Transmission Torque Analysis of a Novel Magnetic Planetary Gear Employing 3-D FEM

This paper describes the transmission torque characteristics of a novel magnetic planetary gear. A hybrid-type magnetic planetary gear is proposed, and the operational principle is shown when it is operated as a star-, planetary-, and solar-type magnetic planetary gear. The dynamic transmission torque characteristics are computed by employing 3-D finite-element method, and lastly verified by carrying out measurements on a prototype.
