技术领域
本申请涉及电机技术领域，具体而言，涉及一种定子铁芯、定子组件、电机和机电设备。
背景技术
现有的电机，其定子铁芯的结构通常为：在完整的环形定子轭部上设置定子齿部，定子齿部包括多个定子齿身和与多个定子齿身一一对应的定子齿靴，整个定子铁芯重量较大，不利于电机的轻量化，且成本较高。
发明内容
本申请旨在至少解决现有技术或相关技术中存在的技术问题之一。
为此，本申请的一个方面在于提出了一种定子铁芯。
本申请的另一个方面在于提出了一种定子组件。
本申请的再一个方面在于提出了一种电机。
本申请的又一个方面在于提出了一种机电设备。
有鉴于此，根据本申请的一个方面，提出了一种定子铁芯，包括：定子轭部，该定子轭部具有缺口，该定子轭部包括至少一个定子轭段；定子齿部，该定子齿部包括至少一个定子齿靴和至少两个定子齿身，该至少两个定子齿身沿该定子铁芯的周向排布，任一该定子齿身的两端分别与该定子轭段及该定子齿靴相连；其中，任意相邻的两个该定子齿身通过该定子齿靴或该定子轭段相连，且该定子齿部的定子齿靴与该定子轭部的定子轭段沿该定子铁芯的周向交错排布。
本申请第一个方面的实施例提供的定子铁芯，利用沿定子铁芯的周向交错排布的定子齿靴和定子轭段将多个定子齿身连接在一起，使得定子轭部、定子齿部连接成为整体。换言之，任意相邻的两个定子齿身仅通过定子齿靴或定子轭段连接为一个整体，则对于通过定子齿靴相连且相邻的任意两个定子齿身，这两个定子齿身朝向定子轭部的一端没有通过定子轭段相连，故而定子轭部在这两个定子齿身之间是断开的并且具有缺口。因此，本申请中的定子轭部为非环形结构，相较于现有技术中的环形定子轭部，减小了定子轭部的周向尺寸，从而降低了定子铁芯的重量，也有利于减少与定子铁芯相连的绝缘件的尺寸，有利于电机的轻量化，同时也降低了产品的生产成本。此外，定子轭部的缺口部位，便于气流通过，有利于电机内部散热，从而有利于提高电机的使用可靠性。
根据本申请的第二个方面，提供了一种定子组件，包括：如第一个方面实施例中任一项的定子铁芯；绕组线圈，绕设在该定子铁芯上；绝缘件，与该定子铁芯相连，位于该绕组线圈与该定子铁芯之间，用于隔离该绕组线圈与该定子铁芯。
根据本申请的第三个方面，提供了一种电机，包括：如第二个方面实施例的定子组件；和转子组件，与该定子组件同心布置。
根据本申请的第四个方面，提供了一种机电设备，包括：设备主体；和如第三个方面实施例的电机，设在该设备主体中。
本申请的附加方面和优点将在下面的描述部分中变得明显，或通过本申请的实践了解到。

具体实施方式
为了能够更清楚地理解本申请的上述目的、特征和优点，下面结合附图和具体实施方式对本申请进行进一步的详细描述。需要说明的是，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本申请，但是，本申请还可以采用其他不同于在此描述的其他方式来实施，因此，本申请的保护范围并不限于下面公开的具体实施例的限制。
本申请第一个方面的实施例提供的定子铁芯20，包括：定子轭部111和定子齿部112。
具体地，定子轭部111包括至少一个非环形的定子轭段1115，如图2、图4、图6所示。
定子齿部112包括至少一个定子齿靴1122和至少两个定子齿身1121，如图1、图3、图5、图7、图9和图11所示。至少两个定子齿身1121沿定子铁芯20的周向排布，任一定子齿身1121的两端分别与定子轭段1115及定子齿靴1122相连。
其中，任意相邻的两个定子齿身1121通过定子齿靴1122与定子轭段1115中的一者相连，如图1、图3、图5、图7、图9和图11所示，且定子齿部112的定子齿靴1122与定子轭部111的定子轭段1115沿定子铁芯20的周向交错排布。
本申请第一个方面的实施例提供的定子铁芯20，利用沿定子铁芯20的周向交错排布的定子齿靴1122和定子轭段1115将多个定子齿身1121连接在一起，使得定子轭部111、定子齿部112连接成为整体。
换言之，任意相邻的两个定子齿身1121仅通过定子齿靴1122或定子轭段1115连接为一个整体，则对于通过定子齿靴1122相连且相邻的任意两个定子齿身1121，这两个定子齿身1121朝向定子轭部111的一端没有通过定子轭段1115相连，故而定子轭部111在这两个定子齿身1121之间是断开的并且具有缺口。
因此，本申请中的定子轭部111为非环形结构，相较于现有技术中的环形定子轭部111，减小了定子轭部111的周向尺寸，从而降低了定子铁芯20的重量，也有利于减少与定子铁芯20相连的绝缘件12的尺寸，有利于电机1的轻量化，同时也降低了产品的生产成本。
此外，定子轭部111的缺口部位，便于气流通过，有利于电机1内部散热，从而有利于提高电机1的使用可靠性。
下面结合附图介绍一些实施例。
实施例一
定子铁芯20为一体式结构，如图1所示。定子铁芯20由多个冲片叠压形成。
定子铁芯20为一体式结构，直接由多个冲片叠压形成，则只需根据定子铁芯20的形状选择适配的冲片即可，然后利用焊接或者胶粘等方式将多个冲片叠压并保持在一起，即可得到定子铁芯20，工艺简单，易于成型。
进一步地，定子铁芯20为焊接成型的一体式结构。定子轭段1115的侧壁设有至少一个凸出部或凹陷部，定子铁芯20的焊接位1111设在凸出部或凹陷部处，如图1所示。
在定子轭段1115的侧壁设至少一个凸出部或凹陷部，将焊接位1111设在该凸出部处(如图1所示)或凹陷部处，则焊接时直接沿着该凸出部或者凹陷部进行焊接，即可将多个冲片焊接在一起，得到的焊缝较直，较为美观，也能够尽可能降低焊缝对磁路的影响。
实施例二
定子铁芯20包括至少两个拼接部11，如图2至图11所示。至少两个拼接部11相互拼接形成定子铁芯20。各拼接部11分别由多个冲片叠压形成。
将定子铁芯20拆分为至少两个拼接部11，各个拼接部11分别由多个冲片叠压形成，则单个拼接部11的冲片尺寸较小，有利于减少加工冲片产生的废料量，从而提高原材料的利用率，进而降低生产成本。
同时，本方案也便于根据需要选择先绕线再拼接或者先拼接再绕线，有利于简化绕线工艺，提高装配效率。
进一步地，对于单个拼接部11，也可以设置凸出部或凹陷部，将焊接位1111设在凸出部或凹陷部处，如图2、图4、图6、图8和图10所示，通过焊接将多个冲片保持在一起，形成拼接部11。
具体地，记至少两个拼接部11的拼接位置为定子铁芯20的拼接处。其中，定子齿身1121与定子轭段1115被构造成分体式结构，如图4至图7所示。拼接处包括定子齿身1121与定子轭段1115的交接处。
定子铁芯20的拼接处也是定子铁芯20的分割处，即：沿着拼接处将定子铁芯20断开，使定子铁芯20形成至少两个拼接部11。换言之，定子铁芯20被沿着定子齿身1121与定子轭段1115的交接处、定子轭段1115、定子齿靴1122中的至少一部分分割断开，形成分体式结构。
将定子齿身1121与定子轭段1115构造成分体式结构，单独成型，然后拼接在一起，则定子齿身1121与定子轭段1115的交接处形成拼接处的至少一部分。该方案对于轭部绕线的产品(如图17和图18所示)而言，便于根据需要选择先轭部绕线，再将完成绕线作业的定子轭段1115与定子齿身1121拼接在一起，有利于简化绕线工艺，提高装配效率。
同时，单个定子轭段1115的结构相对规整，单个定子轭段1115的冲片加工成型时产生的废料也较少，有利于进一步降低原材料的废料量，进一步提高原材料的利用率。
实施例三
与实施例二的区别在于：定子轭段1115被构造成至少两个沿定子铁芯20的周向相互拼接的轭部段1116，如图8至图11所示。拼接处包括至少两个轭部段1116的交接处。
将定子轭段1115构造成至少两个轭部段1116，多个轭部段1116沿定子铁芯20的周向相互拼接，便于根据需要将两个轭部段1116、两个定子齿身1121及定子齿靴1122设计成一个整体，则装配时只需将相邻的轭部段1116沿周向组装即可，有利于减少拼接部11的数量，减少拼接位置，从而提高装配效率。
实施例四
与实施例二的区别在于：定子齿靴1122被构造成至少两个沿定子铁芯20的周向相互拼接的齿靴段，如图2和图3所示。拼接处包括至少两个齿靴段的交接处。
将定子齿靴1122构造成至少两个齿靴段，多个齿靴段沿定子铁芯20的周向相互拼接，便于根据需要将两个齿靴段、两个定子齿身1121及定子轭段1115设计成一个整体，则装配时只需将相邻的齿靴段沿周向组装即可，有利于减少拼接部11的数量，减少拼接位置，从而提高装配效率。
在上述实施例二至实施例四中，进一步地，相邻的两个拼接部11中的一个设有凸部1113，另一个设有与凸部1113相适配的凹部1114，如图2至图11所示，凸部1113与凹部1114凹凸配合以使相邻的两个拼接部11拼接相连。
相邻的两个拼接部11通过凸部1113与凹部1114的配合实现组装，装配较为便捷，有利于进一步提高装配效率。
具体地，凸部1113的形状可以为但不局限于：半圆形(如图4至图11所示)、三角形、燕尾形(如图2和图3所示)等。
进一步地，拼接部11的周向两端设有拼接凸台1112，如图8至图11所示，拼接凸台1112沿定子铁芯20的径向凸出于拼接部11，拼接凸台1112设有凸部1113或凹部1114。
在拼接部11的周向两端设置拼接凸台1112，并将凸部1113或者凹部1114设在拼接凸台1112上，则装配时将相邻的拼接部11的拼接凸台1112对准，使凸部1113一一嵌入凹部1114，即可实现多个拼接部11的周向组装，装配方便快捷。
同时，由于拼接凸台1112沿定子铁芯20的径向凸出于拼接部11，不会对拼接部11的周向结构造成影响，有利于保证拼接部11周向结构的完整性，进而降低对磁路的影响。
比如：对于前述将定子轭段1115构造成至少两个轭部段1116的方案，可以将两个轭部段1116、两个定子齿身1121及定子齿靴1122设计成一个整体，如图8和图10所示，在两个轭部段1116相背离的端部分别设置拼接凸台1112，多个拼接部11直接通过拼接凸台1112对接即可，简单快捷。
在本申请的一些实施例中，进一步地，定子齿靴1122沿定子铁芯20的周向凸出于相连的定子齿身1121。
定子齿靴1122沿定子铁芯20的周向凸出于相连的定子齿身1121，便于连接相邻的定子齿身1121，也有利于增加定子齿靴1122的面积，进而提高定子铁芯20与转子组件14的配合效果。

定子齿靴1122沿定子铁芯20的周向延伸，既便于连接相邻的两个定子齿身1121，也有利于减小产品的轴向尺寸。
定子轭段1115位于定子齿靴1122的径向外侧，能够与转子组件14配合形成内转子电机1。由于内转子电机1的定子轭部111半径较大，因而采用本申请的方案有利于显著减小定子轭部111的周向尺寸，进而显著降低电机1重量和成本。当然，定子轭段1115也可以位于定子齿靴1122的径向内侧，与转子组件14配合形成外转子电机1。
在本申请的一些实施例中，定子轭段1115的数量为至少两个，定子齿靴1122的数量与定子轭段1115的数量相等，定子轭段1115及定子齿靴1122沿定子铁芯20的周向一一交错排布，如图1、图3、图5、图7、图9和图11所示。
多个定子轭段1115与多个定子齿靴1122沿定子铁芯20的周向一一交错排布，形成规则的结构，相较于现有技术中的环形轭部，定子轭部111减少一半，有利于显著降低电机1重量和成本。
在本申请的一些实施例中，定子轭段1115呈弧线形，如图4、图6、图8和图10所示。

定子齿靴1122呈弧线形或直线形，结构规整，便于加工成型。并且，这样设置使得定子轭段1115与定子齿靴1122的作用可以互换，因而使得该定子铁芯20既能够用于内转子电机(内侧为定子齿靴1122，外侧为定子轭部111，如图12、图14、图16、图18、图20所示)，也可以用于外转子电机(内侧为定子轭部111，外侧为定子齿靴1122)，扩大了定子铁芯20的使用范围。

本申请第二个方面的实施例提供的定子组件10，因包括第一个方面实施例中任一项的定子铁芯20，因而具有上述任一实施例所具有的一切有益效果，在此不再赘述。
具体地，绕组线圈13绕设在定子齿身1121上，如图12、图14、图16和图20所示，便于根据需要选择绕线的位置及数量。或者，绕组线圈13绕设在定子轭部111上，形成环形绕组，如图18所示，则相邻的两个定子齿身1121之间形成供气流经过的风道，有利于电机1散热，进而提高电机1内芯片等电气元件的使用可靠性。
其中，绝缘件12通常为框架结构，即绝缘框架，可以通过注塑成型的方式与定子铁芯20相连；绝缘框架也可以单独加工，扣在定子铁芯20上，或者与定子铁芯20插装配合。
在本申请的一些实施例中，绝缘件12与定子铁芯20相连形成一体式结构，如图12所示，以使绕组线圈13适于在绝缘件12与定子铁芯20形成一体式结构之后绕设在定子铁芯20上。
绝缘件12与定子铁芯20相连形成一体式结构，不可分离，生产过程中需先将绝缘件12与定子铁芯20连接为一体，具体可以通过注塑成型的方式将绝缘件12注塑在定子铁芯20上，然后进行绕线作业。该方案能够有效保证绝缘件12与定子铁芯20的连接可靠性，进而提高电机1的使用可靠性。
在本申请的另一些实施例中，绝缘件12与定子铁芯20为分体式结构，且绝缘件12为分体式结构，绝缘件12包括至少两个绝缘部，至少两个绝缘部与定子铁芯20的多个拼接部11一一对应，以使：绕组线圈13适于通过绕线工装绕设在绝缘部上，如图17和图18所示，且绝缘部在完成绕线作业之后与对应的拼接部11相连。

在上述两个实施例中，绝缘件12与定子铁芯20为分体式结构，分开成型，然后组装。并且，绝缘件12也为分体式结构，拆分为至少两个绝缘部，与定子铁芯20的多个拼接部11一一对应。这样，生产过程中，可以根据需要先绕线再对定子铁芯20进行拼接组装，有利于降低绕线难度，从而提高装配效率。
相较于直接在定子铁芯20上绕线，然后连接定子铁芯20与绝缘件12的方案，本方案能够防止直接在定子铁芯20上绕线作业时定子铁芯20受力过大而发生弯曲变形，有利于提高定子铁芯20形状的稳定性。
具体地，可以先将绝缘部套在绕线工装上，沿预设方向绕制绕组线圈13，如图17所示，待绕线完成后，将绝缘部安装在拼接部11上，然后将多个拼接部11拼接在一起即可，如图18所示。
或者，也可以先将绝缘部安装在拼接部11上，形成一个组件，然后沿预设方向在绝缘部与拼接部11形成的组件上绕设绕组线圈13，待绕线完成后，如图15所示，再将多个拼接部11拼接在一起即可，如图16所示。
