摘要： A low loss synchronous magnetic drive system for high pressure, high horsepower applications is disclosed. A carrier member (24) driven by a drive motor carries spaced apart sets of drive magnets (46, 48) with the magnets of one set being of opposite polarity to the longitudinally aligned magnets of the other set. An output shaft (28) carrying driven magnets (50, 52) oriented similarly to the drive magnets is also provided. A metallic hyperbaric barrier (54) separates the drive and driven magnets. The barrier includes an outer cylinder (56) having circumferentially spaced, radially directed, narrow slots (70) extending therealong. Within the cylinder is a plurality of axially adjacent annular laminations (78) insulated from each other. During operation the combination of the slotted cylinder, the laminations and the magnet arrangement keeps eddy currents generated in the barrier at a minimum, ensuring a high efficiency drive operable at speeds and pressures heretofore unattainable.

摘要翻译：公开了一种用于高压，高功率应用的低损耗同步磁驱动系统。由驱动马达驱动的载体构件（24）承载间隔开的一组驱动磁体（46,48），其中一组的磁体与另一组的纵向对准的磁体具有相反的极性。还提供了一个承载与驱动磁体类似的驱动磁体（50,52）的输出轴（28）。金属高压屏障（54）将驱动和驱动磁体分开。阻挡层包括具有沿其周向延伸的径向指向的窄槽（70）的外筒（56）。圆柱体内是彼此绝缘的多个轴向相邻的环形叠片（78）。在操作期间，开槽圆柱体，叠片和磁体布置的组合将在屏障中产生的涡流保持在最小，确保高效率的驱动器可以在迄今无法实现的速度和压力下操作。
