Abstract: A 3-freedom degree of a spherical wheel motor is provided to reduce an eddy current by suppressing temporal variation of magnetic flux by a rotor and to simplify an entire structure by burying a coil in a stator core. A 3-freedom degree of a spherical wheel motor(100) includes a double gap(60), a back yoke(12), and a buried coil(40). The double gap is formed between a nonmagnetic stator(30) and a rotor(10). The back yoke rotates with a magnetic pole of the rotor. The buried coil is configured by burying a coil for forming an electrical magnetic pole in the nonmagnetic stator. A spherical bearing(50) for generating restoration force is provided in a center portion of the spherical wheel motor so that the rotor is positioned in the center of the nonmagnetic stator.
