Halbach Cladding Magnets for Friction Reduction in Magnetic Gears
TS-065418 — Traditional mechanical gears rely on physical teeth engagement to transfer motion and torque while magnetic gears use the repulsive or attractive forces between magnets to achieve the same goal. Magnetic gears have several advantages: low noise and vibration, reduced maintenance, and inherent overload protection. Magnetic gears are used in applications that require variable speed control and precise torque transmission, such as robotics, aircraft, and automation.
Although magnetic gears provide several advantages to their traditional mechanical counterparts, they suffer from torque transmission inefficiency due to end-effect loss, which occurs when the magnetic flux leaks axially into the surrounding air and fails to couple between the rotors. As industri…

Halbach Cladding Magnets for Reduced End-Effect Losses in Magnetic Gears
TS-054666 — Implementation of Halbach array cladding magnets to focus magnetic flux to improve specific torque output of magnetic gearing systems.
Magnetic gears exploit modulation of rotor magnetic field harmonics to perform gearing operations with only bearing contact between the parts of non-zero relative velocity. A magnetic outer rotor, magnetic inner rotor, and flux modulator operate in concert to either decrease or increase the speed …
