    • A rare earth permanent magnet coreless generator set is provided, comprising: a frame, an engine, a generator, an inverter and an output power box, wherein the generator further comprises: a generator holder mounted on the engine; a generator casing mounted on the generator holder; a stator mounted on the generator casing, comprising disc windings and a shell made of polymer covering the disc windings; a first magnetism stopper mounted on an output shaft by a flat key; a second magnetism stopper mounted on the output shaft by the flat key; a plurality of rare earth permanent magnets mounted on the first magnetism stopper and the second magnetism stopper by a permanent magnet clamp and corresponding to the stator. The rare earth permanent magnet coreless generator set generates less heat and has higher power output efficiency.
    • 提供了一种稀土永磁无芯发电机组,包括:框架,发动机,发电机,逆变器和输出电力箱,其中发电机还包括:安装在发动机上的发电机保持架; 安装在发电机支架上的发电机壳体; 安装在发电机壳体上的定子包括盘绕组和由聚合物制成的壳体,覆盖盘绕组; 通过平键安装在输出轴上的第一磁力塞; 通过平键安装在输出轴上的第二磁力塞; 多个稀土永磁体,其通过永磁体夹具安装在第一磁性止动器和第二磁性止动器上,并对应于定子。 稀土永磁无芯发电机组产生的热量较少,功率输出效率更高。
