Analysis of Some Design Parameters and Constructive Solutions for Coaxial Magnetic Gears

This paper presents the torque focused design optimization and analysis of coaxial magnetic gears parameters when implementing some constructive and assembly solutions.

A theoretical investigation of several proposed solutions for mounting the permanent magnets on the surfaces of inner and outer rotors is held. The mounting of magnetic pieces on outer and inner rotors is considered as the benchmark models of magnetic gears do not display the actual torque capability provided by their constructed versions.

Design, geometry, and assembly of magnetic flux modulator are studied to determine some feasible solutions.

The impact of above-mentioned parameters on the torque capability are then studied and calculated with the help of finite element method (FEA) and the results are summarized and presented.
