We have been developed a novel spherical stepping motor (6-8 spherical stepping motor) which is based on a pair of a regular hexahedron and octahedron in order to make an application as a mechanical system such as a joint of a humanoid robot or an industrial robot. In this study, the rotational characteristics on the 6-8 spherical stepping motor were obtained by the 3D electromagnet and motion coupled simulation. As the result, the static torque characteristic, the frequency-velocity characteristic and torque characteristic around 3-axes were described.
