能耗输出；而设置安装柱121，采用从下往上或从上往下将紧固螺丝依次穿过扇叶、安装柱121的内螺纹的连接方式将扇叶安装固定在扇叶安装块上，固定稳定，避免扇叶高速旋转时，紧固螺丝从螺纹孔内松出，而扇叶从扇叶安装部12上被甩出。
所述转子3包括磁瓦固定部31和轴承安装部32，所述磁瓦固定部31与轴承安装部32为一体化制成，且所述轴承安装部32仅设置在所述磁瓦固定部31的旋转平面的一侧，所述转轴1、定子2、磁瓦固定部31和轴承安装部32的几何中心在一条直线上。
本实施例中，所述磁瓦固定部31为环状结构，环状结构的内侧壁均布有若干磁瓦6，若干磁瓦6环绕所述磁瓦固定部31的中心设置，磁瓦6与磁瓦6之间的环状结构设有定位安装槽311，如图6所示，所述定位安装槽311由所述环状结构的内侧壁向所述磁瓦固定部31的外侧凹陷形成，长度与所述环状结构的高度相当，且所述定位安装槽311的上下两端分别与所述环状结构的上下两个端面连通，上述结构的定位安装槽311在所述转子3一体成型时形成，在成型模具上对应于定位安装槽311的位置配合的是定位楞，磁瓦6放置在相邻两定位楞之间，方便定位，从而提高了装配的精度。
本技术方案中，所述磁瓦固定部31与轴承安装部32采用注塑或金属压铸工艺成型一体化制成，且轴承安装部32仅设置在磁瓦固定部31旋转平面的一侧，则两者的同轴度通过成型模具精准保证；安装时，先在轴承安装部32内安装好轴承8，继而将固定了定子2的转轴1穿过所述磁瓦固定部31的内环腔体310后穿入所述轴承安装部32并固定，使得转轴1、定子2、磁瓦固定部31和轴承安装部32的几何中心处于同一直线上即可，安装方便，通过成型模具和调
节工艺参数，利用成熟的注塑或金属压铸设备及工艺，保证了磁瓦固定部31和轴承安装部32之间的同轴度和各自的对称性即可，工艺步骤简单，产品的尺寸精度高，降低了成本。
所述转子3还包括连接部33，所述连接部33的一端固定在所述磁瓦固定部31，另一端固定在所述轴承安装部32，使得所述磁瓦固定部31与所述轴承安装部32不直接接触，所述磁瓦固定部31、轴承安装部32和连接部33为一体化成型制成。
定子2固定在转轴1上，通电后使得转子3通过轴承安装部32内的轴承绕着转轴1旋转，连接部33实现磁瓦固定部31与轴承安装部32不直接接触的连接，保证转子的平稳旋转。
所述连接部33为L状加强筋，所述L状加强筋的一端固定在所述磁瓦固定部31，另一端固定在所述轴承安装部32。
L状加强筋，固定时一条边与转轴1平行，另一条边与转轴1垂直；与转轴1垂直的边的末端固定在磁瓦固定部31，与转轴1平行的边的末端固定在轴承安装部32上；若干所述L状加强筋均匀分布固定在所述磁瓦固定部31的四周，保证磁瓦固定部31和轴承安装部32之间的稳定连接。
如图2及图6所示，所述L状加强筋与轴承安装部32的连接处设有第一加强筋4，所述第一加强筋4的相邻两个侧面中，一个侧面固定在所述轴承安装部32，另一个侧面固定在所述L状加强筋；所述L状加强筋中两条边的交汇处设有第二加强筋5，所述第二加强筋5的相邻两个侧面分别固定在所述L状加强筋的两条边。
两个不同形状构件的连接过渡位置为强度较弱的位置，本技术方案中，仅在转子3的一侧设置轴承安装部32，再通过若干L状加强筋连接固定磁瓦固定
部31和轴承安装部32，为进一步保证转子3转动时所需的支撑强度，故而设置第一加强筋4以加强L状加强筋与所述轴承安装部32之间的连接强度，设置第二加强筋5以加强L状加强筋中两条边的连接强度，从而保证转子3在高速转动时，转子3的各部分结构能保持足够的强度。
所述轴承安装部32内叠加设置有一个以上轴承，所述轴承安装部32设有内径不相等的阶梯状安装腔体。
增加所述轴承安装部32在转轴1轴向上的长度，使得所述轴承安装部32内能容纳一个以上轴承，通过两个或更多同轴安装的轴承，保证转轴1与转子3之间的稳定安装，以满足转子3高速运转所需的强度。
不同外径的轴承安装在内径不相等的阶梯状安装腔体内，而安装腔体内，不同内径之间过渡时的环状侧壁，给外径较小的轴承提供了支承力，也避免了各轴承在轴向上的整体滑动，提高装配精度，保证转子3的平稳转动。
优选的，如图2及图7所示，所述定子2包括定子本体21、定子齿22、绕组23和若干弧形片24，所述转轴1穿过所述定子本体21后两者固定，所述定子齿22呈放射状均匀分布在所述定子本体21的边缘，相邻所述定子齿22之间形成线槽，所述绕组23缠绕设置在所述定子齿22；
所述弧形片24的弧形向外侧凸出，且固定在所述定子齿22的齿根部内侧，并垂直于所述定子本体21的端面设置；若干所述弧形片24均匀分布在定子本体21的端面上，组成环绕所述转轴1的圆形。
根据定子和转子相互作用的原理，需要在各定子齿22分别进行绕组23，且同一条漆包线，在一个定子齿22上完成绕组后，需要将漆包线的自由端拉到与之间隔两个定子齿后的定子齿上继续缠绕；而弧形片24的设置，作用在于，将漆包线的自由端拉到与之间隔两个定子齿的过程中，漆包线贴附这弧形片24的
外侧弧面行走，相比于将漆包线直线拉到对应位置，通过弧形片24的外侧弧面行走，顺应了各定子齿22之间设置的弧形，漆包线不容易被扯断，提高了饶线效率。
如图5及图8所示，所述转轴1的外侧壁设有内凹槽101，所述内凹槽101由所述转轴1的外侧壁沿径向向内凹陷形成；所述转轴1依次插入所述轴承安装部32和定子2后，将定位环7卡装在所述内凹槽101内，从而将所述定子2和/或轴承安装部32固定在所述转轴1。
如图6所示，所述定位环7为设有开放口的弹性环，且开放口处的定位环两端分别沿着其径向向外侧延伸，形成定位块71；将定位环7卡装在所述内凹槽101内时，定位环7的外侧边缘大于所述转轴1的外径。内凹槽101根据转轴1和定子2、转轴1与轴承安装座32的具体安装位置设定：所述转轴1依次插入所述轴承安装部32和定子2后，一内凹槽101刚好在所述定子2的端面下方，一内凹槽101刚好在所述轴承安装部32的端面下方，将两定位环7分别卡装在两所述内凹槽101后，一定位环7的上端面、定位块71都与定子2的下端面接触，另一定位环7的上端面，定位块71都与轴承安装座32的下端面接触，从而实现轴承安装部32(转子3)、定子2分别与转轴1之间的定位，使得轴承安装部32(转子3)和定子2不会向下运动，装卡方便，定位准确。优选的，同时在轴承安装部32和定子2的下方设置内凹槽101，卡装定位环7后，则两个定位环7和轴承安装部32、定子2的共同作用，限定了转轴1在轴向上的来回运动，保证了定子2和转子3的稳定准确装配，吊扇使用时，性能更稳定。
