本发明提供一种两极六槽电机的铁芯分割和接线方式，可应用于最高转速在20000rpm及以上转速的于家用电器、医疗器械、发电及储能设备、化学检测及物质分离设备、无人飞行器上，例如风机、吸尘器、电钻、离心机、发电机、飞轮储能、无人机、航模等。
下面结合图1至图5详细描述根据本发明实施例的电机定子100。
参照图1至图3，根据本发明第一方面实施例的电机定子100，包括：定子铁芯1以及绕组线圈2。
具体而言，定子铁芯1包括定子轭部11和定子齿部12，定子轭部11呈环形，定子齿部12设在定子轭部11的内侧，并且定子齿部12沿定子轭部11的径向延伸，定子轭部11的内侧设有沿周向间隔布置的六个定子齿部12。换言之，定子齿部12包括沿六个，且六个定子齿部12在定子轭部11的周向间隔布置，对应的电机定子100包括六个槽。绕组线圈2缠绕在定子轭部11上，且每两个相邻的定子齿部12之间的定子轭部11上均缠绕有绕组线圈2，相对(例如径向相对)的两个绕组线圈2相互并联并配合为一相，三相绕组线圈首尾相接呈双三角形接线。这样能够降低线反电动势和绕线难度。
其中，绕组线圈2的绕线位置位于定子轭部11，定子铁芯1中两两互相面对的定子轭部11的绕线为一相，例如绕组线圈A和绕组线圈X为一相，两者并联；绕组线圈B和绕组线圈Y为一相，两者并联；绕组线圈C和绕组线圈Z为一相，两者并联，并联后形成的(A\X)、(B\Y)、(C\Z)三组绕线按三角形接线方式首尾连接，共同形成一个双三角形接线方式。
采用双三角形接线方式是因为三角形接线的线反电动势是星形接线的线反电动势的73.2％，对于采用低压电源供电或由电池供电的电机，有利于通过增加绕组线圈2的匝数、减小线径来降低绕线困难。根据电机定子100六槽的这种特殊的结构，将每相绕组线圈各自并联的方法，相对于串联的方法而言又降低了50％的线反电动势，这就更进一步可以增加绕线匝数、减小绕线线径，降低了绕线的困难度，双三角形接线如图2所示、分割铁芯如图1所示。
根据本发明实施例的电机定子100，径向相对的两个绕组线圈2相互并联并配合为一相，三相绕组首尾相接呈双三角形接线。这样能够降低线反电动势和绕线难度。
参照图1，根据本发明的一些具体实施例，定子铁芯1被沿多个定子齿部12中至少一部分的中线位置13分割为至少两瓣(例如，两瓣、三瓣或四瓣等)，定子铁芯1的至少两瓣分别绕线后拼接。由此，通过将定子铁芯1分割两瓣或多瓣，方便绕线。
定子铁芯1的至少两瓣分别绕线后拼接的方式可以为粘接，焊接或卡接等。优选地，定子铁芯1的分割位置在定子齿部12的中线位置13。当然，定子铁芯1的分割位置也可以在定子齿部12的除中线位置13之外的位置，例如，定子铁芯1的分割位置可以在定子齿部12的偏离中线位置13的某处。
如图3和图4所示，根据本发明的一些具体实施例，多个绕组线圈2在定子轭部11上的缠绕方向相同(包括同时正向或反向)。所有相邻定子轭部11的绕组线圈2的绕线方向均一致，分为同时正向一致和同时反向一致。
如图3、4所示，当电机定子100应用在电机200上时，由于采用双三角形接线，当电
机转子210转动时相互对面(径向相对)的两个槽产生的感生反电动势正好方向相反，根据图2所示的双三角形连线的原理，形成如下的连线规则：A、Z、B、X、C、Y等槽轭部绕线，其绕线方向相同，按图3、图4所示，所有1号线头相接、所有2号线头相接、所有3号线头相接。
结合图5，根据本发明的一些具体实施例，多个绕组线圈2中每相邻的两个绕组线圈2在定子轭部11上的缠绕方向相反。采用相邻定子轭部11绕线方向相反的方法绕线，所有相邻定子轭部11的绕组线圈的绕线方向相反。
当电机定子100应用在电机200上时，由于采用双三角形接线，当电机转子210转动时相互对面的两个槽产生的感生反电动势正好方向相同，根据图2所示的双三角形连线的原理，形成如下的连线规则：A、B、C槽轭部绕线，其绕线方向相同；Z、X、Y槽轭部绕线，其绕线方向也相同，但Z、X、Y槽轭部绕线与A、B、C槽轭部绕线的绕线方向相反，按图5所示，所有1号线头相接、所有2号线头相接、所有3号线头相接。
根据本发明的一些具体实施例，每个绕组线圈2在定子轭部11上缠绕的匝数可以在5匝到120匝的范围内。由此，通过调节轴向长度、定子轭部11上绕组线圈2的匝数在5匝至120匝之间为最优绕线匝数范围。
其中，每个绕组线圈2在定子轭部11上缠绕的匝数可以为5匝、15匝、25匝、35匝、45匝、55匝、60匝、70匝、80匝、90匝、100匝、110匝或120匝等。每个绕组线圈2在定子轭部11上缠绕的匝数可以根据实际需要适应性调整。
根据本发明的一些具体实施例，绕组线圈2为双线或多线并绕的方式缠绕在定子轭部11上。每匝绕组线圈2可以由两根线或多跟线一起并绕，这样可以提高绕线效率，改善电机定子100的使用性能。
根据第二方面实施例的电机200，电机200可以为三相永磁无刷电机。电机200包括：电机定子和电机转子210，电机定子为上述的电机定子100，电机转子210设在电机定子100的内侧，并且电机转子210可旋转地设在电机定子100的内侧，其中电机转子210可以为两极转子。由此，通过在电机200上设置上述第一方面实施例的电机定子100，可以提高电机200的使用性能。
其中，电机200的转速在20000rpm以上，电机200可以应用于家用电器、医疗器械、发电及储能设备、化学检测及物质分离设备、无人飞行器上。
进一步地，参照图1以及图3至图5，电机转子210可以包括拼接成环形的两极永磁磁环。电机转子210采用两极永磁磁环结构，容易制备，且磁环容易安装。
更进一步地，电机转子210采用注塑两极永磁磁环结构。电机转子210采用注塑两极永
磁磁环结构，容易制备，且磁环强度高容易安装。
在本发明的一些具体实施例中，电机转子210的外径可以在5毫米到20毫米的范围内。由此，使得电机200的效率比较高，最具经济性，大于此电机转子210外径尺寸不具备经济性。
其中，电机转子210的外径可以为5毫米、10毫米、15毫米或20毫米等。
可选地，电机200可以应用于转速高于每分钟2000转的风机、吸尘器、吹风机、干手机、车床、电钻、离心机中。也就是说，在风机、吸尘器、吹风机、干手机、车床、电钻或离心机等中均可以设有上述的电机200。
