具体实施方式
为了使本公开所属技术领域中的技术人员更清楚地理解本公开，下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开的一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
大中空环形电机的输出方式不同于常规有轴电机的通过转轴进行扭矩输出的输出方式。在大中空环形电机中，未采用传统的转轴和常规的双轴承的支撑方案，因此对转子支撑较为困难。同时大中空环形电机的厚度比较小，导致大中空环形电机的定子的刚度较差。
相关技术中，大中空环形电机的定子采用每层扇形铁芯拼接进而多层扇形铁芯叠压而形成。在每层扇形铁芯中，将扇形铁芯拼接，以最终拼接成一个整圆的铁芯，然后多层整圆的铁芯互相叠压并使得相邻的整圆的铁芯中的扇形铁芯的拼接缝隙不在同一位置，以形成定子铁芯。拼接和叠压形成整圆的定子铁芯后，将定子绕组采用分布式绕组形式布置，即定子绕组跨越不同扇形铁芯，以将整个定子在圆周上固定成一个整体。
如果采用相关技术中的设计制造方案，电机定子会产生较大的变形，进而影响电机的成本、性能和可靠性。
基于上述技术问题，本公开提供一种定子模块、电机和电器设备，旨在至少一定程度上降低大中空环形电机的制造成本，并提高其可靠性。
图1示出了依据本公开一些实施例的定子模块的结构示意图，图2示出了图1中的定子模块的配置有齿的定子铁芯的结构示意图。结合图1以及图2，该定子模块2包括定子铁芯21和定子绕组22，定子铁芯21的内侧间隔设置有两个以上的齿24，定子绕组22和齿24对应设置，定子绕组22套装于对应的齿24上，每个定子模块2的多个定子绕组22串联，以形成模块绕组。
本公开所提供的定子模块2，由于定子模块2的定子绕组22套装于对应的齿24上，多个定子绕组22串联以形成模块绕组，该定子模块2的模块绕组接线后，即可向与其配合的转子模块输出扭矩。即该定子模块可以独立制造组装，再整体装配至电机上接线即可，从而避免定子模块在装配上电机后，再将定子模块上的定子绕组装配接线等操作。由此依据本公开一些实施例的定子模块2结构简单，因此能够节约装配程序，避免出错，以降低成本，提高可靠性。
在一些实施例中，定子模块2中的齿24可以一体成型于定子铁芯21上，这样在方便定子铁芯21和齿24制造的情况下，还可以使定子铁芯21和齿24具有足够的刚度和连接强度，即使在定子模块2的厚度很小的情况下，也能保证定子具有足够的刚度和连接强度。另外，齿24和定子铁芯21可以为通过冲片成型获得的结构，材料利用率高，且具有刚度高、工艺性好的特点，能适用于不同尺寸规格的电机。
在其他实施例中，定子模块2中的齿24也可以焊接或者插接于定子铁芯21上，在此不做限制。
结合图1以及图2，定子模块2还可以包括限位块23，限位块23可以采用环氧玻璃布板等绝缘的复合材料制成，相邻的两个齿24之间均设置有限位块23，以使定子绕组22的两端分别通过定子铁芯21和限位块23限位，以限制定子绕组22，以防止定子绕组22从对应的齿24上脱落。在一些实施例中，齿24的侧部设置有定位槽25，定位槽25可以设置于相邻的两个齿24的相对的侧部，限位块23的端部连接于定位槽25中，该定位槽25可以为V形，限位块23的端部和该定位槽25相匹配，装配时，可以先在定位槽25内涂抹胶水，再将限位块23插入到对应的定位槽25中，以提高限位块23在对应的定位槽25内的连接的可靠性。在其他实施例中，限位块23的端部也可以焊接或粘接在齿24的端部，在此不做限制。
定子绕组22是根据电磁方案确定的线径和匝数绕制而成的同心绕组，装配定子绕组22时，可以先在定子铁芯21的齿24与定子绕组22之间放置绝缘材料，例如绝缘槽纸NHN或者绝缘材料制成的线架等。每个定子模块2的多个定子绕组22串联形成模块绕组后，并分别引出U、V、W接线头，后续备用。接线完毕后，整体真空压力浸绝缘漆。在一些实施例中，多个定子模块2的模块绕组可以并联或者串联，具体可根据电机的输出功率做相应设置即可，在此不做限制。
图3示出了具有图1所示的定子模块的电机的结构示意图。本公开的电机包括机座1和上述定子模块2。定子模块2设置有至少一个，至少一个定子模块2连接在机座1上。
对于本公开所提供的电机，由于其中的定子模块2的定子绕组22套装于对应的齿24上，多个定子绕组22串联以形成模块绕组，该定子模块2的模块绕组接线后，即可向与其配合的转子模块输出扭矩。即该定子模块可以独立制造组装，再整体装配至电机上接线即可，从而避免定子模块在装配上电机后，再将定子模块上的定子绕组装配接线等操作。由此依据本公开一些实施例的定子模块2结构简单，因此能够节约装配程序，避免出错，以降低成本，提高可靠性。
在一些实施例中，定子模块2可以设置有多个。多个定子模块2绕机座1的周向依次连接在机座1上，以形成一个第一环形结构。在安装定子模块2时，可以先将待装配的定子模块2制造完毕后，再将多个定子模块2装配在机座1上即可，不必再将定子绕组跨接在相邻的电子模块上的齿上。由此依据本公开一些实施例的定子模块2结构简单，从而能够避免出错，以降低成本，提高可靠性。在其他实施例中，定子模块2也可以只设置有一个，该定子模块2接线后，即可向与其配合的转子模块输出扭矩。
结合图1-图3，定子铁芯21可以呈扇形，相邻的定子铁芯21的端部对接，以拼成上述第一环形结构，以避免采用压装过程中相邻的定子铁芯21采用互相叠压方式的装配方式，以提高定子铁芯21的利用率。
需要说明的是，本申请的定子模块2可以采用12槽10极的极槽配合数，也可以采用12槽8极、9槽6极等其它极槽配合方式，在此不做限制。相应地，可以采用七个定子模块2并联工作，组成整个电机方案，也可以采用六个、八个等其它更多或更少的定子模块2，以拼装成一个电机，在此不做赘述。
图4示出了图1中定子模块的轴承的结构示意图，图5示出了依据本公开一些实施例的定子模块的俯视示意图，图6示出了沿图5中的线A-A截取的剖面示意图。结合图1以及图4-图6，在一些实施例中，机座1可以包括轴承11，轴承11具有可相对转动的外圈111和内圈112，多个定子模块2的定子铁芯21连接在外圈111上，而电机还包括转子模块3，转子模块3连接在内圈112上。定子模块2通电后，产生磁场，以驱动转子模块3转动。
图7示出了图6的I部分放大示意图，结合1以及图4-图7，在一些实施方案中，外圈111的端部可以设置有第一止口1111，多个定子铁芯21依次连接在第一止口1111中。装配时，可以先将定子铁芯21的外周面贴设在第一止口1111的内壁上，以对定子铁芯21进行径向定位，再通过螺钉等连接件将定子铁芯21固定于第一止口1111的端面上，即可完成定子模块2在外圈111上的装配，此种装配方式可以保证第一环状结构和轴承11的同轴度。随后，将所有定子模块2固定完毕后，将不同的定子模块2的UVW相进行并联或者串联，最终引出整个电机的UVW相，最后，装配限位块23，并涂刷绝缘漆固化。
结合图4-图7，在一些实施方案中，内圈112的端部设置有第二止口1121，转子模块3连接在第二止口1121中。在一些实施例中，转子模块3包括转子磁轭31和多个转子磁钢32，转子磁轭31连接在第二止口1121中。多个转子磁钢32间隔设于转子磁轭31的外周面上，以形成第二环形结构。第二环形结构间隔设置于第一环形结构的内侧。多个转子磁钢32可以通过粘接等方式连接在转子磁轭31的外周面上，装配有多个转子磁钢32的转子磁轭31的外壁可以贴设在第二止口1121的内壁上，以对转子磁钢32进行径向定位，再通过螺钉等连接件在装配在第二止口1121的端部，即可完成转子子模块在内圈112上的装配，此种装配方式可以保证第二环状结构和轴承11的同轴度。
在一些实施例中，结合图5-图7，轴承11的外圈111的端部还设置有第三止口1112，第三止口1112和第一止口1111同轴设置，且第三止口1112设置于第一止口1111内，多个定子绕组22的部分设置于第三止口1112内。
在一些实施方案中，轴承11可以为接触球轴承11，例如双列角接触球轴承11，以承受定子和转子的径向力、轴向力和弯矩。
在其他实施例中，该机座1也可以包括两个轴承11，即定子模块2和转子模块3分别装配在两个轴承11上，在此不做限制。
基于上述电机，本公开还提供了一种电器设备，该电器设备包括上述电机。
本公开所提供的电器设备，由于电机的定子模块2的定子绕组22套装于对应的齿24上，多个定子绕组22串联以形成模块绕组，该定子模块2的模块绕组接线后，即可向与其配合的转子模块输出扭矩。即该定子模块可以独立制造组装，再整体装配至电机上接线即可，从而避免定子模块在装配上电机后，再将定子模块上的定子绕组装配接线等操作。由此依据本公开一些实施例的定子模块2结构简单，从而能够节约装配程序，避免出错，以降低成本，提高可靠性。
