Calculation of Air Gap Magnetic Field and Torque of Dual-modulation Axial Magnet Gear Motors

Jixie chuandong
A dual-modulation axial magnet gear motor （DAMGM） was proposed to address the shortcomings of the axial magnet gear motor （AMGM）, which has a large overall size and low torque density（≤70 kN·m/m3）.

An analytical fast field solver for surface permanent magnet co‐axial magnetic gears

IET Electric Power Applications
Abstract A mathematical model of co‐axial magnetic gears is given for the prediction of magnetic field distribution and the magnetic forces. The modelling approach is based on the separation of variables method (SVM), Sturm–Liouville problem, and spectral analysis.

An Investigation into the Torque Capabilities of High Gear Ratio Magnetic Gearboxes

, 2018
Mechanical gears can be as small as those in traditional mechanical watches or as large as those in mechanical marine turbines. They can be seen in almost all transportation tools, for example, bicycles, cars, trains and airplanes.
