Abstract:
A method for designing an optimal bi-axial type of magnetic gears system, comprising the steps of:(a) providing a non-coaxial magnetic gears system including at least two magnetic gears having a hard magnetic material;(b) setting a distance between the magnetic gears and a ratio of an external ring radius of the magnetic gear over a thickness of the hard magnetic material layer of the magnetic gears;(c) finding a peak value of a torque versus a number of magnetized pole curve for the hard magnetic material used;(d) optimizing the magnetic gears system to obtain an optimal torque by magnetizing an optimal number of magnetic poles on the magnetic gears; and(e) varying the distance between the magnetic gears and the ratio of the external ring radius over the thickness of the hard magnetic material layer separately, and then repeating the procedures as described in steps (c) to (e).
