PROBLEM TO BE SOLVED: To reduce torque ripple during the energization of a rotary motor, and to suppress vibrations and the like.SOLUTION: A rotary motor 1 comprises a plurality of rotors 11 having the same structures and equipped with permanent magnets 12 and 13, and a plurality of stators 10 equipped with coils 14. The plurality of rotors 11 is adjacently disposed so as to synchronously rotate in the same rotating direction on the same rotation axis, or adjacently disposed so as to synchronously rotate in the same rotating direction on rotation axes in parallel with each other. The permanent magnets 12 and 13 are installed to each rotor 11 so as to have phase difference in the rotating direction between the adjacent rotors. Each slot 16 or each teeth portion 15 of the stator disposed at a position corresponding to each rotor 11 are equipped with a coil 14 of a plurality of phases so as to have current phase difference in the rotating direction between the adjacent stators. |
