马达磁铁固定结构 技术领域
本实用新型与马达构造有关, 更详而言之, 系一种马达磁铁固定结构。 背景技术

本实用新型目的在于, 提供一种马达磁铁固定结构, 以改良上述内置式磁铁 阻碍转子组装的问题, 使组装更方便可靠。
本实用新型马达磁铁固定结构, 其特征在于, 包含:
一外壳, 该外壳于相对位置设二磁铁固定部;
一转子, 设于该外壳中;
二可相对该转子提供磁力的磁铁, 分别设于该二磁铁固定部中。
其中, 该磁铁固定部为贯通该外壳壁厚的孔洞。
其中, 该磁铁固定部为一设置在该外壳外表面的凹槽结构。
其中, 该磁铁与该磁铁固定部的相对周边紧制配合固定。
其中, 该磁铁以及该磁铁固定部的至少二周边具有用以构成两者间紧制配合 固定并可对应而接合的斜面构造。
其中, 该磁铁至少二周边对应结合于该磁铁固定部周边的平面结构处, 具有 用以构成两者间紧制配合固定的外圆弧结构。
其中, 一用于对该二磁铁提供一外部约束力量, 进而防止该磁铁脱离该磁铁 固定部的束子, 束套于该外壳的外部。
本实用新型有益效果: 通过上述结构, 因磁铁设置在外壳的外壁, 故可将之 称为外置式磁铁, 而外置式磁铁构造的马达, 可以完全解决先前技术中所述组装 转子困难的问题。
为便于说明本实用新型所表示的中心思想, 兹以具体实施例表达。 实施例中 各种不同物件及其变形量或位移量系按适于例举说明的比例, 而非按实际元件的 比例予以绘制, 合先叙明。 附图说明
图 1为本实用新型第一实施例的立体外观图。
图 2为本实用新型第一实施例的立体分解图。
图 3为本实用新型第一实施例的组合横断面图。
图 4为本实用新型第二实施例的外观图。
图 5为本实用新型第二实施例的立体分解图。 具体实施方式
如图 1、 图 2、 图 3, 本实用新型的马达主要包含一外壳 10、 一转子 11以及二磁 铁 12、 13、 一束子 14。 该外壳 10于相对位置设有一对磁铁固定部 20, 主要功用是 为了容置上述二磁铁 12、 13。 磁铁固定部 20可以如图所示为贯通至该外壳 10内部 的孔洞, 亦可为一种设置在外壳 10外表面的凹槽结构, 而若为凹槽结构, 则该外 壳设置该凹槽后所余留的壁厚仍可使该磁铁 12、 13的磁力透过该壁厚传递至该转 子 11。 图 1、 图 2、 图 3中所示的马达构造更包括了设置在外壳 10尾端的电刷固定座 15及尾盖 16。
组装本实用新型马达的方式是, 先将转子 11设置于该外壳 10中, 再将二磁铁 12、 13分别设置在上述的磁铁固定部 20, 之后将束子 14束套于该外壳 10的外部, 约束该二磁铁 12、 13使其不致脱离该外壳 10。
本实用新型因磁铁 12、 13被设置在外壳 10的外壁, 故可将之称为外置式磁铁, 而外置式磁铁构造的马达, 可以完全避免先前技术中所述组装转子困难的问题。 本实用新型组装时先将转子 11设于外壳 10中, 之后再组装二磁铁 12、 13, 转子 11 组装时由于没有二磁铁的磁力作用, 因此不会发生先前技术中所述卡在外壳上的 问题, 二磁铁 12、 13设于磁铁固定部 20时会与转子 11产生磁吸作用而被吸附定位, 至此马达的磁力构造即组装完成。
如图 4、 图 5, 为本实用新型的另一实施例, 此一实施例的马达主要包含一外 壳 30、 一转子 31以及二磁铁 32、 33、 一束子 34。 该外壳 30于相对位置设有一对磁 铁固定部 40, 主要功用是为了固定上述二磁铁 32、 33。 磁铁固定部 40可以如图所 示为贯通至该外壳 30内部的孔洞, 亦可为一种设置在外壳 30的外表面的凹槽结构, 而若为凹槽结构, 则该外壳 30设置该凹槽后所余留的壁厚仍可使该磁铁 32、 33的 磁力透过该壁厚传递至该转子 31。
组装此一实施例马达的方式则与上一实施例所述者完全相同。 提供图 4、 图 5 结构的用意, 是为了表达该马达外壳及束子的形状可以视实际使用需要而加以改 变的。
兹以第一实施例说明本实用新型其他的细节部份, 该等细节部份亦可应用在 第二实施例中。
该马达 10的磁铁 12、 13设置在磁铁固定部 20时, 除了利用该转子 11与磁铁 12、 13的磁力作用而被吸附固定之外, 该磁铁 12、 13的周边亦与该磁铁固定部 20的周 缘产生定位关系, 在图式中所表现者, 该磁铁 12、 13以及该磁铁固定部 20的至少 二周边具有可对应而接合的斜面构造 21、 131, 使磁铁 12、 13与磁铁固定部 20的周 边发生紧制配合的结合关系, 而使磁铁 12、 13被固定。 除此之外, 该磁铁 12、 13 的至少二周边亦可以为外圆弧结构, 对应磁铁固定部 20周边的平面结构, 同样可 达到紧制结合的固定效果。 该磁铁 12、 13与该磁铁固定部 20周缘的紧制定位关系 亦可以其他任何可能的形式达成。
关于束子 14的应用则视情况而定, 原则上该束子 14可为各种型式, 而不限于 图式所绘者。 束子 14可以提供一该磁铁 12、 13—约束外力, 当马达运转时, 该磁 铁 12、 13即不致因磁斥作用而脱离外壳。 除此之外, 如图所示的束子形状配合材 料的应用, 可达到阻隔磁力向外壳以外的空间释放的功能, 以确保转子与磁铁的 间的相对磁力。
关于本实用新型的外壳 10, 其可为金属制成, 亦可为塑胶制。
虽然本实用新型是以一个最佳实施例做说明, 但精于此技艺者能在不脱离本 实用新型精神与范畴下做各种不同形式的改变。 以上所举实施例仅用以说明本实 用新型而已, 非用以限制本实用新型的范围。 举凡不违本实用新型精神所从事的 种种修改或变化, 倶属本实用新型申请专利范围。
