N2 - This paper presents modeling of an integrated design of an electromagnetic driven spherical motion generator with multi-layer structure. An analytical method to calculate the complex magnetic field distribution of the rotor array by combining the equivalent charge model and transformation method is developed, upon which torque model is further established analytically by using the moment principle. Both the analytical magnetic model and torque model are validated with the numerical finite element method by Ansoft Maxwell and experimental measurements. With the model, two different designs of the electromagnetic driven SMGs are analyzed to illustrate the application of the developed model.
