二极电机 技术领域
本发明涉及一种电机， 尤其是一种多用途的二极电机。 背景技术
现有技术的电动机大多采用单定子单转子电机， 这种结构的电动机通 常只是在一个工作状态下工作， 比较适合负载相对固定的工作场合， 对于 负载变化较大的工作场合， 常常会导致设备的浪费。 而对于发电机来说， 这一问题同样存在， 只不过发电机所要求的是恒定的输入转矩， 在输入转 矩时大时小的状态下， 现有技术的发电机很难稳定发电。 公开日为 2007年 8月 15日、公开号为 CN101017998A的专利文件公开了一种直驱式混合励磁 双定子风力发电机， 是一种定子空间大、 低速高输出电压、 实时捕获最大 风能的风力发电机， 该发电机的定子为双定子， 双定子部分包括内定子、 外定子和内定子支架； 电励磁绕组部分包括电励磁绕组和励磁绕组支架； 转子包括杯形转子、 内永磁体、 外永磁体、 转子背轭和转轴； 该电机取消 了齿轮箱， 采用双定子结构提高了功率密度， 通过调节励磁电流的大小和 方向可方便地调节气隙磁场的大小， 调节电机转速， 捕获最大风能。 公开 日为 2009年 6月 24日、公开号为 CN101465584A的专利文件公开了一种双 定子无刷直流电机及其制动方法， 包括嵌入了磁场绕组的第一定子、 空心 杯转子和转子位置传感器， 还包括设置在所述空心杯转子内腔的第二定子， 该第二定子的一端轴伸穿出所述空心杯转子在同一端的密封盖固定在电机
的一个端盖的中央部位， 另一端则借助轴承可转动地支承在所述空心杯转 子主轴的内端同轴线镶嵌的细轴上； 所述第二定子上设置有励磁绕组， 其 电线束从该第二定子的一端空心轴伸内腔穿出， 用于在制动时供电。 该结 构的有益效果在于： 只需要消耗较小的能量就可以产生较大的制动力矩， 实现高效、 高精度的制动方式以及姿态调整与保持。 上述两种结构的双定 子电机的转子均采用永磁磁体结构， 其缺点是磁体产生的磁场强度是固定 的， 无法根据实际工作需要加以调整， 影响了电机的使用范围。 发明的公开
本发明的目的是为解决现有技术的电动机功率固定， 不适合负载变化 较大的工作场合的问题而提供一种功率可变、 可以在变化较大的负载下正 常工作的二极电机。
本发明的另一目的是为解决现有发电机存在的输入转矩变化较大时无 法正常工作的问题而提供一种可以在变化较大的输入转矩下正常工作的二 极电机。
本发明为达到上述技术目的所采用的具体技术方案为： 一种二极电机， 包括内极定子与外极定子， 内极定子与外极定子之间设有转子， 所述的转 子包括转子架及输出轴， 转子架上设有永磁磁钢或电磁线圈， 内极定子的 轴心线上设有固定轴， 内极定子与外极定子上均设有绕组， 外极定子上的 绕组数量大于内极定子， 内极定子绕组、 电磁线圈及外极定子绕组均连接 电机控制器， 电机控制器控制电机的工作状态和电流变化。 在两个定子之 间设置转子， 转子采用永磁磁钢或电磁线圈来产生磁场， 转子的内外两个
工作面均可切割磁力线， 就大大地提高了电机的功率密度， 缩小了电机的 体积。 另外， 当转子采用线圈通电产生磁场时， 这种磁场的大小可以通过 调节线圈的电流大小进行控制， 从而控制电机的效率最大化。 而将内极定 子绕组、 转子电磁线圈及外极定子绕组连接电机控制器， 就可以根据不同 的工作场合与工况， 通过电机控制器来控制电机的工作状态， 使电机适应 各种不同的工况， 大大地扩展了电机的使用范围。
作为优选， 转子架呈筒状结构， 筒状结构的两端通过内轴承可转动地 支承在内极定子的固定轴上， 转子的输出轴通过外轴承可转动地支承在电 机的前端盖上。 转子架是用来将设置有线圈的转子铁芯可转动地固定在内 外极定子之间的， 为了避免转子上的永磁磁钢或电磁线圈所产生磁场的影 响， 转子架通常采用非导磁结构的材料制作。
作为优选， 内极定子的固定轴后端设有电缆孔， 内极定子绕组的引出 线通过电缆孔穿出， 内极定子固定轴的后端固定在电机的后端盖上。 电机 工作时， 处于电机中心的固定轴是固定不转的， 因此可以在固定轴内设置 通孔， 使得内定子绕组或转子电磁线圈的引出线从通孔弓 I出。
作为优选， 内极定子的固定轴与内极定子绕组之间轴向设有通风道， 转子上设有风叶， 转子两端及电机的前后端盖上均设有通风孔， 电机的前 后端盖固定在电机的机壳上。 通风道、 风叶及通风孔的设置均是为了提高 电机的散热性能。
作为优选， 外极定子上设有传感器， 传感器检测转子的位置变化。 设 置传感器的目的是检测转子的位置变化， 以便电机控制器确定相应定子绕 组的相位， 使电机达到最佳工作状态， 传感器通常使用霍尔元件。
作为优选， 外极定子绕组与内极定子绕组的数量比为 3比 2或 2比 1。 考虑到外极定子的空间较大， 因此， 在外极定子上设置比内极定子数量更 多的绕组， 使外极定子绕组与转子组合后的功率大于内极定子绕组与转子 组合的功率， 这样， 电机在使用时， 可以有多种功率选择。
作为优选， 内极定子绕组通过内滑环装置连接电机控制器， 电磁线圈 通过外滑环装置连接电机控制器， 电机控制器内设有极性控制器， 外极定 子绕组连接极性控制器。 由于转子是转动的， 因此转子电磁线圈需通过滑 环装置连接电机控制器， 而内极定子绕组的极性变换可以通过滑环装置完 成， 也可以有电机控制器完成， 极性控制器根据传感器检测到的转子位置 来确定相应定子上的绕组极性， 使电机正常工作。 另外， 外极定子绕组的 极性变换则由电机控制器上的极性控制器完成。
作为上述二极电机的一种控制方法， 在转子采用永磁磁钢时， 电机上 的电机控制器根据电机的工作模式及负荷工况控制电机内定子绕组与外定 子绕组， 以达到控制电机工作状态的目的， 具体包括：
a.内极定子绕组供电， 电机输出轴输出转矩， 外极定子输出电流。 电 机的这种工作状态对应于电动机小负载的工况， 此时只需内极定子与转子 组合即可满足要求， 在系统减速或停止过程中， 还可以利用外极定子绕组 输出电流， 以充分利用系统的余能。
这种结构还可以用于电源转换， 在内极定子输入直流电的情况下， 同 过转子的作用， 外极定子上可以输出交流电流， 具有直流与交流转换的功 能， 在单一的电源转换模式下， 电机也可以不设置输出轴。
b.外极定子绕组供电， 电机输出轴输出转矩， 内极定子输出电流。 电
机的这种工作状态对应于电动机中等负载的工况， 此时需要外极定子与转 子组合来驱动电机， 和前面一样， 在系统减速或停止过程中， 也可以利用 内极定子绕组输出电流， 以充分利用系统的余能。
C.内极定子绕组与外极定子绕组同时供电， 电机输出轴输出转矩。 电 机的这种工作状态对应于电动机大负载的工况， 此时需要内极定子、 外极 定子与转子组合才能满足要求。
d.电机输出轴输入转矩， 内极定子绕组输出电流。 电机的这种工作状 态对应于发电机输入转矩较小的工况， 此时只需要内极定子绕组作为发电 机的输出。
e.电机输出轴输入转矩， 外极定子绕组输出电流。 电机的这种工作状 态对应于发电机输入转矩中等的工况， 此时需要外极定子绕组作为发电机 的输出。
f.电机输出轴输入转矩， 内外极定子绕组输出电流。 电机的这种工作 状态对应于发电机输入大转矩的工况， 此时需要内极定子绕组、 外极定子 绕组组合作为发电机的输出。
二极电机的另一种控制方法， 即当二极电机的转子采用电磁线圈通电 产生磁场的结构形式时， 电机上的电机控制器根据电机的工作模式及负荷 工况控制电机内定子绕组、 转子电磁线圈与外定子绕组， 以达到控制电机 工作状态的目的， 具体包括：
a.内极定子绕组与转子电磁线圈供电， 电机输出轴输出转矩， 外极定 子输出电流；
b.外极定子绕组与转子电磁线圈供电， 电机输出轴输出转矩， 内极定
子输出电流；
c.内极定子绕组、 转子电磁线圈与外极定子绕组同时供电， 电机输出 轴输出转矩；
d. 转子电磁线圈供电，电机输出轴输入转矩，内极定子绕组输出电流; e. 转子电磁线圈供电，电机输出轴输入转矩，外极定子绕组输出电流; f. 转子电磁线圈供电， 电机输出轴输入转矩， 内外极定子绕组输出电 流。
这种方法除转子电磁线圈需始终加电提供磁场外， 其他的工作原理与 前述控制方法相同， 另外， 转子电磁线圈的电流大小可以控制， 从而控制 电机达到最大的工作效率。
本发明的有益效果是： 它有效地解决了现有技术的电动机功率固定， 不适合负载变化较大的工作场合的问题， 还解决了现有发电机存在的输入 转矩变化较大时无法正常工作的问题， 本发明的电机体积小， 控制方便， 可以根据实际工况调整工作状态， 效率高， 既可作为电动机使用， 也可以 作为发电机使用， 节能效果明显， 具有显著的经济效益与社会效益。 附图说明
