一种定子绕组、定子和电机 技术领域
本实用新型涉及电机结构技术领域，具体地，涉及一种定子绕组、定子和电机。
背景技术
随着环境污染的日益恶化和新能源产业的蓬勃发展，电动汽车以其低排量、高效率、低成本的优势逐渐取代传统燃油车，在乘用车、商用车领域得到了广泛的推广。其中，驱动电机作为电动汽车的核心部件，常常要求其具有较高的转矩/功率密度、较宽的调速范围、较大的过载能力等，给车用驱动电机的电磁设计提出了更多更高的要求。
而现有驱动电机多采用散线作为定子绕组。以定子绕组为例说明，定子绕组采用圆线散嵌绕组槽满率较低、绕线耗量较高，常常使电机的功率密度和高效区减小。而随着绕线技术的发展，越来越多的电机厂家开始采用扁线绕组，相比于圆线而言，扁线利用率高，扁线绕组可以得到更大的电机功率密度。
然而，目前市面上的扁线电机定子多采用扁线单个成型，然后将单个成型的扁线线圈插入定子槽中，最后通过焊接的方式实现扁线绕组间的相互连接，从而形成完整的定子绕组。
现有技术中通过焊接多个线圈形成定子绕组的方式至少具有如下的弊端：
(1)增加了焊接成本，提升生产加工成本；
(2)并且焊接时由于操作工活动空间小，增加了人工强度，同时也极大地降低了生产效率；
(3)接头焊接困难，用时多，劳动强度大，易造成线圈之间连接的可靠性差，连接过程复杂，且容易产生假焊，焊接质量得不到保证；
(4)焊接完成后不容易清理机座内的焊接垃圾；
(5)焊接时定子内先要垫好防火用石棉(既繁琐又不利于操作者健康)。
实用新型内容
本实用新型解决的问题是提高制造定子绕组的生产效率，降低定子绕组的生产成本，并且保证定子绕组的质量。
为了解决上述问题，本实用新型提供一种定子绕组，所述定子绕组由一根扁平导线绕制而成，所述一根扁平导线的一部分用于缠绕形成至少两个间隔设置的线圈，所述线圈的绕制方向一致并位于所述扁平导线的同一侧。
可选地，所述定子绕组上的所述线圈为等间隔分布，并且间隔分布的所述线圈为完全相同的线圈。

具体实施方式
以下由特定的具体实施例说明本实用新型的实施方式，本领域技术人员可由本说明书所揭示的内容轻易地了解本实用新型的其他优点及功效。虽然本实用新型的描述将结合较佳实施例一起介绍，但这并不代表此实用新型的特征仅限于该实施方式。恰恰相反，结合实施方式作实用新型介绍的目的是为了覆盖基于本实用新型的权利要求而有可能延伸出 的其它选择或改造。为了提供对本实用新型的深度了解，以下描述中将包含许多具体的细节。本实用新型也可以不使用这些细节实施。此外，为了避免混乱或模糊本实用新型的重点，有些具体细节将在描述中被省略。需要说明的是，在不冲突的情况下，本实用新型中的实施例及实施例中的特征可以相互组合。
为使本实用新型的目的、技术方案和优点更加清楚，下面将结合附图对本实用新型的实施方式作进一步地详细描述。
参考图1至图5，本实用新型的第一实施方式提供一种定子绕组1，所述定子绕组1由一根扁平导线10绕制而成，所述一根扁平导线10的一部分用于缠绕形成至少两个间隔设置线圈11，所述线圈11的绕制方向一致，并且所述线圈11位于所述扁平导线10的同一侧。
线圈11可分别为第一线圈14、第二线圈15、第三线圈16、第四线圈17以及第五线圈18，并且第一线圈14、第二线圈15、第三线圈16、第四线圈17以及第五线圈18共用一根扁平导线，位于所述扁平导线的同一侧，在图2中，定子绕组上的所有线圈位于扁平导线的上侧。
本实用新型提供的定子绕组用于定子中，定子是电机静止不动的部分，其主要作用是产生旋转磁场。定子由定子铁芯以及缠绕在定子铁芯上的定子绕组组成。其中，定子铁芯为环形结构，所述定子铁芯沿着圆周方向均匀设有凸台，相邻凸台之间设有定子槽，定子槽用于容纳定子绕组，定子绕组由多个线圈组成。
参考图1至图2，本实用新型提供的一种定子绕组1由一根扁平导线10绕制而成，并且一根扁平导线10的一部分用于绕制而成至少两个间隔设置的线圈11。也就是说，不同于传统的定子绕组由多个单独的线圈连接而成，即先缠绕扁平导线形成多个单独的线圈，然后根据需要将多个单独的线圈进行连接，比如焊接连接，形成包含多个线圈的定子绕组。本实用新型提供的定子绕组1上的不同线圈11共用一根扁平导线10，在此共用一根所述扁平导线10是指所述定子绕组1为一体成型结构，即定子绕组1本就由同一根扁平导线10而成，故而组成定子绕组1的线圈与线圈之间不存在连接点，在一实施例中，该连接点为焊接点，在其他实施例中，对该连接点不作限制。
本实用新型提供的定子绕组一体成型，定子绕组上的线圈共用一根扁平导线实现了定子绕组的连续成型。相比于现有技术中需要将不同的线圈进行连接形成定子绕组的技术方案，本实用新型通过一体成型技术手段制作而成的定子绕组不存在由于线圈之间的连接不佳带来的质量问题，使得定子绕组的质量得到保证，提高了定子绕组质量的一致性；同时 也减少了定子绕组的生产工序，提高了定子绕组的生产效率，降低了人工劳动强度。
由一根扁平导线10绕制而成的多个线圈11的绕制方向一致。将该一根扁平导线的作用分为两部分，其中一部分用于绕制而成线圈，另一部分用于连接相邻的线圈。那么对该扁平导线10来说，绕制方向既包括扁平导线10形成线圈11的绕制方向，又包括连接相邻线圈11之间的扁平导线10的延伸方向。其中线圈11的绕制方向是指，以某一预设形状为标准，绕制该扁平导线使其形成与该预设形状轮廓一致的线圈的整个绕制过程。包括绕制该扁平导线10形成该线圈11过程中的绕制角度、弧度、绕制长度等参数，线圈11的绕制方向决定了该部分扁平导线绕制而成的线圈11的大小以及形状。
由一根扁平导线绕制而成的多个线圈的绕制方向一致，在一实施例中，该定子绕组上的多个线圈为大小、形状完全相同的线圈。
参考图1至图5，在本实用新型提供的其中一个实施例中，定义扁平导线10的一端为绕制起始端12，另一端为绕制终点端13，以扁平导线10的绕制起始端12开始，依次绕制而成多个间隔设置的线圈11，并且可定义在第一时间绕制而成的线圈为第一线圈14，在第二时间绕制而成的线圈为第二线圈15，在第三时间绕制而成的线圈为第三线圈16，在第四时间绕制而成的线圈为第四线圈17，在第五时间绕制而成的线圈为第五线圈18，在第N时间绕制而成的线圈为第N线圈，并且，第一线圈14、第二线圈15、第三线圈16、第四线圈17、第五线圈18与第N线圈为大小和形状完全相同的线圈，在此一、二…..N可表示时间顺序，其中，N为大于等于1的正整数。
在其他实施例中，也可以从绕制终点端13一端开始绕制，依次绕制该扁平导线10形成多个间隔分布的线圈11，直到到达该扁平导线10的绕制起始端12，绕制结束。也就是说，在本实用新型中绕制终点端13和绕制起始端12为相对概念，在不同的实施方式中可以互换，在此不作限制。
对定子绕组上的每个线圈来说，对每个线圈绕制的层数不作限制，定义每个线圈的层数为n层，n为大于等于1的正整数。当n＝1时，该线圈为单层线圈。当n≥1时，该线圈为多层线圈。参考图4以及图5，在本实用新型提供的一实施例中，n＝14，并且沿所述绕制起始端12至绕制终点端13的延伸方向，通过绕制所述扁平导线10形成5个间隔分布的线圈11，并且每个线圈11的绕制方向为逆时针(参考图2中的X方向)。在其他实施例中，沿所述扁平导线10的绕制起点端12至绕制终点端13的延伸方向，通过绕制所述扁平导线10形成5个线圈11，并且每个线圈11的绕制方向的顺时针。
需要说明的是，在其他实施例中，n＝30层，本领域技术人员可根据具体的应用选择合 适的n的数值大小，多层线圈的作用是增强磁场。并且，所述线圈的数量至少为两个，优选地，位于同一扁平导线上的所有线圈为结构形状完全相同的线圈，并且定子绕组上的线圈为间隔设置，多个线圈共用一根扁平导线。
参考图1以及图2，在一实施例中，从该扁平导线10的绕制起始端12开始，对于绕制而成线圈11的部分扁平导线10来说，按照逆时针方向(图2中X方向)绕制而成多个线圈11，在一根扁平导线10上形成多个间隔分布的按照逆时针方向绕制而成的线圈11，此时扁平导线10的绕制起始端12以及扁平导线10的绕制终点端13分别位于第一线圈14以及第五线圈18的靠近相邻线圈的一侧，即靠近第二线圈15以及第四线圈17的一侧；在另一实施例中，从该扁平导线的绕制起始端12开始，对于绕制而成线圈的部分扁平导线来说，按照顺时针方向绕制而成多个线圈，在一根扁平导线上形成多个间隔分布的按照顺时针方向绕制而成的线圈，此时扁平导线的绕制起始端以及扁平导线的绕制终点端分别位于第一线圈以及第N线圈的远离相邻线圈的一侧。
继续参考图2，沿所述绕制起始端12至绕制终点端13的延伸方向，通过绕制所述扁平导线10形成5个间隔设置的线圈，并且每个线圈的绕制方向为逆时针(图2中X方向)。在其他实施例中，沿所述扁平导线绕制起始端至绕制终点端的延伸方向，通过绕制所述扁平导线形成5个间隔设置的线圈，并且每个线圈的绕制方向的顺时针。
所述一根扁平导线10的一部分用于绕制而成多个间隔分布的第一线圈14、第二线圈15、第三线圈16、第四线圈17以及第五线圈18，所述扁平导线10的另一部分用于连接相邻线圈。参考图2，在一个实施例中，连接相邻所述线圈的所述扁平导线10为单层结构，在第一状态下，单层扁平导线10位于同一直线上。更为具体地，所述定子绕组1呈直线延伸，在一实施例中，连接相邻所述线圈的扁平导线10位于同一直线上。在此位于同一直线是指用以连接线圈之间的扁平导线10为基本完全延伸状态，即连接相邻所述线圈的扁平导线10位于同一直线上。
在另外的实施例中，连接相邻线圈的单层扁平导线不位于同一直线上，但是此时应保正将不位于同一直线上的扁平导线完全延展之后，可实现连接所述线圈的单层扁平导线位于同一直线上，并且，用于连接相邻线圈的扁平导线的长度相等。
参考图3至图5，所述一根扁平导线10的一部分用于绕制而成多个间隔分布的线圈，分别为第一线圈14、第二线圈15、第三线圈16、第四线圈17、第五线圈18。所述一根扁平导线10的另一部分用于连接相邻的线圈，连接相邻所述线圈的所述扁平导线10为单层结构，在第二状态下，所述单层扁平导线10位于同一圆周面上。更为具体地，所述定子 绕组1为圆周结构，即连接相邻所述线圈的扁平导线10位于同一圆周面上，位于定子绕组上的线圈11也位于同一圆周面上。
在具体实施中，可将呈直线型的定子绕组进行二次绕制形成呈圆周形态分布的定子绕组，相反地，也可将呈圆周面形态的定子绕组延展为呈直线型分布的定子绕组，在此不作限制。即处于第二状态下的定子绕组与处于第一状态下的定子绕组的形态可互相转换。
所述定子绕组上的所述线圈为等间隔分布，并且间隔分布的所述线圈为完全相同的线圈。在此，完全相同包括线圈的大小相同、形状相同、每个线圈绕制的层数也相同等。
所述定子绕组由一根扁平导线绕制而成，所述一根扁平导线的长度应符合至少以下两个条件：1.一根扁平导线的一部分长度可用于缠绕形成至少两个间隔设置的线圈；2.所述一根扁平导线的另一部分用于连接相邻线圈。
对于条件1：所述一根扁平导线的一部分长度可用于缠绕形成至少两个线圈。在此，对线圈的层数不作限制，在一实施例中，该线圈为单层线圈，在另一实施例中，该线圈为多层线圈。所述线圈的数量至少为两个，优选地，该两个具有多层结构的线圈为结构形状完全相同的线圈，并且定子绕组上的线圈为间隔设置，多个线圈共用一根扁平导线。
对于条件2：所述一根扁平导线的另一部分用于连接相邻线圈。在一实施例中，当所述定子绕组上的线圈的数量为2个时，所述一根扁平导线的另一部分用于连接相邻线圈，并且用于连接相邻线圈的扁平导线为单层结构。在另一实施例中，当所述定子绕组上的线圈的数量大于2时，所述不同线圈为等间隔设置，也就是说用于连接不同线圈之间的扁平导线长度相同。
参考图1至图5，一个所述定子绕组上间隔设置的线圈11的数量为5个。在其它实施例中，对定子绕组上间隔设置的线圈11的数量不作限制，只要具有上述所述的定子绕组的结构特性，皆属于本实用新型保护的范围。
需要说明的是，在本实用新型提供的一个实施例中，扁平导线是在铜等导电性良好的金属线材的外表面上设置绝缘涂层膜而成的线材，其截面为矩形形状。更为具体地所述扁平导线截面的尺寸为1mm×6mm，即扁平导线截面的厚度为1mm、宽度为6mm，扁平导线按照一定的形状依次缠绕叠加形成5个具有14层的线圈。在其他实施例中，对扁平导线的结构形状以及参数不作限制，只要利用该特性的扁平导线可形成定子绕组皆可。
参考图6至图10，本实用新型的第二实施方式中还提供了一种定子2。该定子2包括定子铁芯20，所述定子铁芯20为环形结构，所述定子铁芯20沿着圆周方向均匀设有凸台21，相邻所述凸台21之间设有卡槽23；所述卡槽23用于容纳定子绕组，所述定子绕组包 括上述第一实施方式中任一实施例中所述的定子绕组。
需要说明的是，线圈是构成定子绕组的基本单元，定子绕组就是线圈按一定规律的排列和联结。定子铁芯上定子绕组的数量也就是定子的相数，即定子铁芯上有M组定子绕组，那么这个定子就是M相定子，其中，M可以为2、3、4、5中的任一个。本实用新型对定子中定子绕组的数量不作限定，定子绕组的具体数量可以根据实际需要选择。
在一实施例中，该定子铁芯上的定子绕组数量为两个，即M＝2为两相绕组。并且该两相绕组为完全相同的定子绕组。其中该所述两个绕组上的线圈缠绕扁平导线绕制而成线圈的缠绕方向一致。换言之，沿所述扁平导线绕制起始端至绕制终点端延伸的方向，第一相绕组中的线圈缠绕所述扁平导线以形成所述线圈的绕制方向为逆时针，则与之对应的，第二相绕组中的线圈缠绕所述扁平导线以形成所述线圈的绕制方向也为逆时针。在另一实施例中，沿所述扁平导线绕制起始端至绕制终点端延伸的方向，第一相绕组中的线圈缠绕所述扁平导线以形成所述线圈的绕制方向为顺时针，则与之对应的，第二相绕组中的线圈的缠绕所述扁平导线以形成所述线圈的绕制方向也为顺时针。
并且，在两相绕组的情况下，定子绕组上的线圈依次排布于定子铁芯20上的卡槽23中，此时每相绕组的线圈各占定子铁芯20上卡槽23的一半；另外，也可以两相绕组的线圈交叉设置，在此对定子绕组之间的排布方式不作具体的限制，只要排布定子绕组之后的定子能够实现定子的具体功能皆可。
参考图8至图9，所述定子铁芯20上的定子绕组的数量为三个，即M＝3为三相绕组。定子铁芯20上线圈11的数量应为3的倍数，具体可以为3～60中任意一个能够整除3的数。本实施例的线圈11共有15个。本实施例中的绕组包括A相绕组23、B相绕组24和C相绕组25，各相绕组具有相同数量的线圈11，皆为5个，并且每个所述绕组为一体成型，即每相绕组中的线圈都是共用一根扁平导线10，更为具体地，在每相绕组中，单个线圈上以及线圈与线圈之间不存在连接点，在一实施例中，该连接点为焊接点，在其他的实施例中，该连接点可为铆接点、螺纹连接点等。具体的，A相绕组23由A相绕组23的线圈11一次排布而成，B相绕组24由B相绕组24的线圈11一次排布而成，C相绕组25由C相绕组25的线圈11依次排布而成。
在三相绕组的情况下，定子绕组的线圈之间可以采用星形接法(简称Y联接)，也可以采用三角形接法(简称Δ联接)，或者其他的连接形式，只要能够保证定子绕组可靠连接形成可靠有效的三相定子绕组即可。
参考图5，位于定子绕组一端的线圈上具有出线端，定子绕组之间通过出线端连接。 在此该出线端可为定子绕组上的绕制终点端或者绕制起始端。

对照现有技术中的将线圈安装至电机定子中的方法与本实用新型提供的将线圈安装至电机定子中的方法，可知，通过本实用新型提供的定子绕组，实现了利用一根扁平导线绕制成一个定子绕组的工艺，完全摆脱了现有技术中需将不同的单个线圈进行连接进而制成定子绕组的技术手段，极大的改善了现有工艺，大幅度提高了定子绕组的生产效率。

(3)定子绕组一体成型，所有的线圈共用一根扁平导线，线圈之间不存在连接点，使得定子绕组产品质量的一致性得到提高。
综上所述，本实用新型提供的上述实施例仅例示性说明本实用新型的原理及其功效，而非用于限制本实用新型。任何熟悉此技术的人士皆可在不违背本实用新型的精神及范畴下，对上述实施例进行修饰或改变。因此，举凡所属技术领域中具有通常知识者在未脱离本实用新型所揭示的精神与技术思想下所完成的一切等效修饰或改变，仍应由本实用新型的权利要求所涵盖。
