<p>A multi-freedom electric motor having a broad operation range of a rotor and including a wide space for accommodating a loaded article within the rotor, is realized. In the proposed electric motor, a plurality of magnets are disposed on an outer surface of a rotor of true spherical shape so that the polarities of the respective adjacent magnetic poles may differ from one another, a stator having a plurality of magnets opposed to the above-mentioned magnets disposed on its inner surface side is provided along the outer surface of the above-mentioned rotor, the rotor is supported by means of a spherical bearing provided on the stator, either the magnets on the rotor or the magnets on the stator are electromagnets, and electric currents flowing through the electromagnets are controlled by a controller. Also, by making use of the proposed multi-freedom electric motor, a space stabilizer for maintaining an attitude of an article so as to be directed spatially in a given direction, which is simple in structure and small in size, a control moment gyro for performing an attitude control in an arbitrary space, and an efficient agitating apparatus making use of the multi-freedom rotation, can be provided.</p> |
