A double-stator motor of an example embodiment includes: an annular rotor connected to a rotary shaft and integrally rotates with the rotary shaft, an inner stator arranged radially inward of the rotor, and an outer stator arranged radially outward of the rotor. The rotor includes a plurality of segments annularly arranged in the circumferential direction, spaced apart from each other by a predetermined distance, and a plurality of permanent magnets each interposed between circumferentially adjacent segments, the permanent magnets being alternately magnetized in the circumferentially opposite direction. The rotor, the inner stator and the outer stator have the same number of poles. The inner and outer stator windings of the inner and outer stators, respectively, are connected so that their phases are reversed to each other. Thus, the magnetic fields generated by the magnetomotive forces of the inner and outer stators are applied to specific segments in parallel.
