As a pioneering multi-DOF motor, the Integrated Magnetic Suspension Spherical Induction Motor (IMSSIM) presents many advantages. Nonetheless, the IMSSIM presents a complex magnetic coupling challenge. This paper addresses the magnetic coupling issue in IMSSIM through a comprehensive investigation using the 3-D finite element method (FEM). The magnetic coupling coefficients which reflect the magnetic coupling degree are proposed and analyzed. Moreover, the dynamic coupling effect inside the IMSSIM is analyzed and studied. Finally, accuracy of FEM is verified by prototype experiments.
