Description

稀土永磁无铁芯发电机组
【技术领域】
本发明涉及一种由发动机驱动型发电机组，特别是涉及一种稀土永磁无铁芯发电机组。
【背景技术】
现有技术发动机驱动的发电机组中，发电机定子与发动机曲轴同轴安装，发电机定子直接装配在发动机的箱体或者侧盖等部件上。壳式结构的外转子装配在发动机的曲轴的动力输出端，其壳口方向朝向发动机和发电机定子。外转子的壳体背部安装冷却风扇，用于冷却发电机定子、转子及其它部件。由于这种发电机的发电机定子位于发动机与发电机转子壳体之间，尽管其与发动机之间留出隔热空间，但发电机运行产生的热量还是会辐射到发电机定子上，导致发电机电能输出效率降低，发电机输出电缆由于受热易老化，发电机定子维修复杂等技术问题。
【发明内容】
基于此，有必要提供一种发热较小，发电机电能输出效率较高的发电机组。
一种稀土永磁无铁芯发电机组，包括：
机架；
发动机，固定在该机架上，该发动机包括输出轴；
发电机，包括：
发电机座板，固定在该发动机上；
发电机外壳，固定在该发电机座板上；
定子，固定在该发电机外壳上，包括盘式绕组和包覆该盘式绕组的由高分子聚合物形成的固定外壳；
第一挡磁板，通过平键固定在该输出轴上，且位于该定子和该发电机座板之间，并限定出吸气腔室和排气腔室，该第一挡磁板上靠近该输出轴的位置开设有连接该吸气腔室和该排气腔室的第一导气口；
第二挡磁板，通过平键固定在该输出轴上，位于该定子远离该第一挡磁板的一侧；
多个稀土永磁铁，通过永磁体压块固定在该第一挡磁板和该第二挡磁板上，并与该定子相对应；
筋叶，固定在该第一挡磁板上靠近该发电机座板的一侧；
散热风扇，固定在该第二挡磁板远离该永磁体压块的一侧；及
导流罩，固定在该发电机外壳上；
逆变器，固定在该机架上，与该负载单元电性连接；及
输出电源箱，固定在该机架上，与该逆变器电性连接。
在优选的实施例中，该发动机为柴油机、汽油机、燃气轮机、水力机或风力机。
在优选的实施例中，该第二挡磁板上靠近该输出轴的位置开设有第二导气口。
在优选的实施例中，该盘式绕组包括径向与周向交叉绕制的铜线。
在优选的实施例中，该第一挡磁板和第二挡磁板的形状为凹凸型的圆盘。
在优选的实施例中，每一稀土永磁铁的截面形状为梯形，该多个稀土永磁铁对称分布于该第一挡磁板和该第二挡磁板上。
当上述稀土永磁无铁芯发电机组的发动机驱动输出轴旋转时，筋叶能够搅动发电机内的气流，使其在径向产生压力差，使得空气从吸气腔室通过第一导气口流向排气腔室，定子产生的一部分热量被带到排气腔室散热，同时空气流动使得热量与外壁的传递更加充分，起到降低发电机的工作温度、提高发动机的输出功率的功能。
【附图说明】
通过附图中所示的本发明的优选实施例的更具体说明，本发明的上述及其它目的、特征和优势将更加清晰。在全部附图中相同的附图标记指示相同的部分。并未刻意按实际尺寸等比例缩放绘制附图，重点在于示出本发明的主旨。
图 1 为一实施例的稀土永磁无铁芯发电机组的立体组装示意图；
图 2 为图 1 所示发动机和发电机的剖面示意图；
图 3 为图 2 中第一挡磁板和稀土永磁铁的侧视图。
【具体实施方式】
为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合附图对本发明的具体实施方式做详细的说明。在下面的描述中阐述了很多具体细节以便于充分理解本发明。但是本发明能够以很多不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本发明内涵的情况下做类似推广，因此本发明不受下面公开的具体实施的限制。
其次，本发明利用示意图进行详细描述，在详述本发明实施例时，为便于说明，表示器件结构的剖面图会不依一般比例作局部放大，而且所述示意图只是实例，其在此不应限制本发明保护的范围。此外，在实际制作中应包含长度、宽度及深度的三维空间尺寸。
请参阅图 1 ，一实施例的稀土永磁无铁芯发电机组 100 包括机架 101 、发动机 102 、发电机 103 、逆变器 104 、输出电源箱 105 、手柄 106 、减振胶垫 107 和覆盖面板 108 。
机架 101 由金属管弯曲形成。发动机 102 通过减振胶垫 107 和螺栓固定于机架 101 。本实施例中，发动机 102 为柴油机。可以理解，发动机 102 也可为汽油机、燃气轮机、水力机或风力机。发电机 103 通过螺栓固定于发动机 102 。
逆变器 104 和输出电源箱 105 通过螺栓固定于机架 101 上，并通过导线（图未示）与发电机 103 电性连接，用于电流的稳定输出。
手柄 106 可旋转地设置于机架 101 上，以利于整体搬运。覆盖面板 108 设置于机架 101 的顶部，用于遮蔽其下方的发动机 102 等元件。
请参阅图 2 ，其为发动机 102 和发电机 103 的剖面示意图。发动机 102 包括端盖 1 和从端盖 1 穿出的可旋转的输出轴 22 。
发电机 103 包括发电机座板 2 、螺钉 3 、发电机外壳 4 、螺钉 5 、螺钉 6 、导流罩 7 、螺钉 8 、定子 9 、永磁片压块 10 、多个稀土永磁铁 11 、螺钉 12 、筋叶 13 、散热风扇 14 、盘式绕组 15 、固定外壳 16 、第一挡磁板 171 、第二挡磁板 172 、压盖 19 、螺钉 20 、平键 21 、柴油机输出轴 22 和隔套 23 。
发电机座板 2 通过螺钉 3 固定在发动机 102 的端盖 1 上。
发电机外壳 4 大致为一环形管，其通过螺钉 6 固定在发电机座板 2 上，并将定子 9 固定在其内部。
导流罩 7 通过螺钉 8 固定在发电机外壳 4 上，形成一个收容转子和定子的空间。
定子 9 通过轴线的任一截面大致为'工'字形，其包括盘式绕组 15 和包覆该盘式绕组 15 的由高分子聚合物形成的固定外壳 16 。固定外壳 16 的作用是将绕制好的盘式绕组 15 通过具有良好的导热性能、强度的高分子聚合物材料将其固定，形成稳定的盘式定子结构。盘式绕组 15 通过导线与逆变器 104 相连。盘式绕组 15 采用径向与周向交叉绕制的铜线，以使径向铜线有效切割轴向垂直磁感线。
第一挡磁板 171 采用导磁材料制成，其形状为凹凸型的圆盘。第一挡磁板 171 通过平键 21 固定在输出轴 22 上，且位于定子 9 和发电机座板 2 之间。第一挡磁板 171 将定子 9 和发电机座板 2 之间的空间限定成靠近定子 9 的吸气腔室 24 和靠近发电机座板 2 的排气腔室 25 。第一挡磁板 171 上靠近输出轴 22 的位置开设有连接该吸气腔室 24 和该排气腔室 25 的第一导气口 181 。
筋叶 13 通过螺钉固定在第一挡磁板 171 上靠近发电机座板 2 的一侧，即位于排气腔室 25 内。筋叶 13 为金属或非金属材料制成的有一定面积的扇叶结构。筋叶 13 的作用是搅动发电机 103 内的气流，使其在径向产生压力差，使得空气从吸气腔室 24 通过第一导气口 181 流向排气腔室 25 ，定子 9 产生的一部分热量被带到排气腔室 25 散热，同时空气流动使得热量与外壁的传递更加充分，起到降低发电机 103 的工作温度、提高发动机的输出功率的功能。
第二挡磁板 172 的结构与第一挡磁板 171 较为相似，其通过平键 21 、隔套 23 、压盖 19 及螺钉 20 固定在输出轴 22 上，且位于定子 9 远离第一挡磁板 171 的一侧。第二挡磁板 172 上靠近输出轴 22 的位置开设有第二导气口 182 。
散热风扇 14 通过螺钉 12 固定在第二挡磁板 172 远离永磁体压块 10 的一侧，作用与筋叶 13 相似。
多个稀土永磁铁 11 通过永磁片压块 10 和螺钉 5 固定在第一挡磁板 171 和第二挡磁板 172 上，并与定子 9 相对应。永磁片压块 10 由非导磁材料制成。请参阅图 3 ，每一稀土永磁铁 11 的截面形状为梯形。多个稀土永磁铁 11 对称分布于第一挡磁板 171 和第二挡磁板 172 上，且相邻磁铁的极性相反，以使磁感线更为集中。稀土永磁铁 11 为稀土金属和过渡族金属形成的合金经一定的工艺制成的永磁材料，例如钕铁硼（ NdFeB ）永磁材料。
使用时，发动机 102 驱动输出轴 22 旋转，从而使得稀土永磁铁 11 随第一挡磁板 171 和第二挡磁板 172 一起旋转。定子 9 内的盘式绕组 15 在磁场中做切割磁感线的运动，进而产生感应电动势。盘式绕组 15 产生的电流由导线传输至逆变器 104 进行适当转换，最后进入输出电源箱 105 供后续使用。
上述稀土永磁无铁芯发电机组具有以下优点：
１） 发电机与发动机紧密连接牢固，节省空间。
２） 稀土永磁铁与第一、二挡磁板连接可靠。
３） 组装工艺简单。
４） 气隙小，提高了磁能利用率。
５） 定子由盘式线圈绕组构成，无铁芯，发热较小。
６） 发电机效率高。
７） 输出转矩大。
８） 无齿槽效应，转速平稳。
９） 发电机的散热效果优良。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
