Abstract: Embodiments of the invention provide a method, device, and turbopump configured to suppress higher order cavitations at an inducer tip in a turbopump. An inducer having a tip is rotated, and a first flow is induced axially through the inducer at a first velocity. A second fluid flow is introduced toward a tip of the inducer substantially parallel to the first fluid flow at a second velocity that is greater than the first velocity, such that back flow through the tip of the inducer is reduced.

Abstract: The present invention discloses small compact motor systems which may be located inside a vehicle drive wheel, and which allow a drive motor to provide the necessary torque with reasonable system mass. The motor systems of the invention utilize polyphase electric motors, and are preferably connected to appropriate drive systems via mesh connections, to provide variable V/Hz ratios. In one embodiment the stator coils are wound around the inside and outside of the stator. In a further embodiment, the machine contains a high number of phases, greater than three. In a further embodiment, the phases are connected in a mesh connection. In a further embodiment, each half-phase is independently driven to enable second harmonic drive for an impedance effect. Improvements are apparent in efficiency and packing density.
Abstract translation: 本发明公开了一种小型紧凑型电动机系统，其可以位于车辆驱动轮内部，并且允许驱动电动机以合理的系统质量提供必要的扭矩。 本发明的电机系统利用多相电动机，并且优选地通过网状连接连接到适当的驱动系统，以提供可变的V / Hz比。 在一个实施例中，定子线圈缠绕在定子的内部和外部。 在另一个实施例中，机器包含大于3的大量相。 在另一实施例中，这些相以网状连接方式连接。 在另一个实施例中，每个半相被独立地驱动以实现阻抗效应的二次谐波驱动。 改进效率和包装密度是显而易见的。
