The linear coil may be a flat, racetrack-shaped, 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 permeable magnetic material along the insulated conductor traces. The linear coil may be sandwiched between carbon fiber fabrics and cured to create a long, flat, thin and perfectly straight, extremely stiff, light-weight, load-bearing tee-shaped structure. This structure is levitated inside a quadrupole permanent magnetic assembly with minimum air gap between the high gauss magnets. In additional to the bare conductor traces inside this coil, also integrated into this PCB structure, is simple second-order equalizer electronic circuitry, comprised of surface-mounted resistors, capacitors, and IC chips. 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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Moving coil module comprising a substrate patterned with a conductor trace","description":"A linear moving coil magnetic drive system includes a continuous loop coil of flat, thin, rigid construction which levitates inside a quadrupole permanent magnet assembly with minimum gap.
