  • Abstract
    A magnetic gear offers many advantages over its mechanical counterpart such as contact free torque production, no gear lubrication and inherent overload protection. However, current magnetic gear designs use large quantities of rare- earth magnet material and unfortunately the high cost of rare-earth material makes the magnetic gear uncompetitive with alternative technology. This paper investigates a low-cost magnetic gear using ferrite magnets.
