PROBLEM TO BE SOLVED: To provide a motor in which a plurality of rotors can be synchronously rotated by comparatively simple constitution and control. SOLUTION: This motor is equipped with a housing 2, first to third rotors 4, 6, 8 which are rotatably retained at intervals in the housing 2, a first stator 32 arranged on one sides of the first and second rotors 4, 6, a first magnetic member 40a arranged on the other sides of the rotors 4, 6, a second magnetic member 40b arranged on one sides of the second and third rotors 6, 8, and a second stator 34 arranged on the other sides of the rotors 6, 8. The first to third rotors 4, 6, 8 have annular rotor magnets 20a, 20b, 20c wherein N poles and S poles are alternately arranged at practically equal intervals in the circumferential direction. The rotor magnets 20a, 20b, 20c have the same number of magnetic poles.
