    • Embodiments of the present invention include a shaft-less energy storage flywheel system. The shaft-less energy storage flywheel system includes a solid cylindrical flywheel having permanent motor magnets mounted about the flywheel. The shaft-less energy storage flywheel system also includes a motor stator having motor windings carrying electrical currents. The motor windings of the motor stator are aligned with the permanent motor magnets of the flywheel such that rotation of the flywheel is induced through interaction of the motor winding currents and the magnetic field of the permanent motor magnets. The flywheel provides a magnetic flux path for the permanent motor magnets. In certain embodiments, the shaft-less energy storage flywheel system includes a magnetic bearing assembly disposed directly adjacent an axial face of the flywheel. The magnetic bearing assembly controls positioning and alignment of the flywheel without physically contacting the flywheel during normal operation.
    • 本发明的实施例包括无轴无能量储能飞轮系统。 无轴无节能飞轮系统包括固体圆柱形飞轮,其具有围绕飞轮安装的永久电机磁体。 无轴式储能飞轮系统还包括具有承载电流的电动机绕组的电动机定子。 电动机定子的电动机绕组与飞轮的永久电动机磁体对准,使得通过电动机绕组电流和永久电动机磁体的磁场的相互作用来引起飞轮的旋转。 飞轮为永磁电机磁铁提供磁通路径。 在某些实施例中,无轴无功储能飞轮系统包括直接邻近飞轮的轴向面设置的磁轴承组件。 磁性轴承组件控制飞轮的定位和对准,而不会在正常运行期间物理接触飞轮。
