ABSTRACT:
A rotary electric motor is provided which comprises an annular first rotor, an annular stator disposed concentric with and radially outside the first rotor, and an annular second rotor disposed concentric with and radially outside the stator, the stator including a stator core made up of a plurality of stator pieces that are arranged in a circular array and electrically independently from each other, coils wound around the respective stator pieces, annular first and second brackets disposed on opposite axial ends of the stator core, a fastening device passing through holes of the first and second brackets and fixedly holding the stator core between the first and second brackets, and an induction current suppressing device suppressing an induction current that is produced in response to a variation of magnetic flux of each of the coils and flows through the fastening device.
