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.
