  • APPARATUS, SYSTEM, AND METHOD FOR MULTI-STAGE HIGH GEAR RATIO HIGH TORQUE MAGNETIC GEAR
    Publication number: 20130320681
    Abstract: An apparatus, system, and method for multi-state high gear ratio magnetic gear are described. The magnetic gear may have a stationary shutter assembly with a bearing supporting bracket and a shutter supporting bracket extending perpendicularly from the bearing supporting bracket. The magnetic gear may also have an outer rotor assembly with an outer rotor magnetic assembly positioned circumferentially outside of the shutter supporting bracket. In addition, the magnetic gear may have an inner rotor assembly with an inner rotor magnetic assembly positioned circumferentially inside the shutter supporting bracket. In addition, a first bearing may couple the stationary shutter assembly to the inner rotor assembly and a second bearing may couple the inner rotor assembly and the outer rotor assembly.
