Description

双转子结构电机装置 所属领域
本发明涉及一种电机装置， 特别是一种电机双转子结构装置。 背景技术
异步电动机、 同步交流电动机、 同步交流发电机、 直流无刷电动 机， 都是采用单一转子结构， 定子是磁性材料。 异步电动机在转子 上加装转子线圈， 由于定转子之间存在转差、 转子线圈产生感应电 动势， 并形成转子磁场磁动势， 转子磁场磁动势对磁性材料定子产 生磁制动转矩。 同步交流电动机、 同步交流发电机、 直流无刷电动 机， 在转子上加装永磁材料或装有电励磁线圈， 建立磁极， 并形成 恒定磁场， 转子形成的恒定磁场对磁性材料的定子产生磁制动转矩。 由于要克服以上电机产生的这种磁制动转矩， 使电机增加了能量消 耗， 同时也减少了输出功率。 发明内容
本发明的目的是提供一种起动耗能小、起动负载大、空载损耗小、 输出功率大， 节约能源的电机双转子结构装置。 本发明的目的是通 过以下结构实现的：本发明为一种电机双转子结构装置， 主轴上固定 安装着转子： 机壳内安装着双转子结构，两个转子分别安装固定在旋 转轴上， 双转子轴位于同一个轴心线上， 双转子分别置于定子的两 侧，双转子的对应面上固定着含磁体， 定子安装固定在机壳上。定子、 定子轭采用非磁性材料。 本发明的双转子之间在磁场的作用下， 形 成同一磁场， 分轴装置的双转子在同一磁场的牵制下同步运转， 由 于在双转子中间定子、 定子轭的材质是非磁性的， 转子磁场与定子 之间不存在磁制动转矩， 电动机定子线圈产生的旋转磁场直接带动 转子磁场， 进而带动双转子随定子线圈产生的旋转磁场运行， 发电 机上双转子磁极间产生的恒定磁场由外动力直接推动旋转、 切割定 子线圈发电。 由于采用本发明电机双转子结构装置， 电机不存在转 子磁场对定子产生的磁制动转矩， 电机也就不存在为克服转子磁场 对定子产生的磁制动转矩上的能量消耗， 从而使电机起动能耗减小， 起动负载增大， 空载损耗减小， 输出功率增大。 因此本发明可以起 到节能增效的技术效果。 本发明转子上的含磁体， 根据电机种类相 应采用： 转子线圈、 永磁体、 电励磁线圏， 分单转子装配和双转子 装配。 本发明可以适用于异步交流电动机、 同步交流电动机、 直流 无刷电动机， 同时还适用于同步交流发电机， 可广泛推广使用。 附图说明
