Description

一种电机定子绕组的单根绕线结构 技术领域
本实用新型属于电机技术领域，涉及一种电机定子绕组的单根绕线结构。
背景技术
随着科技的不断发展，传统的有刷直流电机逐渐淡出市场，取而代之的是效率更高的无刷直流电机和控制系统。常规的多线无刷直流电机虽然与有刷电机相比效率已经有了很大的提升，但是也存在成品合格率低，端部不整齐等现象，产品在机器嵌线时稳定性差、铜线浪费较多。
针对以上存在的问题，人们发明了单线电机，例如中国专利文献资料公开了一种电动车及电动车用无刷单线电机及其绕组结构[申请号：201821790612.5；授权公告号：CN203734409U]，其包括定子，定子包括定子齿、线槽和绕组，其中，定子齿数量为电机工作相数的倍数，线槽数量和定子齿数量相同，绕组采用单线并绕的方式排布在定子齿上，绕组相互连接，定子上布置镶条，绕组在镶条上相互连接。
该种结构的无刷单线电机，沿定子支架的径向，相邻两个定子齿之间线槽的宽度由内向外是增大的，每个定子齿外缠绕的线圈的层数是相同的，且位于外层的线圈层的长度与位于内层的线圈层的长度是基本一致的，这就使相邻两个定子齿外缠绕的最外层的线圈层之间还具有一定的间隙，线圈不能更好的填满线槽，槽满率还有提升的空间。
发明内容
本实用新型的目的是针对现有技术中存在的上述问题，提出了一种电机定子绕组的单根绕线结构,解决的技术问题是如何合理缠绕线圈，提高槽满率。
本实用新型的目的可通过下列技术方案来实现：一种电机定子绕组的单根绕线结构,所述定子包括呈环形的定子冲片，所述定子冲片的周向等间距设有若干个定子齿，相邻两个所述定子齿之间具有定子槽，所述定子齿外通过单线的方式缠绕有若干层内线圈层，其特征在于，所述定子齿外通过单线的方式还缠绕有一层外线圈层，所述外线圈层缠绕在内线圈层外，沿定子冲片的径向，所述外线圈层并列缠绕的圈数少于内线圈层并列缠绕的圈数，相邻两个所述定子齿上的外线圈层错开设置。
外线圈层的设置，填充了相邻两个定子齿外缠绕的最外层的内线圈层之间具有的间隙，使定子齿外可以缠绕更多的铜线，提高槽满率，从而提高电机的性能。且由于沿定子冲片的径向，外线圈层并列缠绕的圈数少于内线圈层并列缠绕的圈数，相邻两个定子齿上的外线圈层错开设置，防止铜线之间的相互刮擦，有效的降低因铜线相互刮擦导致的匝间现象。
在上述的一种电机定子绕组的单根绕线结构中，以三个所述定子齿为一组，沿顺时针方向，依次记为第一定子齿、第二定子齿和第三定子齿，所述第一定子齿、第二定子齿和第三定子齿上缠绕的外线圈层依次分别记为第一外线圈层、第二外线圈层和第三外线圈层，所述第一外线圈层缠绕在第一定子齿的内端，所述第二外线圈层缠绕在第二定子齿的中间处，所述第三外线圈层缠绕在第三定子齿的外端。该种结构，合理利用相邻两个定子齿之间的间隙，布置更多铜线的同时使外线圈层可以更好的错开设置，防止铜线之间的相互刮擦，有效的降低因铜线相互刮擦导致的匝间现象。
在上述的一种电机定子绕组的单根绕线结构中，沿定子冲片的径向，所述第一外线圈层、第二外线圈层和第三外线圈层并列缠绕的圈数的总和等于或者略少于一层所述内线圈层并列缠绕的圈数。该种结构，相当于使相邻三个定子齿外缠绕的线圈多了一层，布置更多的铜线，提高槽满率，从而提高电机的性能，第一外线圈层、第二外线圈层和第三外线圈层各自并列缠绕的圈数多少可以不一致，只要错开且总的累计接近一层内线圈层的圈数即可。
作为另一种情况，在上述的一种电机定子绕组的单根绕线结构中，以两个所述定子齿为一组，沿顺时针方向，依次记为第四定子齿和第五定子齿，所述第四定子齿和 第五定子齿上缠绕的外线圈层依次分别记为第四外线圈层和第五外线圈层，所述第四外线圈层缠绕在第四定子齿的中间处，所述第五外线圈层缠绕在第五定子齿的外端。该种布置方式，适合槽底的宽度过小的情况，铜线可以不嵌入槽底，只缠绕在定子齿的中间处和外端；该种结构，合理利用相邻两个定子齿之间的间隙，布置更多铜线的同时使外线圈层可以更好的错开设置，防止铜线之间的相互刮擦，有效的降低因铜线相互刮擦导致的匝间现象。
在上述的一种电机定子绕组的单根绕线结构中，沿定子冲片的径向，所述第四外线圈层和第五外线圈层并列缠绕的圈数的总和少于一层所述内线圈层并列缠绕的圈数。该种结构，尽可能的布置更多的铜线，提高槽满率，从而提高电机的性能。
作为第三种情况，在上述的一种电机定子绕组的单根绕线结构中，以两个所述定子齿为一组，沿顺时针方向，依次记为第六定子齿和第七定子齿，所述第六定子齿和第七定子齿上缠绕的外线圈层依次分别记为第六外线圈层和第七外线圈层，所述第六外线圈层缠绕在第六定子齿的内部，所述第七外线圈层缠绕在第七定子齿的外部。该种结构，合理利用相邻两个定子齿之间的间隙，布置更多铜线的同时使外线圈层可以更好的错开设置，防止铜线之间的相互刮擦，有效的降低因铜线相互刮擦导致的匝间现象。
在上述的一种电机定子绕组的单根绕线结构中，沿定子冲片的径向，所述第六外线圈层和第七外线圈层并列缠绕的圈数的总和等于或者略少于一层所述内线圈层并列缠绕的圈数。该种结构，相当于使相邻两个定子齿外缠绕的线圈多了一层，布置更多的铜线，提高槽满率，从而提高电机的性能。
在上述的一种电机定子绕组的单根绕线结构中，所述内线圈层的层数为1-4层。内线圈层的层数根据槽的宽度合理布置。
与现有技术相比，本实用新型提供的一种电机定子绕组的单根绕线结构具有以下优点：
1、本绕线结构设置外线圈层，来填充相邻两个定子齿之间的间隙，使定子齿外可以缠绕更多的铜线，布置更多的铜线，提高槽满率，从而提高电机的性能。
2、本绕线结构设置的外线圈层是错开设置的，合理利用空间，防止铜线之间的相互刮擦，有效的降低因铜线相互刮擦导致的匝间现象。

如图2所示，本实施例同实施例一的结构和原理基本相同，不同的地方在于，本实施例中，以两个定子齿1为一组，沿顺时针方向，依次记为第四定子齿14和第五定子齿15，第四定子齿14和第五定子齿15缠绕的外线圈层4依次分别记为第四外线圈层44和第五外线圈层45，第四外线圈层44缠绕在第四定子齿14的中间处，第五外线圈层45缠绕在第五定子齿15的外端，沿定子冲片的径向，第四外线圈层44和第五外线圈层45并列缠绕的圈数的总和少于一层内线圈层3并列缠绕的圈数，且多于一层内线圈层3并列缠绕的圈数的一半。第四外线圈层44和第五外线圈层45并列缠绕的圈数均为一层内线圈层3并列缠绕的圈数的1/3，在实际生产中，第四外线圈层44和第五外线圈层45并列缠绕的圈数可以分别为一层内线圈层3并列缠绕的圈数的1/3和1/2，也可分别为1/4和1/2。
实施例三

本文中所描述的具体实施例仅仅是对本实用新型精神作举例说明。本实用新型所属技术领域的技术人员可以对所描述的具体实施例做各种各样的修改或补充或采用类似的方式替代，但并不会偏离本实用新型的精神或者超越所附权利要求书所定义的范围。
尽管本文较多地使用了定子齿1、第一定子齿11、第二定子齿12、第三定子齿13、第四定子齿14、第五定子齿15、第六定子齿16、第七定子齿17、定子槽2、内线圈层3、外线圈层4、第一外线圈层41、第二外线圈层42、第三外线圈层43、第四外线圈层44、第五外线圈层45、第六外线圈层46、第七外线圈层47等术语，但并不排除使用其它术语的可能性。使用这些术语仅仅是为了更方便地描述和解释本实用新型的本质；把它们解释成任何一种附加的限制都是与本实用新型精神相违背的。
