Abstract
A magnetic geared rotating machine, includes: a stator which includes a plurality of stator magnets arranged so as to be aligned in a circumferential direction; a rotor which includes a plurality of rotor magnets arranged so as to be aligned in the circumferential direction, and in which the number of magnetic poles of the plurality of rotor magnets is less than the number of magnetic poles of the plurality of stator magnets; and a magnetic pole piece rotor which includes a plurality of magnetic pole pieces arranged so as to be aligned in the circumferential direction. Each of the magnetic pole pieces has: a first face opposed to the rotor in a radial direction; and a second face opposed to the stator in the radial direction and having a circumferential length longer than a circumferential length of the first face.
