Abstract

The paper has presented a new structure of three-of-degree (3-DOF) permanent magnetic spherical motor (PMSM) including four layers of cylindrical rotor poles and two layers of coils without ferromagnetic core. The radial magnetic field influenced by magnetization direction and different structure of rotor poles are analyzed based on analytic method by toroidal function. With the torque model the effects on torque characteristic caused by the parameters of cylindrical poles, coil structure, core material and gap length are analyzed. The results provide reference for PMSM optimization.
