下面参考图 1描述根据本发明实施例的一种分块定子的制造方法, 所述分块定子例如 可用于单相电容异步电机中。
如图 1所示, 根据本发明实施例的分块定子的制造方法, 包括以下步骤:
Sl、 制造多块定子子铁芯, 每块定子子铁芯形成为拱形工字形形状, 由此可将多块定 子子铁芯适于拼合成整块定子铁芯。
52、 制造多个绝缘的绕线架。
53、 将多个绕线架分别安装至多块定子子铁芯上。
54、 将一部分定子子铁芯上的绕线架上分别缠绕主绕线以形成多个主绕组, 其中多个 主绕组之间的主绕线彼此不连接。
55、 将另一部分定子子铁芯上的绕线架上通过副绕线连续缠绕以形成通过副绕线连接 的多个副绕组, 其中副绕线可以为一根且连续缠绕, 也可以为多根且依次连接, 在此不作
限制。 在每相邻的两个副绕组之间通过过桥线连接, 该过桥线可由副绕线的一部分构成, 也可是单独的一条连接线。
56、 将副绕组和主绕组分别交错排列连接以组成环形形状。
57、 将多个定子子铁芯依次连接。
根据本发明的分块定子的制造方法, 通过由多个定子子铁芯组成整体的定子铁芯, 且 集中绕组, 由此绕线方便且速度快, 同时主绕组和副绕组的组合操作方便, 结构精巧且降 低了制造成本。
步骤 S1中, 每块定子子铁芯的制造包括以下步骤:
Sl l、 冲裁多个铁芯板, 可选地, 铁芯板为电磁钢板。
S12、 将多个铁芯板层积预定层数排列。
S13、 将层积好的多铁芯板进行叠压铆合, 以形成定子子铁芯, 其中定子铁芯包括轭部 和齿部, 其中当多个定子子铁芯装配好后, 相邻两个定子子铁芯的轭部互相配合, 以使多 个定子子铁芯可在周向上形成为整体。
具体地, 如图 6中所示, 根据本发明的一个实施例, 在步骤 S2中, 每个绕线架的制造 包括以下步骤:
S2K 分别制造上框架 21和下框架 22, 其中上框架 21的底端外侧设有上外凹陷位 214 且底端内侧设有上内凹陷位 215, 下框架 22的底端内侧设有下内凹陷位 224且底端外侧设 有下外凹陷位 225;
S22、通过上外凹陷位 214与下外凹陷位 224插接配合, 且上内凹陷位 215与下内凹陷 位 225插接配合可将上框架 21插接在下框架 22的顶部, 如图 4-图 5所示。
根据本发明的一个实施例, 在步骤 S6中, 多个主绕组 A和副绕组 B通过连接架 3装配 成环形形状。 具体地, 连接架 3构造为圆筒形, 其中多个副绕组 B和主绕组 A的绕线架 2 沿连接架 3的周向交错地分布以使副绕组 B和主绕组 A分别交错排列连接以组成环形形状。
如图 10所示, 根据本发明一些具体实施例的分块定子中, 连接架 3的外周面上形成有 周向间隔开的多对定位卡槽 31, 其中每对定位卡槽之间卡持一个绕线架 2。 其中每对定位 卡槽 31包括第一卡槽 311和第二卡槽 312,第一卡槽 311和第二卡槽 312的卡口方向相对, 由此, 第一卡槽 311和第二卡槽 312内可卡持一个绕线架 2, 如图 2、 图 10-图 12中所示。 这样, 通过设置多对定位卡槽 31, 在绕线过程中可有效地固定绕线架 2, 从而固定了多个 定子子铁芯 1, 进而保证了预设计的空间分布形式, 有利于分块定子的组合成型。
进一步地, 根据本发明的一个实施例, 在步骤 S7中, 多个定子子铁芯 1依次相邻定位 后依次焊接。
具体地,如图 4-图 6所示,定子子铁芯 1的两端分别形成有第一定位部 11和第二定位
部 12, 其中一个定子子铁芯 1的第一定位部 11与其相邻的定子子铁芯 1的第二定位部 12 相互配合定位, 如图 3和图 9所示。 可选地, 第一定位部 11形成为从定子子铁芯 1的一端 向外延伸出的突出部,且第二定位部 12为从定子子铁芯 1的另一端向内凹入形成的凹入部。 由此, 使得多个定子子铁芯 1在装配好之后可在周向上平滑过渡, 便于其他部件的安装设 置。 例如, 在本发明的优选实施例中, 步骤 S7中, 还包括: S71、 通过端盖 (图未示出) 将多个定子子铁芯 1定位。 也就是说, 当多个定子子铁芯 1在装配好之后, 端盖套设在多 个定子子铁芯 1的外周面上以对多个定子子铁芯 1给予径向上的压力, 从而使得形成的分 块定子的结构更加稳固可靠。
可选地, 如图 2-图 12所示, 主绕组 A为四个且副绕组 B为四个, 四个主绕组 A和四个 副绕组 B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 2-图 12中, 均显示了四个主绕组 A 和四个副绕组 B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 A和副绕组 B的技术方案 中, 这也落入本发明的保护范围之内。
下面将参考图 2-图 13描述根据本发明实施例的分块定子,所述分块定子由根据本发明 上述实施例中的分块定子的制造方法形成。
如图 2和图 3所示,根据本发明实施例的分块定子包括多块定子子铁芯 1、多个绝缘的 绕线架 2、 连接架 3和接线板 4。
如图 4-图 6中所示, 每块定子子铁芯 1形成为拱形工字形形状。 其中定子铁芯 1包括 轭部 13和齿部 14, 其中当多个定子子铁芯 1装配好后, 相邻两个定子子铁芯 1的轭部 13 互相配合, 以使多个定子子铁芯 1可在周向上形成为整体。
多个绕线架 2分别安装至多块定子子铁芯 1上, 其中一部分绕线架 2上分别缠绕主绕 线 5a以形成主绕线 5a彼此不连接的多个主绕组 A, 每个主绕组 A的顶部设有两个第一插 线针 6a, 主绕线的线头和线尾与两个第一插线针连接。 另一部分绕线架 2上通过副绕线 5 连续缠绕以形成通过副绕线 5b连接的多个副绕组 B, 其中两个相邻的副绕组 B的底部分别 设有第二插线针 6b且副绕线 5b的线头和线尾分别缠绕在所述第二插线针 6b上, 如图 7- 图 9所示。 其中副绕线 5b可以为一根且连续缠绕, 也可以为多根且依次连接, 在此不作限 制。在每相邻的两个副绕组 B之间通过过桥线连接,该过桥线可由副绕线 5b的一部分构成, 也可是单独的一条连接线。
其中主绕组 A的第一插线针 6a和副绕组 B的第二插线针 6b分别通过接线板 4连接。 如图 3和图 13所示。
根据本发明实施例的分块定子, 由于连接架 3将多个绕线架 2连接固定, 保证了预设
计的多个定子子铁芯 1 的空间分布形式, 有利于分块定子的组合成型, 还可使内转子定子 可以采用外转子绕线的方法, 使绕线效率提高了 3倍以上, 同时具有内转子定子接线与抽 头方式少的特点, 能降低接头数量, 提高了生产效率。 根据本发明的分块定子, 结构简单 巧妙, 使用性能好且方便实用。
例如, 如图 2-图 12中所示, 定子子铁芯 1和绕线架 2分别为八个, 且形成四个主绕组
A和四个副绕组 B。
在本发明的一个具体实施例中, 每个绕线架 2包括: 上框架 21和下框架 22, 上框架 21包括上外弧板 211和上内弧板 212,上内弧板 212通过第一连接部 213设在上外弧板 211 的径向内侧, 在本发明的描述中, 径向 "内侧"指的是沿连接架 3的径向方向向内的一侧, 相应地, "外侧"指的是沿连接架 3的径向方向向外的一侧。在上内弧板 212的顶部两端设 有用于绕线 5的绕线柱 2121, 由此为了方便副绕组 B之间的过桥线的缠绕。 上框架 21的 上外弧板 211和上内弧板 212的顶部分别设有两个间隔开中空的第一插线柱 216;
下框架 22包括下外弧板 221和下内弧板 222, 下内弧板 222通过第二连接部 223设在 下外弧板 221的径向内侧。下框架 22的下外弧板 221和下内弧板 222的底部设有两个间隔 开的中空的第二插线柱 226。 其中, 构成主绕组 A的绕线架 2中, 如图 7和图 9所示, 两 个第一插线针 6a分别设在上外弧板 211和上内弧板 212的顶部的第一插线柱 216内, 艮卩, 其中一个第一插线针 6a设在上外弧板 211顶部的一个第一插线柱 216内,而另一个第一插 线针 6a设在上内弧板 212的顶部的第一插线柱 216内。而构成副绕组 B的绕线架 2中, 如 图 8和图 9所示, 两个第二插线针 6b分别设在其中相邻的下框架 22的下内弧板 222底部 的第二插线柱 226内, 其中副绕组 B和主绕组 A分别交错排列连接后, 所述第一插线针和 所述第二插线针位于同一平面上, 且均与接线板连接。
也就是说, 主绕组 A的第一插线针 6a与绕线柱 2121是同向的, 而副绕组 B的第二插 线针 6b则与绕线柱 2121是反向的, 在本发明的分块定子中, 主绕组 A的绕线架 2与副绕 组 B的绕线架 2是反向设置的。 将副绕组 B的第二插线针 6b与绕线柱 2121设置在不同侧 的好处是, 一方面便于接线板 4的布线, 另一方面, 由于副绕组 B是由多条副绕线绕制成 线圈的, 因此副绕组 B之间的过桥线也是多根, 由此, 可以避免当将线头焊接至第二插线 针 6b时, 熔化的焊锡掉落在过桥线上, 将多根过桥线连接在一起造成短路。
其中上框架 21的底端外侧设有上外凹陷位 214且底端内侧设有上内凹陷位 215, 如图 6中所示, 下框架 22的底端内侧设有下内凹陷位 224且底端外侧设有下外凹陷位 225。 上 外凹陷位 214与下外凹陷位 224插接配合以将上外弧板 211的底端插接于下外弧板 221的 顶端, 上内凹陷位 215与下内凹陷位 225插接配合以将上内弧板 212的底端插接于下内弧 板 222的顶端, 由此可将上框架 21插接在下框架 22的顶部, 如图 4-图 5所示。 这样, 每
个绕线架结构中至少包含两个组合为一体的上框架 21与下框架 22。
定子子铁芯 1套设在上框架 21和下框架 22的配合处, 如图 4和图 5所示, 具体地, 定子子铁芯 1的齿部 14内端穿过第一连接部 213和第二连接部 223之间后伸出, 且轭部 13位于上外弧板 211和下外弧板 221外。
优选地, 上外弧板 211和下外弧板 221在上下方向上平齐, 且上内弧板 212和下内弧 板 222在上下方向上平齐, 如图 4和图 5所示, 由此结构整齐且可可靠地固定定子子铁芯 l o
在本发明如图 4-6中示出的实施例中, 定子子铁芯 1的两端分别形成有第一定位部 11 和第二定位部 12, 其中一个定子子铁芯 1的第一定位部 11与其相邻的定子子铁芯 1的第 二定位部 12相互配合定位。 如图 3和图 9所示。 可选地, 第一定位部 11形成为从定子子 铁芯 1的一端向外延伸出的突出部,且第二定位部 12为从定子子铁芯 1的另一端向内凹入 形成的凹入部。 由此, 使得多个定子子铁芯 1在装配好之后可在周向上平滑过渡, 便于其 他部件的安装设置。
在本发明一些实施例中, 分块定子还可包括: 端盖 (图未示出), 端盖套设在多块定子 子铁芯 1的外侧以将多块定子子铁芯 1定位。 也就是说, 当多个定子子铁芯 1在装配好之 后, 端盖套设在多个定子子铁芯 1的外周面上以对多个定子子铁芯 1给予径向上的压力, 从而使得形成的分块定子的结构更加稳固可靠。 进一步地, 分块定子还可包括壳体 (图未 示出), 壳体与端盖配合以限定出多个定子子铁芯 1包覆在其内的腔室。例如壳体和端盖之 间是相互扣合的, 多个定子子铁芯 1装配好并由端盖固定之后, 再由壳体罩上, 由此, 壳 体和端盖还起到了保护分块定子的作用, 例如减少了灰尘等杂质的进入, 延长了分块定子 的寿命。 当然, 本领域内的技术人员可以理解, 电机的转子轴是可穿过壳体和端盖的, 以 便与外部部件相连。
根据本发明实施例的分块定子, 通过多个定子子铁芯 1集中绕组组成, 使内转子定子 可以采用外转子绕线的方法形成, 由此绕线方便且速度快, 使绕线效率提高了 3 倍以上, 同时主绕组 A和副绕组 B的组合操作方便, 结构精巧, 且绕线均匀。 另外, 该分块定子还 具有内转子定子接线与抽头方式少的特点, 能降低接头数量, 提高了生产效率。 根据本发 明实施例的分块定子尤其适用于单速以上的多种速度电机, 适用性高。
根据本发明实施例的一种电机包括: 转子组件 (图未示出) 和分块定子, 其中分块定 子为根据本发明上述实施例中描述的分块定子。 转子组件包括转子轴和设在转子轴上的转 子铁芯。 分块定子套设在转子组件外且转子组件相对于所述分块定子可转动。
其中, 根据本发明实施例的电机的其他构成例如转子铁芯和转子轴等以及操作对于本 领域普通技术人员而言都是已知的, 这里不再详细描述。
根据本发明的电机, 通过采用分块定子, 提高了绕线效率和生产效率, 且操作可靠, 由此提高了电机的运行可靠性。
根据本发明实施例的一种家用电器, 例如变速风扇等, 包括根据本发明上述实施例的 电机。
在本说明书的描述中,参考术语"一个实施例"、 "一些实施例"、 "示意性实施例"、 "示 例"、 "具体示例"、 或 "一些示例"等的描述意指结合该实施例或示例描述的具体特征、 结 构、 材料或者特点包含于本发明的至少一个实施例或示例中。 在本说明书中, 对上述术语 的示意性表述不一定指的是相同的实施例或示例。 而且, 描述的具体特征、 结构、 材料或 者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
