摘要： A method of forming a liquid-forged article. The method comprises introducing a melt into a die cavity; moving a punch relative to the die cavity such that the melt enters at least one high aspect ratio cavity in the punch and air is released via at least one air vent insert in the punch; and exerting a forming pressure on the melt while the melt solidifies in the high aspect ratio cavity.

摘要： A rotor assembly for use in an electric motor or generator where the mass of the rotor assembly is reduced with respect to conventional rotor assemblies. In addition, the rotor assembly is configured to be scalable to different sized electric motors. Within the rotor assembly, the rotor hub, the shaft, and the permanent magnets can independently or collectively be modified to have a reduced mass. In one aspect, a portion of the rotor hub adjacent to the shaft is configured with passages and spokes. In another aspect, an intermediate hub with lightening holes is provided between the shaft and the rotor hub. In yet another aspect, a large diameter hollow shaft replaces a portion of the rotor hub. In yet another aspect, the permanent magnets are configured to have an arc-shape, which permits the thickness of the magnets to be reduced without reducing the efficiency of the magnets.
摘要翻译：一种用于电动机或发电机的转子组件，其中转子组件的质量相对于常规转子组件减小。此外，转子组件被配置为可扩展到不同尺寸的电动机。在转子组件内，转子轮毂，轴和永磁体可独立或共同地被修改为具有减小的质量。在一个方面，与轴相邻的转子毂的一部分配置有通道和辐条。在另一方面，在轴和转子毂之间设置有带减光孔的中间轮毂。在另一方面，大直径空心轴代替转子毂的一部分。另一方面，永久磁铁构造成具有弧形，这允许减小磁体的厚度而不降低磁体的效率。
