<p><P>PROBLEM TO BE SOLVED: To provide an electric motor capable of enhancing efficiency. <P>SOLUTION: An electric motor 1 includes a plurality of first magnets 4a each aligning circumferentially, an armature 5a, a second magnet 6a, first to third stators 4 to 6 having a first core 7a and a second core 8a respectively, a first rotor 7 and a second rotor 8. When the polarity of a first armature pole of the armature 5a is different from the polarity of a first pole of opposing first magnets 4a thereto, the polarity of a second armature pole of the armature 5a becomes the same as the polarity of second pole of the opposing second magnet 6a thereto. Also, when the first core 7a is located between the first pole and the first armature pole, the second core 8a is located between the second armature pole and the second pole adjoining circumferentially to each other. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
