When a robot system is developed by normal motors that rotate around one axis, the necessary number of motors is the same as that of joints resulting in a large and complicated system. On the other hand, spherical motors will realize a small and simple mechanism because they can rotate in various direction. A group of spherical motors that can rotate in 360 degrees is proposed by applying the working principle of planer stepping motor to spherical motors. There are various types in arranging permanent magnets on the rotor and electro-magnets on the stator. This study utilizes the arrangement in which a permanent magnet is placed on the apex of a truncated octahedron for the rotor and on electro-magnet is placed on either the apex of a regular dodecahedron or the middle point of two apexes for the stator. This study develops a spherical motor that can rotate around six axes and demonstrates the rotation around their axes.
