    • The system includes a continuous loop coil of flat, thin, rigid construction which levitates inside a quadrupole permanent magnet assembly with minimum gap. The linear coil may be a flat, racetrack-shaped, or continuous loop, which may be constructed with single or multilayers PCB, flex-circuit, or other membrane process. The linear coil may include a coating of magnetically permeable material along the insulated conductor traces. The linear coil may be sandwiched between carbon fiber fabrics and cured to create a long, flat, light-weight, load-bearing tee-shaped structure. This structure is levitated inside a quadrupole permanent magnetic assembly with an air gap between the magnets. In additional to the bare conductor traces inside this coil, also integrated into this PCB structure, is simple second order equalizer electronic circuitry. Either a close loop or open loop control may be included to tune the voltage amplitude at the resonance frequency of this magnetic drive system.
    • 该系统包括平坦,薄,刚性结构的连续环形线圈,其以最小间隙悬浮在四极永磁体组件内部。 线性线圈可以是平面的,跑道形的或连续的环,其可以用单层或多层PCB,柔性电路或其它膜工艺构造。 线性线圈可以包括沿着绝缘导体迹线的导磁材料的涂层。 线性线圈可以夹在碳纤维织物之间并被固化以产生长而平坦的重量轻的承重三通形结构。 这种结构悬浮在四极永磁组件内,磁体之间具有气隙。 除了这个线圈内部的裸导线之外,还集成在该PCB结构中,是简单的二阶均衡器电子电路。 可以包括闭环或开环控制以调谐该磁驱动系统的谐振频率处的电压幅度。
