Abstract: A power transmission apparatus working to magnetically transmit power is provided which includes a first rotor including n soft-magnetic members, a second rotor including k soft-magnetic members, and a third rotor including magnets whose number of pole pairs is m where m is an integer more than or equal to one, the number of the magnets meeting a relation of 2m=|k±n| where n and k are an integer more than one. The first rotor, the second rotor, and the third rotor are arranged in magnetic coupling with each other. The soft-magnetic members of each of the first rotor and the second rotor are arranged at intervals away from each other, thereby minimizing the leakage of magnetic flux flowing from one of the soft-magnetic members to another in each of the first and second rotor to ensure the stability in operation of the power transmission mechanism.

Abstract: An electric rotating machine includes a power transmission mechanism and an armature. The power transmission mechanism is equipped with a first, a second, and a third rotor. The first rotor includes n soft-magnetic members. The second rotor includes k soft-magnetic members. Note that n and k are an integer more than one. The third rotor is made up of magnets whose number of pole pairs is m where m is an integer more than or equal to one. The armature faces the third rotor. The first, second, and third rotors are arranged so as to establish a magnetic coupling among them. The soft-magnetic members of the first and second rotors and the magnets of the third rotor meet a relation of 2m=|k±n|. This arrangement is capable of achieving the transmission of power regardless of electric energization of the armature.

Abstract: A magnetic modulation motor includes an armature, a magnetic induction rotor, and a magnet rotor. The armature is provided with a multi-phase winding with m pole pairs. The magnetic induction rotor includes k magnetic paths. In the magnet rotor, 2n permanent magnets forming a polarity region with n pole pairs are separately and annularly placed. The armature, the magnet rotor, and the magnetic induction rotor are arranged in the order from a radially outer side to a radially inner side. In the magnetic induction rotor, the magnetic path has two ends projecting toward a magnetic flux entry and exit located at an outer diameter face of the magnetic induction rotor, and forms a magnetic flux path between the magnetic flux entry and exit. The magnet rotor includes magnetic flux penetration region magnetically penetrated by magnetic flux between each circumferentially adjacent two permanent magnets.
