CLADDING MAGNET APPLICATION TO CYCLOIDAL MAGNETIC GEARS

Abstract: an improved magnetic gear is provided that mitigates end-effect loss in cycloidal magnetic gears by adding axially magnetized cladding magnets to the ends of the magnet rotors that redirect the escaping magnetic flux back into the magnetic circuit. the most influential design factors defining the cladding magnet are identified as the height and depth ratio (ratios of dimensions in radial and axial directions, respectively) and the magnetization orientation or tilt of the cladding magnets. the ideal height ratio is found to be approximately 50-60%, while the optimal tilt is around 15 degrees for the cycloidal configuration.
