摘要： A multi-freedom electric motor has a broad operational range and a wide space for accommodating an article. The electric motor includes a spherical rotor, a plurality of magnets disposed on an outer surface of the rotor with polarities of the respective adjacent magnetic poles being different from one another, a stator provided along the outer surface of the rotor, and a plurality of magnets opposed to the magnets disposed on an inner surface of the stator. The rotor is supported by a spherical bearing provided on the stator. Either the magnets on the rotor or the magnets on the stator are electromagnets. Electric current are supplied to the electromagnets as controlled by a controller. The multi-freedom electric motor can be employed in a space stabilizer for maintaining the spherical attitude of an article, a control moment gyro for performing an attitude control in space, and an agitating apparatus.
