Proposal of a truncatedoctahedron-dodecahedron based spherical stepping motor

A novel stepping motor principle based on a pair of truncatedoctahedron and dodecahedron is proposed. At first, the advantages of the spherical motor are presented. Then, the goal of the spherical motor project is shown. Next, the principle of the conventional stepping motor is reviewed. Then, expand the principle of the conventional stepping motor to the three dimensional space with an example of a truncatedoctahedron and a regular dodecahedron based spherical stepping motor. Some polyhedrons are introduced for the candidates of making another polyhedron based spherical stepping motors. The proposed spherical stepping motors will be wide working area and high-torque.
