摘要
Provided is a means for mitigating strict constraints between a virtual polyhedron inscribed in a rotor and a virtual polyhedron inscribed in a stator of a spherical stepping motor and a spherical AC servo motor and drastically increasing the degree of freedom in design. The above problem is solved by disposing permanent magnets at points of division of the sides of the virtual polyhedron inscribed in the rotor and electromagnets at points of division of the sides of the virtual polyhedron inscribed in the stator. A multiple pole spherical stepping motor and a multiple pole spherical AC servo motor include a rotor with permanent magnets disposed at the vertexes of a virtual polyhedron inscribed in a sphere and at points of division of arcs corresponding to the sides connecting the vertexes, and a stator with electromagnets disposed at the vertexes of a virtual polyhedron inscribed in a sphere containing the sphere of the rotor and at points of division of arcs corresponding to the sides connecting the vertexes.
