Description

分块定子及其制造方法、电机 技术领域
本发明涉及电机制造技术领域，尤其是涉及一种分块定子及其制造方法、电机。
背景技术
相关技术中指出，电机的调速方式一般采用副绕组抽头方式和电容调速方式。副绕组抽头方式主要是通过改变电机的气隙磁场的大小及椭圆度来实现调速的目的。然而，副绕组抽头方式存在如下缺陷：电机要实现N’挡调速，就必须做N’-1个抽头，在工艺上需要过N’个跨江线，电机的档位越大，跨江线的数量就越多，生产效率普遍明显降低，同时由于各跨江线是利用绕线架上的过线柱实现过线连接，每条跨江线相互紧贴，存在匝间短路的隐患。由于该方式的上述缺陷，电机一般只能实现4挡调速。
而电容调速方式主要是通过利用电容降压来实现调速。然而，电容调速方式成本高，同时需要增加电容接线的工序。目前很多厂家都是采用这两种方式结合使用，一般能够实现8挡调速，高于8挡的电机在制作工艺上很难实现，同时成本比较高。

下面参考图1-图8描述根据本发明实施例的分块定子100的制造方法。其中，分块定子100例如可以用于单相电容异步电机中。
具体而言，分块定子100包括多个主绕组B和多个付绕组A，每个主绕组B和付绕组A均包括分块铁芯11和设在分块铁芯11上的绕线架12，主绕组B和付绕组A的分块铁芯11沿周向交错分布且互相连接以形成环形形状，从而使多个分块铁芯11拼合成整个定子铁芯。主绕组B和付绕组A的绕线架12上分别绕设有主绕线14和付绕线13。
绕线架12上设有多个缠针121，主绕线14或付绕线13的线头131或线尾132可以缠绕在相应的绕线架12的缠针121上。当电机需要换挡调速时，付绕线13还可以具有抽头133，抽头133也可以缠绕在相应的绕线架12的缠针121上。这里，需要说明的是，“抽头133”可以理解为由付绕组A抽出供接线用的线头131，抽头133接在电路中，每个抽头133所对应的线圈的匝数不一样，进而能满足一个电路中对电感的不同的要求。可以理解，缠针121的个数以及在绕线架12上的布置方式等可以根据实际需求而适应性改变，本发明对此不作具体限定。
参照图7并结合图1-图6，根据本发明第一方面实施例的分块定子100的制造方法，包括以下步骤：
S1、将付绕线13绕制在多个付绕组A的绕线架12上，付绕线13具有至少一个抽头133，至少一个抽头133绕制在多个付绕组A中的至少一个绕线架12的至少一个缠针121上，其中多个付绕组A的分块铁芯11依次通过一个跨江线134连接；
S2、将主绕线14绕制在多个主绕组B的绕线架12上；以及
S3、将步骤S2中的绕制有主绕线14的多个主绕组B中的每一个插入步骤S1中的绕制有付绕线13的多个付绕组A中的每相邻的两个之间以构成分块定子100。
这里，需要说明的是，在步骤S1中，“多个付绕组A的分块铁芯11依次通过一个跨江线134连接”，例如，如图2所示，可以理解为在分块定子100的周向上，相邻的两个付绕组A的分块铁芯11之间只通过一个跨江线134连接，且多个付绕组A中的第一个(例如，图2中所示的上方的付绕组A)与最后一个(例如，图2中所示的左侧的付绕组A)不通过跨江线134连接。其中，当多个付绕组A依次通过一根付绕线13连续绕制(即连绕方式)时，“多个付绕组A中的第一个”可以理解为付绕线13绕制的第一个付绕组A，“多个付绕组A中的最后一个”可以理解为付绕线13绕制的最后一 个付绕组A。
可选地，参照图4，分块铁芯11具有过线柱122，其中跨江线134的两端分别连接在相邻的两个分块铁芯11的过线柱122上。
抽头133的个数可以根据挡位数量的不同而适应性改变。电机需要实现N挡调速，就需要N-1个抽头133，每个抽头133对应的线圈的匝数可以由每挡速度的大小来确定。例如，电机需要实现三挡调速，此时需要做两个抽头133，图1中的H、M、L分别表示三个挡位。其中，两个抽头133可以分别缠绕在多个付绕组A的不同绕线架12的缠针121上，也可以缠绕在同一个绕线架12的不同缠针121上。
可以理解的是，步骤S1和步骤S2可以同时也进行，也可以先后进行。其中，步骤S1和步骤S2的先后顺序可以根据实际要求而适应性调整，本发明对此不作具体限定。
进一步地，如图8所示，在步骤S3之后，分块定子100的制造方法还包括：
S4、将接线板2安装在多个主绕组B和多个付绕组A上，其中缠针121的自由端(即远离分块铁芯11的一端)穿过接线板2。
根据本发明实施例的分块定子100的制造方法，通过将多个付绕组A的分块铁芯11设置为依次通过一个跨江线134连接，提高了分块定子100的绕线效率，且降低了分块定子100的制造和材料成本。当该分块定子100应用于电机上时，在保证电机性能不变的前提下，可以提高绕线效率达20％以上，且挡位越多，提升效果越明显。
如图1-图7的实施例中，主绕组B为四个、且付绕组A为四个，四个主绕组B和四个付绕组A分别交错设置。然而，应当注意的是，在本申请的描述中，以及图1-图7中，均显示了四个主绕组B和四个付绕组A用于示例说明的目的，但是普通技术人员在阅读了本申请说明书中的技术方案之后、显然可以理解将该方案应用到更少或者更多个主绕组B和付绕组A的技术方案中，这也落入本发明的保护范围之内。
根据本发明的一个具体实施例，步骤S1具体包括：
S11、将付绕线13的线头131绕制在多个付绕组A中的第一个的绕线架12的缠针121上；
S12、将付绕线13绕制在多个付绕组A中的第一个的绕线架12上，并在周向上沿顺时针或逆时针方向将付绕线13依次绕制在多个付绕组A中的其余绕线架12上；
S13、将付绕线13的线尾132绕制在多个付绕组A中的最后一个的绕线架12的缠针121上。
其中，在步骤S11中，“多个付绕组A中的第一个”可以是多个付绕组A中的任意一个付绕组A，也就是说，以多个付绕组A中的任意一个付绕组A为第一个。
多个付绕组A绕线时，首先，将付绕线13的线头131缠绕在上述第一个付绕组A的绕线架12的缠针121上；然后，将付绕线13缠绕在该第一个付绕组A的绕线架12上，接着在分块定子100的周向上例如沿图2中的顺时针方向将付绕线13依次缠绕在其余的付绕组A的绕线架12上；在付绕线13绕至最后一个付绕组A的绕线架12上后，将付绕线13的线尾132缠绕在该最后一个付绕组A的绕线架12的缠针121上。
进一步地，步骤S12具体包括：
S121、付绕线13在多个付绕组A中的任意一个的绕线架12上绕制一定匝数后，将付绕线13绕制在绕线架12的缠针121上以构成抽头133；
S122、将付绕线13继续绕制在多个付绕组A中的任意一个的绕线架12上或多个付绕组A中的下一个的绕线架12上。
例如，参照图2并结合图1，在将付绕线13的线头131缠绕至上述第一个付绕组A的绕线架12的其中一个缠针121上后，可以将付绕线13在该第一个付绕组A的绕线架12上绕制一定匝数，接着将付绕线13缠绕在该绕线架12的另一个缠针121上以形成抽头133，然后继续将付绕线13绕制在该第一个付绕组A的绕线架12上，并沿顺时针方向将付绕线13依次绕制在其余的付绕组A的绕线架12上，在付绕线13绕制最后一个付绕组A的绕线架12的过程中，可以先将付绕线13在该最后一个付绕组A的绕线架12上绕制一定匝数，接着将付绕线13缠绕在该绕线架12的其中一个缠针121上以形成另一个抽头133，然后继续将付绕线13绕制在该最后一个付绕组A的绕线架12上，最后将付绕线13的线尾132缠绕在该绕线架12的另一个缠针121上。其中，付绕线13从一个付绕组A到下一个付绕组A之间的部分可以理解为跨江线134。图2中的第一个付绕组A至最后一个付绕组A(顺时针方向)依次为付绕组A1、付绕组A2、付绕组A3、付绕组A4。可以理解，抽头133在多个付绕组A上的具体布置方式以及对应的线圈的匝数等可以根据实际要求而适应性改变，本发明对此不作特殊限定。
由此可知，当每个分块铁芯11的缠针121的个数为M时，付绕线13的线头131和线尾132所在的分块铁芯11可以抽M-1个抽头133，其它分块铁芯11可以抽M个抽头133。从而当付绕组A个数为四时，可以实现最多4×M-1个挡位。但无论M取何值，付绕线13绕制过程中只需过一次跨江线134。
根据本发明的一个具体实施例，步骤S2具体包括：
S21、将多个主绕线14分别绕制在多个主绕组B的绕线架12上。此时多个主绕线14与多个主绕组B的绕线架12一一对应。
例如，如图5和图6所示，各个主绕组B分别采用独立绕线方式，每个主绕线14 缠绕在对应的主绕组B的绕线架12上，且每个主绕线14的线头131和线尾132缠绕在同一个绕线架12的两个缠针121上。绕制完毕后的各个主绕组B是彼此独立的。其中，图5中的第一个主绕组B至最后一个主绕组B(顺时针方向)依次为主绕组BB1、主绕组BB2、主绕组BB3、主绕组BB4。
根据本发明实施例的分块定子100的制造方法，实现了一种新的抽头133调速方式，针对电机的各个挡位调速只需过一次跨江线134，从而不存在匝间短路的隐患，且可以实现更多挡位的调速。
如图7和图8所示，根据本发明第二方面实施例的分块定子100，分块定子100采用根据本发明上述第一方面实施例的分块定子100的制造方法制造而成。
根据本发明实施例的分块定子100，通过采用根据本发明上述第一方面实施例的分块定子100的制造方法，提高了分块定子100的装配效率，且降低了分块定子100的成本。
根据本发明第三方面实施例的电机，包括：转子和根据本发明上述第二方面实施例的分块定子100。其中，分块定子100套设在转子外，且转子相对于分块定子100可转动。
根据本发明实施例的电机，通过采用根据本发明上述第二方面实施例的分块定子100，在保证电机性能不变的前提下，极大地提高了电机的装配效率，且降低了电机的制造和材料成本，且电机可以实现更多挡位调速，。
根据本发明实施例的电机的其他构成等以及操作对于本领域技术人员而言都是已知的，这里不再详细描述。
