Multiple pole spherical stepping motor and multiple pole spherical AC servo motor

A multiple pole spherical stepping motor comprising:

• a rotor with N-pole and S-pole permanent magnets disposed alternately and adjacent to one another at vertexes of a virtual regular tetrahedron inscribed in a sphere and at points dividing arcs corresponding to sides connecting the vertexes into an even number of equal parts;
• and
• a stator with electromagnets disposed at vertexes of a virtual regular tetrahedron inscribed in a sphere containing the sphere of the rotor and at points dividing arcs corresponding to sides connecting the vertexes into an odd number of equal parts.
