本实用新型涉及扁线电机技术领域，特别的涉及一种并排相绕组、定子及电机。
背景技术
电机(包括电动机和发电机)是根据电磁感应原理将电能转换为机械能(或将机械能转换为电能)的一种装置，可作为各种电器如家用电器、各种机械如电动车、电动汽车的动力来源或发电装置。电机根据其工作电源的种类可分为直流电机和交流电机，而交流电机又可分为单相电机和多相电机(如三相电机等)。电机包括定子和转子，在定子的定子铁芯槽内设置有绕组。传统的绕组采用圆形导线绕制而成，虽然绕制工艺相对简单，但铁芯槽内空间利用率低，端部无用铜浪费大，且功率密度低，逐渐被扁铜线或矩形截面铜线替代。
目前，扁铜线或矩形截面铜线的绕组主要采用整体成U形弯折的分段式的发卡导体连接而成，在采用短距绕组时，同一定子铁芯槽内存在两相或多相绕组的发卡导体支腿部，由于不同相绕组之间的电压不同，在电机运行时，同一槽内相邻的不同相绕组的支腿部之间会有电压差，容易对发卡导体所使用的扁铜线材料的绝缘漆皮造成损伤，从而影响电机的使用寿命，而相绕组中发卡导体的设置方式影响槽内的不同相绕组支腿部的布置位置，现有技术中，为了将这种电压差的影响降到最低，往往采用种类繁多的发卡导体结构来实现相绕组的绕线结构，该结构的发卡导体形状多，生产成本高，并且装配困难，不利于生产制造。
发明内容
针对上述现有技术的不足，本发明所要解决的技术问题是：如何提供一种发卡导体种类少，结构布置合理，能够减少同槽内相间导体的邻接面积，有利于降低相间放电发生的概率，提高电机使用寿命且有利于生产制造的并排相绕组、定子及电机。
为了解决上述技术问题，本发明采用了如下的技术方案：
一种并排相绕组，其特征在于，包括两组由Q个线圈环组成的线圈环组，每个所述线圈环由P个沿定子周向均布设置的发卡导体组串联而成，P为磁极对数，Q为每极每相槽数，且为大于1的整数；所述发卡导体组包括至少两个在定子周向错位布置的发卡导体，所述发卡导体包括整体呈U型弯折的发卡主体，所述发卡主体包括两个相互平行设置的支腿部和连接在两个支腿部一端的头部，两个所述支腿部的另一端各设置有一个支脚，所述发卡导体组上在定子周向错位布置的发卡导体上相邻近的支腿部位于相邻的两个槽位内；
每组所述线圈环组中的Q个线圈环设置于定子周向连续相邻的Q个槽位内；在顺时针方向上，其中一组线圈环组中位于第A个槽位的线圈环上的发卡导体组与另一组线圈环组中位于第A个槽位的线圈环 上的发卡导体组在定子周向上错位布置，使两个线圈环上相互错位布置的两个发卡导体组中相邻近的发卡导体在定子径向上相互紧邻地并排设置。
为了保证定子铁芯槽内均匀满布发卡导体的支腿部，每个发卡导体组上的各支腿部在定子铁芯槽内的相对位置均一致，而由于在顺时针方向上位于各自线圈环组上对应位置的线圈环上的发卡导体组错位布置，使错位布置的两个发卡导体组中相邻近的发卡导体在定子径向上相互紧邻地并排设置，这样，两个线圈环上的发卡导体组的支腿部在同一个槽位内相互填充，最终使得每个槽位内属于同一相的支腿部沿该槽位的一侧依次相互紧邻地设置，即使同一槽位内布置有分属于不同两相的支腿部，二者也只有一侧相互邻近，大大减小了同槽内相间导体的邻接面积，有利于降低相间放电发生的概率，提高电机使用寿命。而且由于每个发卡导体组上发卡导体的种类都一样，只要发卡导体组上发卡导体种类确定，就能够确定整个相绕组上的发卡导体种类，避免其他种类的发卡导体的使用，从而使发卡导体的种类更少，并且由于不同种类的发卡导体的头部在定子径向上相互紧邻地并排设置，因此多种发卡导体都可通过同一套模具来成型，从而提高生产效率和成本。
进一步，装配状态下，每个定子铁芯槽内具有2N个支腿部，N为2或大于2的奇数。
作为优化，装配状态下，每个定子铁芯槽内具有4个支腿部，所述发卡导体组包括2个发卡导体，其中一个发卡导体为两个支脚沿发卡主体的宽度方向上沿相背离方向偏转弯折的波形导体，另一个为整体呈环形的O形导体，所述O形导体的两个所述支脚在发卡主体的宽度方向上朝向中部偏转弯折，并在发卡主体的厚度方向上错位间隔设置；所述波形导体与所述O形导体上相邻近的两个支腿部位于相邻的槽内，且二者的另一个支腿部位于相背离的方向上。
作为优化，装配状态下，每个定子铁芯槽内具有6个支腿部，所述发卡导体组包括3个发卡导体，其中一个发卡导体为两个支脚沿发卡主体的宽度方向上沿相背离方向偏转弯折的波形导体，另两个为整体呈环形的O形导体，所述O形导体的两个所述支脚在发卡主体的宽度方向上朝向中部偏转弯折，并在发卡主体的厚度方向上错位间隔设置；两个所述O形导体在定子径向上相互间隔地并排设置；所述波形导体与所述O形导体上相邻近的两个支腿部位于相邻的槽内，且二者的另一个支腿部位于相背离的方向上。

作为优化，装配状态下，每个定子铁芯槽内具有10个支腿部，所述发卡导体组包括两个在定子径向上相互间隔地并排设置的第一类偏U形导体和两个在定子径向上相互间隔地并排设置的第二类偏U形导体，以及一个与所述第一类偏U形导体或第二类偏U形导体在定子径向上相互间隔地并排设置的波形导体；所述第一类偏U形导体和第二类偏U形导体上相邻的两个支腿部位于相邻的槽内，且所述第一类偏U形导体的两个支脚在发卡主体的宽度方向上朝向所述第二类偏U形导体偏转弯折，所述第二类偏U形导体的两个支脚在发卡主体的宽度方向上朝向所述第一类偏U形导体偏转弯折。

具体实施方式
下面结合实施例对本发明作进一步的详细说明。
实施例1：如图1～图15所示，一种电机，包括定子，所述定子包括定子铁芯8和三相安装在所述定子铁芯8上的相绕组，相绕组上各支路的一端通过星点连接导体7相互连接，且每个相绕组上的两个并联支路的另一端通过电源引出导体6并联连接设置。
所述定子铁芯8包括整体呈圆筒形的主体，在所述定子铁芯8的内圈沿周向设置有多个沿径向朝内开口的定子铁芯槽，所述定子铁芯槽的下端为插入侧(或称冠侧)，上端为连接侧。
本实施例中，每极每相槽数Q＝2，极对数P＝4，且装配状态下，每个定子铁芯槽内具有4个支腿部，即每个相绕组包括两组均由2个线圈环组成的线圈环组，分别为a和b；其中，线圈环组a包括在顺时针方向上依次设置的线圈环a1和线圈环a2，且线圈环a1和线圈环a2位于定子周向连续相邻的两个槽 位内。线圈环组b包括在顺时针方向上依次设置的线圈环b1和线圈环b2，且线圈环b1和线圈环b2也位于定子周向连续相邻的两个槽位内。
线圈环a1、a2、b1和b2均由4个沿定子周向均布设置的发卡导体组串联而成，如图4和图5所示。
其中，发卡导体组包括两个在定子周向错位布置的发卡导体，其中一个发卡导体为波形导体，另一个发卡导体为整体呈环形的O形导体；所述波形导体和O形导体均包括整体呈U型弯折的发卡主体，所述发卡主体包括两个相互平行设置的支腿部和连接在两个支腿部一端的头部，两个所述支腿部的另一端各设置有一个支脚。所述波形导体的两个支脚沿发卡主体的宽度方向上沿相背离方向偏转弯折设置，如图6所示；所述O形导体的两个所述支脚在发卡主体的宽度方向上朝向中部偏转弯折，并在发卡主体的厚度方向上错位间隔设置，如图7所示；所述波形导体与所述O形导体上相邻近的两个支腿部位于相邻的槽内，且二者的另一个支腿部位于相背离的方向上，如图8所示。
本实施例中，线圈环组a内的线圈环a1和线圈环a2相互串联形成一个支路，如图9所示；线圈环组b内的线圈环b1和线圈环b2相互串联形成另一个支路，如图10所示；形成2个并联设置的支路，如图11和图12所示，其中，图11中用实线表示的为图9中线圈环a1和线圈环a2串联而成的支路，用虚线表示的为图10中线圈环b1和线圈环b2串联而成的支路，图9、图10和图11的视角完全一致，从图9和图10中与图11的圆圈处相对应的位置可以看出，线圈环a1和a2在圆圈处的发卡导体为波形导体，线圈环b1和b2在圆圈处的发卡导体为O形导体。图12为图11中圆圈处的放大结构示意图，从图12中可以看出，线圈环b1的O形导体与线圈环a1的波形导体在径向方向上相互紧邻地并排设置；线圈环b2的O形导体和线圈环a2的波形导体在径向方向上相互紧邻地并排设置。
另外，如图13和图14所示，在本实施例中，同一个发卡导体组上，波形导体和O形导体位于相邻槽位的两个支腿部分别位于各自槽位内的第二和第三层，所述波形导体和O形导体的另外两个支腿部分别位于各自所在槽位内的第一层和第四层。为便于说明，如图15所示，以线圈环组a为例，在线圈环组a内，位于线圈环a1上的发卡导体组上相互邻近两个支腿部分别位于相邻的第k+1槽和第k+2槽上的第二层和第三层，而与之相邻的位于线圈环a2上的发卡导体组上相互邻近两个支腿部分别位于相邻的第k+2槽和第k+3槽上的第二层和第三层，而k+1槽和第k+2槽内的第一层分别由位于该发卡导体组逆时针方向一侧的线圈环b1和b2上并排设置的发卡导体的支腿部进行填充，而第k+2槽和第k+3槽上的第四层则分别由位于该发卡导体组顺时针方向一侧的线圈环b1和b2上的与之并排设置的发卡导体的支腿部进行填充。这样，使得该相绕组中，在每极中，位于中部的(即k+2槽)槽位内完全填充有属于同一相的发卡导体的支腿部，且位于该槽两侧的槽位(即k+1槽和k+3槽)内，只有靠近定子内层或外层的一半槽内填充有属于该相的发卡导体的支腿部，另一半填充有属于相邻的另一相绕组的发卡导体的支腿部，如图15所示。使得相邻两个相绕组在同一个定子铁芯槽内只有一个面相互贴近，减少同槽内不同相之间的导体邻接面积，有利于降低相间放电发生的概率，提高电机使用寿命。而且从图1中可以看到， 采用本发明方案进行布置，能够使发卡导体的排布更加有序，结构布置更加合理。
实施例2：
如图16～图27所示，本实施例与实施例1一样，每极每相槽数Q＝2，极对数P＝4，即每个相绕组包括两组均由2个线圈环组成的线圈环组，分别为a和b；其中，线圈环组a包括在顺时针方向上依次设置的线圈环a1和线圈环a2，且线圈环a1和线圈环a2位于定子周向连续相邻的两个槽位内。线圈环组b包括在顺时针方向上依次设置的线圈环b1和线圈环b2，且线圈环b1和线圈环b2也位于定子周向连续相邻的两个槽位内。
与实施例1的主要区别在于：装配状态下，每个定子铁芯槽内具有6个支腿部。
本实施例中，发卡导体组包括3个发卡导体，其中一个发卡导体为波形导体，另两个发卡导体为整体呈环形的O形导体；所述波形导体和O形导体均包括整体呈U型弯折的发卡主体，所述发卡主体包括两个相互平行设置的支腿部和连接在两个支腿部一端的头部，两个所述支腿部的另一端各设置有一个支脚。所述波形导体的两个支脚沿发卡主体的宽度方向上沿相背离方向偏转弯折设置，如图6所示；所述O形导体的两个所述支脚在发卡主体的宽度方向上朝向中部偏转弯折，并在发卡主体的厚度方向上错位间隔设置，如图7所示；两个所述O形导体在定子径向上相互间隔地并排设置，所述波形导体与所述O形导体上相邻近的两个支腿部位于相邻的槽内，且二者的另一个支腿部位于相背离的方向上，如图21所示。
如图19、20和22所示，线圈环组a内的线圈环a1和线圈环a2相互串联形成一个支路；如图23所示，线圈环组b内的线圈环b1和线圈环b2相互串联形成另一个支路，形成2个并联设置的支路，如图24所示。
另外，如图25和图26所示，在本实施例中，同一个发卡导体组上，波形导体和两个并排设置的O形导体位于相邻槽位的三个支腿部分别位于相邻两个槽位内的第二和第四层、第六层，所述波形导体和O形导体的另外3个支腿部分别位于各自所在槽位内的第五层和第三层、第一层。为便于说明，如图15所示，以线圈环组a为例，在线圈环组a内，位于线圈环a1上的发卡导体组上相互邻近的支腿部分别位于相邻的第k+1槽内的第二层和第k+2槽内的第四层、第六层，而与之相邻的位于线圈环a2上的发卡导体组上相互邻近的支腿部分别位于相邻的第k+2槽内的第二层和第k+3槽内的第四层、第六层，而k+1槽和第k+2槽内的第一层和第三层分别由位于该发卡导体组逆时针方向一侧的线圈环b1和b2上并排设置的O形导体的支腿部进行填充，而第k+2槽和第k+3槽上的第六层则分别由位于该发卡导体组顺时针方向一侧的线圈环b1和b2上的波形导体的支腿部进行填充。这样，使得该相绕组中，在每极中，位于中部的(即k+2槽)槽位内完全填充有属于同一相的发卡导体的支腿部，且位于该槽两侧的槽位(即k+1槽和k+3槽)内，只有靠近定子内层或外层的一半槽内填充有属于该相的发卡导体的支腿部，另一半填充有属于相邻的另一相绕组的发卡导体的支腿部，如图27所示。使得相邻两个相绕组在同一个定子铁芯 槽内只有一个面相互贴近，减少同槽内不同相之间的导体邻接面积，有利于降低相间放电发生的概率，提高电机使用寿命。而且从图1中可以看到，采用本发明方案进行布置，能够使发卡导体的排布更加有序，结构布置更加合理。
实施例3：
与实施例2一样，装配状态下，每个定子铁芯槽内具有6个支腿部。
与实施例2的主要区别在于，如图28所示，所述发卡导体组包括3个发卡导体，其中一个发卡导体为整体呈环形的O形导体，另外两个导体为在定子径向上相互间隔地并排设置的第一类偏U形导体和第二类偏U形导体，如图31和32所示，所述第一类偏U形导体上的一个支腿部上的支脚与第二类偏U形导体上的另一个支腿部上的支脚在发卡主体的宽度方向上沿相背离的方向偏转弯折，且二者的另外两个支脚在发卡主体的宽度方向上相向弯折并连接设置；所述O形导体的两个所述支脚在发卡主体的宽度方向上朝向中部偏转弯折，并在发卡主体的厚度方向上错位间隔设置；所述第一类偏U形导体和第二类偏U形导体与所述O形导体上相邻近的支腿部位于相邻的槽内。
实施例4：与实施例1的主要区别在于，装配状态下，每个定子铁芯槽内具有10个支腿部。
如图29所示，所述发卡导体组包括两个在定子径向上相互间隔地并排设置的第一类偏U形导体和两个在定子径向上相互间隔地并排设置的第二类偏U形导体，以及一个与所述第一类偏U形导体或第二类偏U形导体在定子径向上相互间隔地并排设置的波形导体；所述第一类偏U形导体和第二类偏U形导体上相邻的两个支腿部位于相邻的槽内，且所述第一类偏U形导体的两个支脚在发卡主体的宽度方向上朝向所述第二类偏U形导体偏转弯折，所述第二类偏U形导体的两个支脚在发卡主体的宽度方向上朝向所述第一类偏U形导体偏转弯折。
实施例5：与实施例4的主要区别在于，如图30所示，所述发卡导体组包括在定子周向上错位布置的第一类偏U形导体和第二类偏U形导体，所述第一类偏U形导体和第二类偏U形导体上相邻的两个支腿部位于相邻的槽内，且所述第一类偏U形导体的两个支脚在发卡主体的宽度方向上朝向所述第二类偏U形导体偏转弯折，所述第二类偏U形导体的两个支脚在发卡主体的宽度方向上朝向所述第一类偏U形导体偏转弯折；还包括与所述第一类偏U形导体在定子径向上相互间隔地并排设置的波形导体，以及两个与所述第二类偏U形导体在定子径向上相互间隔地间隔设置的O形导体，两个所述O形导体分别位于所述第二类偏U形导体的两侧。
以上所述仅为本发明的较佳实施例而已，并不以本发明为限制，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
