This paper introduces a new spherical motion generator and presents a method for modeling its magnetic field and analyzing its moments. The generator employs an electromagnetic drive of a spherical motor as its driving method and utilizes a spherical parallel manipulator to execute the spherical motion. The combination of these two technologies offers several advantages, including a large workspace and high motion accuracy. The equivalent magnetizing current method is used in the magnetic field modeling and the average air-gap flux density is optimized to achieve a better magnetic field distribution, and the accuracy of the analytical model is verified by finite element simulations and experiments. • The electromagnetic-driven SMG merges the spherical parallel manipulator and motor. • A novel SMG is designed to provide large workspace and unlimited spinning motion. • Modeling the magnetic field of SMG as to optimize the magnetic pole arrangement. • The accuracy of the model is verified by finite element method and experiment.
