下面结合附图详细描述根据本发明实施例的用于电机的定子组件。
如图 1-6所示,根据本发明实施例的用于电机的定子组件包括定子 10、接线板 40和第 一连接保护层 50。 具体而言, 定子 10进一步包括多个缠线针保持柱 11、 多个缠线针 20和 多个绕组线 30。 多个缠线针保持柱 11在定子 10上间隔布置, 缠线针 20的一端安装在缠 线针保持柱 11上, 绕组线 30的端部缠绕在缠线针 20上形成缠绕部 31。
进一步地, 接线板 40安装在定子 10上, 接线板 40上设有多个与缠线针 20适配的安 装孔 41, 缠线针 20的另一端穿过安装孔 41向外延伸, 第一连接保护层 50包覆在缠线针 20的外周面以及绕组线 30的缠绕部 31上。
也就是说, 定子 10上含有多个缠线针保持柱 11、 多个缠线针 20和多个绕组线 30。 缠 线针保持柱 11分开设置在定子 10上, 缠线针保持柱 11上设有缠线针安装孔, 缠线针 20 的一端插入到缠线针保持柱 11 的缠线针安装孔中, 且缠线针安装孔的深度小于缠线针 20 的长度, 使得缠线针 20—端插入到缠线针保持柱 11上的同时, 缠线针 20的另一端能够伸 出缠线针保持柱 11, 以利于后续绕组线 30和接线板 40的安装。
可以理解的是, 由于缠线针 20要安装在缠线针保持柱 11上, 因此, 缠线针保持柱 11 的数量要大于或者等于缠线针 20的数量。同时接线板 40上安装孔 41的分布情况要与缠线 针 20的分布相匹配, 以使缠线针 20能够与接线板 40配合安装在一起。
由于绕组线 30的另一端缠绕在缠线针 20上形成缠绕部 31, 因此, 可以理解是, 当缠 线针 20的另一端安装在接线板 40的安装孔 41上时,缠线针 20连同其上的缠绕部 31的截 面直径应大于安装孔 41的直径, 以使缠线针 20能够容易地插入到接线板 40的安装孔 41 上。
而当缠线针 20连同其上的缠绕部 31与连接板 40组合在一起时, 缠线针 20与缠绕部
31会暴露于外界而无保护, 使用寿命受到影响。 而第一连接保护层 50的设置能够对缠线 针 20和绕组线 30起到良好的保护作用, 有效地延长使用寿命。
即根据本发明实施例的用于电机的定子组件, 通过在缠线针 20和绕组线 30的缠绕部
31上设置第一连接保护层 50, 使缠线针 20和绕组线 30的缠绕部 31连接, 同时与外界隔 离而不易被氧化, 使用性能大大提高, 使用寿命有所延长, 该定子组件设计巧妙、 结构简 捷、 加工容易且方便实用。
需要说明的是,定子 10上的缠线针保持柱 11的具体安装位置可以根据定子 10的结构 进行具体调整。 可选地, 根据本发明的一个实施例, 定子 10还包括多个分块铁芯 13和多 个绝缘框架 12, 多个分块铁芯 13首尾相接拼合成封闭环状结构, 多个绝缘框架 12分别设 置在多个分块铁芯 13上, 缠线针保持柱 11设置于绝缘框架 12上, 绕组线 30缠绕于绝缘 框架 12上, 如图 1所示。
也就是说, 分块铁芯 13首尾相接构成定子 10的骨架结构, 多个绝缘框架 12位于多个 分块铁芯 13上, 绕组线 30缠绕在绝缘框架 12上时也将分块铁芯 13缠绕住。 同时在绝缘 框架 12上间隔设置了多个缠线针保持柱 11, 并将缠线针 20安装在上面, 绕组线 30的一 端缠绕在缠线针 20上形成缠绕部 31, 绕组线 30的另一端缠绕在绝缘框架 12和分块铁芯
13上。 可以理解的是, 由于绝缘框架 12安装在分块铁芯 13上, 为了保证定子 10具有良 好的性能, 绝缘框架 12的结构要与分块铁芯 13的结构适配。 根据本发明的一个实施例, 绕组线 30为铝线, 绕组线 30的缠绕部 31为脱皮铝线, 缠 线针 20为镀锡缠线针, 第一连接保护层 50为锡层。 由此, 缠绕部 31缠绕在镀锡缠线针上 且又被锡层包覆。 换言之, 脱皮铝线位于两层锡层之间, 锡层能够对脱皮铝线起到良好的 隔离保护作用, 使得脱皮铝线不易被氧化, 同时由于锡层具有导电性, 使得脱皮铝线在被 隔离的同时能够导电。 另外, 在缠线针 20上镀锡也能够使缠线针 20的耐蚀能力增强。
需要说明的是, 第一连接保护层 50设置为锡层, 其可以通过将缠绕有绕组线 30的缠 线针 20放在高温锡炉中浸锡或者锡焊形成。 通过该方式形成第一连接保护层 50, 绕组线 30在缠绕到缠线针 20上形成缠绕部 31之前无需预先进行脱皮处理, 绕组线 30缠绕到缠 线针 20上之后, 将其进行高温浸锡或者锡焊时, 缠绕部 31在高温下便可脱皮, 简化了定 子组件的装配过程。 另外, 第一连接保护层 50为锡层, 通过浸锡或者锡焊处理缠线针 20 以及缠绕部 31, 不仅可以将缠绕部 31固定连接在缠线针 20上, 还可以保护缠绕部 31的 脱皮铝线不易被氧化, 起到固定和保护缠绕部 31的双重作用。
容易理解的是, 为了达到导电的目的, 将缠绕部 31形成为脱皮铝线, 而绕组线 30上 与缠绕部 31相连的部分则为漆包铝线, 以起到保护内部铝线、与其他部件绝缘和使用安全 的效果。 在使用中, 此部分漆包的铝线很容易发生破损或脱皮而使内部的铝线暴露出来, 进而使铝线被氧化, 使用性能有所降低。
为了避免这种情况的发生, 可选地, 根据本发明的一个实施例, 用于电机的定子组件 还包括多个保护套 60, 每个保护套 60分别套设在缠线针保持柱 11上, 保护套 60的径向 尺寸和轴向尺寸分别大于缠线针保持柱 11的径向尺寸和轴向尺寸, 每个保护套 60的内周 壁与缠线针保持柱 11的外周壁以及缠线针 20的至少一部分之间形成装配间隙。
由此, 与缠绕部 31相连的绕组线 30上的漆包铝线就能够设在装配间隙内, 保护套 60 能够对此部分漆包铝线起到良好的保护作用, 使其不易发生破损或脱皮, 进而不会使其内 部的铝线受到氧化。 同时, 保护套 60也能够对缠线针 20保持柱 11和缠线针 20起到良好 的遮挡和保护作用, 并使缠线针 20在缠线针保持柱 11上的安装更为稳固。
可以理解的是, 对于套设缠线针保持柱 11的保护套 60的具体结构不做特殊限制, 可 以为单个圆筒状或者椭圆状, 也可以是几个圆筒状或者椭圆状连接在一起, 可以将一个缠 线针保持柱 11套住, 也可以将多个缠线针保持柱 11共同套设在一起。
可选地, 根据本发明的一个实施例, 定子 10的截面大体形成为环形, 多个缠线针保持 柱 11沿定子 10的周向间隔开布置, 多个保护套 60相连形成为一体的环形结构。 由此, 一 体结构的环形保护套 60能够将多个间隔的缠线针保持柱 11同时保护住并将其固连在一起, 使得定子 10可以采用外转子绕线和内转子定子接线的方法, 使绕线的效率提高三倍以上, 且抽头方式变少, 接头的数量减少, 生产制作效率有所提高。 考虑到在将绕组线 30上的缠绕部 31与缠线针 20固定时采用了高温浸锡或者锡焊的方 式, 绕组线 30上除了缠绕部 31之外的其他部分, 尤其是邻近缠绕部 31的部分在高温作用 下, 也有可能会部分脱皮, 从而使绕组线 30上出现一段部分脱皮的过渡段, 该过渡段形成 在绕组线 30与缠绕部 31之间且位于保护套 60与缠线针保持柱 11以及缠线针 20形成的装 配间隙内。
而过渡段的结构同样存在容易被氧化的问题, 为了对绕组线 30上过渡段的结构进行保 护, 可选地, 根据本发明的一个示例, 用于电机的定子组件还包括过渡段保护层 70, 过渡 段保护层 70设在装配间隙内以包覆缠绕部 31的至少一部分。 也就是说, 过渡段保护层 70 位于装配间隙内, 将漆包铝线和缠绕部 31 的至少一部分包裹住。 由此, 过渡段保护层 70 能够对漆包铝线和与漆包铝线相连的脱皮铝线起到固定和隔离外界空气和水分的作用, 使 得漆包铝线不易发生破皮, 其内的铝线不易被氧化, 且与之相连缠绕部 31的脱皮铝线也不 易被氧化。
可选地, 根据本发明的一个实施例, 过渡段保护层 70为注胶层或注塑层。 由此, 注胶 层和注塑层能够起到良好的隔离空气和水分的效果, 对铝线起到良好的保护作用。 可以理 解的是, 过渡段保护层 70不仅限于此, 也可以是其他隔离空气和水分的材料层, 例如橡胶 层。
根据本发明的一个实施例, 安装孔 41的径向尺寸大于缠线针 20上第一连接保护层 50 的径向尺寸, 第一连接保护层 50与安装孔 41之间设有第二连接保护层 80。 由此, 当缠线 针 20上缠绕上绕组线 30后仍能够将其安装在接线板 40的安装孔 41上。 并且第二连接保 护层 80能够对缠线针 20和缠绕部 31起到进一步地保护作用。
具体地, 根据本发明的一个实施例, 接线板 40为铜箔接线板, 第二连接保护层 80为 锡层。 由此, 锡层能够对缠线针 20和其上的脱皮铝线起到进一步地保护作用, 同时又能够 保证缠线针 20、 缠绕部 31的脱皮铝线与接线板 40之间能够导电。
另外, 对于第二连接保护层 80的制备方式不做要求。 可选地, 根据本发明的一个实施 例, 第二连接保护层 80通过浸锡或焊接形成。 换言之, 可以将缠线针 20和缠绕在其上的 脱皮铝线放入到高温锡炉中通过浸锡固连在一起或者使用焊枪进行锡焊接以将缠线针 20 和其上的脱皮铝线固定在一起, 这两种制备方法均是可以方便实施的。
需要说明的是, 将第二连接保护层 80的设置成锡层, 其成型方式以及技术效果与上述 实施例的第一连接保护层 50的成型方式以及技术效果类似,即均可通过高温浸锡或者锡焊 的方式成型, 可以起到连接接线板 40和缠线针 20的作用, 也能够起到进一步保护缠线针 20的作用。 下面具体描述根据本发明实施例的用于电机的定子组件的制备方法。 其中, 用于电机 的定子组件可以为本发明上述实施例中的用于电机的定子组件, 也可以为其他结构形式的 定子组件。 当使用根据本发明实施例的用于电机的定子组件的制备方法制备本发明上述实 施例中的用于电机的定子组件时, 可包括如下步骤:
首先组装定子 10。 具体来说, 先将多个缠线针保持柱 11间隔设置在定子 10上, 再将 多个缠线针 20分别安装在多个缠线针保持柱 11上,然后将每个绕组线 30的端部缠绕在缠 线针 20上形成缠绕部 31。 然后将组装后的定子 10局部浸锡, 以形成包覆缠线针 20的外 周面以及绕组线 30的缠绕部 31的第一连接保护层 50, 可以理解的是, 由于采用的是浸锡 处理的方法, 因此第一连接保护层 50 为锡层。 并且, 在本发明的一个实施例中, 绕组线 30为漆包铝线, 以起到绕组线 30之间相互绝缘和保护铝线的作用。
另外, 对于包含多个分块铁芯 13和多个绝缘框架 12的定子 10而言, 由于缠线针保持 柱 11要安装在绝缘框架 12上, 因此, 在组装定子 10时, 需首先组装分块铁芯 13和绝缘 框架 12, 具体地, 根据本发明的一个实施例, 先将多个绝缘框架 12 固定在对应的分块铁 芯 13上, 在绝缘框架 12上的缠线针保持柱 11上插入缠线针 20, 然后在绝缘框架 12上缠 绕绕组线 30, 最后将多个安装有绝缘框架 12的分块铁芯 13首尾拼接, 即可完成定子 10 的初步装配。
进一步地, 根据本发明的一个实施例, 用于电机的定子组件的制备方法还包括如下步 骤:
在缠线针保持柱 11外套设保护套 60, 并使每个保护套 60的内周壁与缠线针保持柱 11 的外周壁以及缠线针 20的至少一部分之间形成装配间隙。 然后在装配间隙内注胶或注塑, 以形成包覆缠绕部 31的至少一部分的过渡段保护层 70。
将定子 10组装完成之后, 即可将其与接线板 40安装在一起,对于定子 10与接线板 40 的装配方法不做特殊限制。 可选地, 根据本发明的一个实施例, 用于电机的定子组件的制 备方法可包括如下步骤:
将组装后的定子 10与接线板 40连接,将缠线针 20穿过接线板 40上的安装孔 41向外 延伸。 然后在第一连接保护层 50与安装孔 41之间设置第二连接保护层 80, 其中, 第二连 接保护层 80也可为锡层。 由此, 用于电机的定子组件即可装配完成。
根据本发明实施例的用于电机的定子组件的其他构成及其制备方法对于本领域普通技 术人员而言都是已知的, 这里不再详细描述。
在本说明书的描述中,参考术语"一个实施例"、 "一些实施例"、 "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。
尽管上面已经示出和描述了本发明的实施例, 可以理解的是, 上述实施例是示例性的, 不能理解为对本发明的限制, 本领域的普通技术人员在不脱离本发明的原理和宗旨的情况 下在本发明的范围内可以对上述实施例进行变化、 修改、 替换和变型。
