    • An electric motor 1 includes a first structure 4 including a magnetic pole row formed by a predetermined plurality of magnetic poles 4a arranged in a predetermined direction, a second structure 3 including an armature row disposed in a manner opposed to the magnetic pole row, for generating moving magnetic fields moving in the predetermined direction between the armature row and the magnetic pole row, and a third structure 5 including a soft magnetic material element row. The third structure disposed such that the soft magnetic material element row is positioned between the magnetic pole row and the armature row. A ratio between the number of the armature magnetic poles, the number of the magnetic poles 4a, and the number of the soft magnetic material elements 5a is set to 1:m:(1+m)/2 (m≠1.0).

    • [Object] To provide an electric motor which is capable of enhancing the efficiency thereof. [Solution] An electric motor 1 includes a plurality of first electromagnets 4a, armatures 5a, second electromagnets 6a, first cores 7a, and second cores 8a, which respectively have a plurality of first electromagnets 4a, armatures 5a, second electromagnets 6a, first cores 7a, and second cores 8a. When the polarity of the first armature magnetic pole of each armature 5a is different from that of a first magnetic pole of a first electromagnet 4a opposed thereto, the polarity of each second armature magnetic pole of the armature 5a is the same as the polarity of a second magnetic pole of a second electromagnet 6a. Further, when the first core 7a is positioned between the first magnetic pole and the first armature magnetic, the second core 8a is positioned between circumferentially adjacent two pairs of second armature magnetic poles and second magnetic poles.
