Description

定子组件、电机、压缩机及制冷设备
本申请要求于2019年8月26日提交中国专利局、申请号为“201910792849.X”、发明名称为“定子组件、电机、压缩机及制冷设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及压缩机技术领域，具体而言，涉及一种定子组件、一种电机、一种压缩机及一种制冷设备。
背景技术
目前，针对大排量压缩机，电机的线径粗、制造一般会比较困难，因此我们一般会采用并联的方式减小线径，不过针对更大功率的电机，线径会进一步增大，通过并联的方式也无法满足制造要求。此时我们考虑采用三角形接法，但是三角形接法采用并联连接的时候线头非常多，并且线头会比较分散，不利于配线和后续处理，也不利于产品的制造，会严重影响制造效率；如果修改成串联连接则线径太粗，又会导致槽满率不能做到太高，从而影响电机效率。
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，本申请的第一方面提供了一种定子组件。
本申请的第二方面还提供了一种电机。
本申请的第三方面还提供了一种压缩机。

本申请提供的定子组件，包括定子铁芯和设置在定子铁芯内侧壁的多个齿部，绕组绕设在齿部上以形成线圈，线圈通电后产生磁场。在绕设绕组时，绕组由第一齿开始绕制，一个绕组绕设在多个齿部上，而绕组绕设完第一齿之后，在绕设其他齿部时，均要经过第一齿两侧的槽部跨线，一方面，绕组绕制其他齿部时，均要经过第一齿两侧的槽部跨线后再绕制，使得同一个绕组的跨线集中在一个区域，也即集中在第一齿两侧的槽部内，进而可在第一齿两侧的槽部内引出抽头，使得抽头集中在一个区域，易于接线及便于将线引出后与其他部件相连接；另一方面，多个齿部上的线圈均由一根绕组绕制，避免线圈过于松散。同时，通过第一齿两侧的槽部跨线减少了在定子铁芯的端部跨线，进而降低了端部跨线的高度。

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受下面公开的具体实施例的限制。
下面参照图1至图5描述根据本申请一些实施例所述的定子组件、电机100、压缩机及制冷设备。
如图1和图2所示，根据本申请的第一方面的一个实施例，本申请提出了一种定子组件，包括：定子铁芯1、多个齿部2和绕组3。
具体地，多个齿部2设置在定子铁芯1的内侧壁且沿定子铁芯1的周向分布，相邻齿部2之间限定出槽部20，绕组3绕设在齿部2上，具体地，绕组3穿过齿部2两侧的槽部20绕设在齿部2上，使得绕组3的一部分位于齿部2两侧的槽部20内；其中，齿部2包括第一齿，绕组3由第一齿开始绕设，且绕组3绕设其他齿部2时均经过第一齿两侧的槽部20跨线。
本申请提供的定子组件，包括定子铁芯1和设置在定子铁芯1内侧壁的多个齿部2，绕组3绕设在齿部2上以形成线圈，线圈通电后产生磁场。在绕设绕组3时，绕组3由第一齿开始绕制，一个绕组3绕设在多个齿部2上，而绕组3绕设完第一齿之后，在绕设其他齿部2时，均要经过第一齿两侧的槽部20跨线，一方面，绕组3绕制其他齿部2时，均要经过第一齿两侧的槽部20跨线后再绕制，使得同一个绕组3的跨线集中在一个区域，也即集中在第一齿两侧的槽部20内，进而可在第一齿两侧的槽部20内引出抽头，使得抽头集中在一个区域，易于接线及便于将线引出后与其他部件相连接；另一方面，多个齿部2上的线圈均由一根绕组3绕制，避免线圈过于松散。同时，通过第一齿 两侧的槽部20跨线减少了在定子铁芯1的端部跨线，进而降低了端部跨线的高度。
举例而言，比如绕组3在第一齿上绕设以形成一个线圈后去绕设第二齿，此时需要经过第一齿两侧的槽部20跨线，在绕设完第二齿后需要绕设第三齿时，也要将绕组3由第二齿引向第一齿两侧的槽部20并由第一齿两侧的槽部20穿过后再绕设第三齿。
可以理解的是，绕组3绕设完一个齿部2后去绕设另一个齿部2时，由一个齿部2引至另一个齿部2的过程即为跨线，经过第一齿两侧的槽部20跨线即为绕组3由一个齿部2引至另一个齿部2时，要由第一齿两侧的槽部20穿过，即经过第一齿两侧的槽部20过线；经过定子铁芯1的端部跨线即为将绕组3由一个齿部2引至另一个齿部2时，由定子铁芯1的端部过线。
根据本申请的一个实施例，除上述实施例限定的特征之外，还进一步限定了：绕组3包括第一绕组30、第二绕组32和第三绕组34，多个齿部2组成多个齿部组，第一绕组30、第二绕组32、第三绕组34分别绕设在对应的齿部组上，任一齿部组均包括第一齿，多个齿部组中的第一齿相邻设置。
具体地，在完成绕组3的绕制后，需要将绕组3引出抽头，以与其他部件相连接，绕组3均经过第一齿两侧的槽部20跨线，使得绕组3跨线集中在了第一齿两侧的槽部20内，进而可将第一齿两侧槽部20内跨线的线切断并引出抽头，其中，在第一绕组30的起始端所在的槽部20内跨线的绕组3切断后与第一绕组30的起始端、第二绕组32的末端引出第一抽头36，在第二绕组32的起始端所在的槽部20内跨线的绕组3切断后与第二绕组32的起始端、第三绕组34的末端引出第二抽头37，在第三绕组34的起始端所在的槽部20内跨线的绕组3切断后与第三绕组34的起始端、第一绕组30的末端引出第三抽头38。
在该实施例中，如图1所示，虚线所示的位置为切断位置39，在绕组3对应的齿部组中的所有齿部2上的线圈均绕设完毕后，将以跨线的形式穿过第一绕组30对应的齿部组中的第一齿两侧的槽部20的线切断，并与第一绕组30的起始端、第二绕组32的末端引出第一抽头36，同样地，将 以跨线的形式穿过第二绕组32对应的齿部组中的第一齿两侧的槽部20的线切断，与第二绕组32的起始端、第三绕组34的末端引出第二抽头37，将以跨线的形式穿过第三绕组34对应的齿部组中的第一齿两侧的槽部20的线切断，与第三绕组34的起始端、第一绕组30的末端引出第三抽头38，将三组抽头与外部电源相连接，以供线圈通电，同时可以保证电机100接线的抽头通过绕线力进行固定，防止引出导线过于松散。
具体地，如图1所示，齿部组的数量为三个，三个齿部组对应三个绕组3设置，也即三个绕组3分别绕设在三个齿部组上。齿部2上标记为1、4、7的三个齿部2为一个齿部组，齿部2上标记为1的为该齿部组中的第一齿，齿部2上标记2、5、8的三个齿部2为一个齿部组，齿部2上标记为2的为该齿部组中的第一齿，齿部2上标记3、6、9的三个齿部2为一个齿部组，齿部2上标记为3的齿部2为该齿部组的第一齿，第一绕组30、第二绕组32和第三绕组34分别通过标记为1、2、3的三个齿部2的两端跨线，使得跨线集中在了标记为1、2、3的三个齿部2两侧的槽部20中，在三个切断位置39将以跨线形式穿过第一齿两侧槽部20的线切断，使得在标记为1和2的两个齿部2之间形成A组导线，标记为2和3的两个齿部2之间形成B组导线，标记为3和4的两个齿部2之间形成C组导线；同时，标记为8的齿部2一侧的绕组3，也即第二绕组32的末端形成另一个A组导线，标记为9的齿部2一侧的绕组3，也即第三绕组34的末端形成另一个B组导线，标记为7的齿部2一侧的绕组3，也即第一绕组30的末端形成另一个C组导线，将两个A组导线引出第一抽头36，将两个B组导线引出第二抽头37，将两个C组导线引出第三抽头38。
根据本申请的一个实施例，除上述任一实施例限定的特征之外，还进一步限定了：沿定子铁芯1的周向方向，槽部20包括位于齿部2两侧的第一槽和第二槽，齿部组还包括第二齿和第三齿，多个齿部组中的第二齿相邻设置，多个齿部组中的第三齿相邻设置。
具体地，第一绕组30、第二绕组32、第三绕组34均由对应的第一齿的第一槽开始绕设并在第一齿上形成线圈后，由第一齿的第一槽跨线并绕设在第二齿上形成线圈后，由第二齿的端部跨线后依次经过第一齿的第二槽、第一齿的 第一槽跨线后绕设在第三齿上形成线圈，其中，绕组3由第三齿的第二槽开始绕设，并由第三齿的第二槽引出。
在该实施例中，如图1所示，以第一绕组30以及第一绕组30对应的由标记为1、4、7的三个齿部2组成的齿部组为例，标记为1、4、7的三个齿部2依次为第一齿、第二齿和第三齿，将标记为1的齿部2靠近标记为2的齿部2的一侧定义为第一槽，将标记为1的齿部2靠近标记为9的齿部2的一侧定义为第二槽，第一绕组30的起始端位于第一槽内，并先绕设第一齿，在第一齿上绕设规定匝数后，由第一齿的第二槽伸出并穿过第一齿的第一槽以绕设第二齿，在第二齿上绕设完规定匝数后，经过第一齿两侧的槽部20跨线，也即第一绕组30由第二齿引至第一齿两侧的槽部20，并依次穿过第一齿的第二槽、第一齿的第一槽后由第一齿的第一槽引出至第三齿，并在第三齿上绕设规定匝数。第二绕组32和第三绕组34的绕制方式与第一绕组30相同，在此不再赘述。
进一步地，绕组3还可以包括第四齿、第五齿等，同样地，绕组3在第三齿上绕设完规定匝数后，经过端部跨线至第一齿两侧的槽部20，并经过第一齿两侧的槽部20跨线后绕设第四齿。
根据本申请的一个实施例，除上述任一实施例限定的特征之外，还进一步限定了：第一绕组30绕设在多个齿部2上，多个齿部2上的线圈的匝数相同，且第一绕组30、第二绕组32、第三绕组34各自绕设在齿部2上的线圈的匝数均相同，以使第一绕组30、第二绕组32和第三绕组34的电感量相同。
根据本申请的一个实施例，除上述任一实施例限定的特征之外，还进一步限定了：绕组3绕设在多个齿部2上，以形成多个线圈，具体地，沿定子铁芯1的周向方向，第一绕组30的多个线圈、第二绕组32的多个线圈、第三绕组34的多个线圈均匀分布，且相互间隔设置，从而使得第一绕组30、第二绕组32、第三绕组34产生的磁场更加均衡。
根据本申请的一个实施例，除上述任一实施例限定的特征之外，还进一步限定了：第一抽头36、第二抽头37和第三抽头38均位于定子铁芯1的同一端，进而可使第一抽头36、第二抽头37和第三抽头38集中在一个 区域，方便接线及后续处理。
具体地，如图2所示，电机100还包括引出线5，引出线5与第一抽头36、第二抽头37和第三抽头38相连接，以通过引出线5与其他部件相连接，具体地，如图3所示，电机100能够通过第一抽头36、第二抽头37和第三抽头38与变频器6相连接。
根据本申请的一个实施例，除上述任一实施例限定的特征之外，还进一步限定了：定子组件还包括绝缘骨架4，绝缘骨架4设置在定子铁芯1的端部，绕组3绕设完一个齿部2后引至另一个齿部2时，需要经过定子铁芯1的端部进行跨线，为避免多相绕组3接触，可通过绝缘骨架4跨线，也即在端部跨线时将线固定在绝缘骨架4上，一方面能够将各个相的绕组3分隔开，另一方面还能够使得端部的跨线更加整洁。
具体地，绝缘骨架4由绝缘材质制成。
根据本申请的一个实施例，除上述任一实施例限定的特征之外，还进一步限定了：第一绕组30、第二绕组32和第三绕组34并联设置。
具体地，第一绕组30、第二绕组32和第三绕组34呈角形连接。
根据本申请的一个具体实施例，本申请提出了一种定子组件，包括定子铁芯1和设置在定子铁芯1周向的多个齿部2，多个齿部2组成多个齿部组，第一绕组30、第二绕组32、第三绕组34分别绕设在对应的齿部组上，其中每个齿部组中均具有第一齿，且多个齿部组中的第一齿相邻设置，在绕制绕组3时，绕组3均通过第一齿两侧的槽部20跨线，使得第一绕组30、第二绕组32和第三绕组34集中在第一齿两侧跨线，进而可将第一齿两侧槽部20内的线切断后引出抽头，使得第一抽头36、第二抽头37和第三抽头38集中在同一个区域，以便于后续接线处理，同时，本申请提出的实施例不需要人工整理跨线，能够实现绕线的自动化，提高绕制的速率，缩短绕制的时间。另外，本申请中，同一个齿部组中的齿部2上的线圈均由同一个绕组3绕制，在绕制过程中并不将线切断，使得抽头能够通过绕线力进行紧固，能够防止引出线5松散。
根据本申请的第二方面，还提出了一种电机100，包括：如上述任一实施例提出的定子组件。
本申请第二方面提供的电机100，因包括上述任一实施例提出的定子组件，因此具有定子组件的全部有益效果。
根据本申请的一个实施例，除上述任一实施例限定的特征之外，还进一步限定了：电机100还包括转子组件7，与定子组件转动连接，转子组件7包括转子铁芯和永磁体，转子铁芯上设置有永磁体槽，永磁体设置在永磁体槽内。
在该实施例中，电机100还包括转子组件7，转子组件7设置在定子铁芯1内部，定子组件围设在转子组件7外部，其中，转子组件7包括转子铁芯，转子铁芯上设置有多个永磁体槽，多个永磁体槽沿转子铁芯的周向分布，永磁体设置在永磁体槽内。
具体地，定子组件与转子组件7转动连接。
具体地，如图4所示，将本申请中的定子组件应用到电机100中后，提升了电机100的制造速率，缩短了电机100的制造时间。
如图5所示，根据本申请的第三方面，还提出了一种压缩机，包括：如上述第一方面任一实施例提出的定子组件；或如上述第二方面任一实施例提出的电机100。
本申请第三方面提供的压缩机，因包括如上述第一方面任一实施例提出的定子组件；或如上述第二方面任一实施例提出的电机100，因此具有定子组件或电机100的全部有益效果。
具体地，如图5所示，压缩机还包括压缩部件8，压缩部件8包括气缸84、主轴承82、副轴承86、活塞88以及曲轴80，曲轴80一端插设在转子组件7中，另一端依次穿过主轴承82、气缸84、副轴承86，活塞88设置在气缸84内。
根据本申请的第四方面，还提出了一种制冷设备(图中未示出)，包括：如上述第一方面任一实施例提出的定子组件；或如上述第二方面任一实施例提出的电机100；或如上述第三方面任一实施例提出的压缩机。
本申请第四方面提供的制冷设备，因包括如上述第一方面任一实施例提出的定子组件；或如上述第二方面任一实施例提出的电机100；或如上述第三方面任一实施例提出的压缩机，因此具有定子组件或电机100或压缩机的全部 有益效果。
