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 rotating electric machine includes coil bodies formed as a first stator winding wound on first teeth, other coil bodies formed as a second stator winding wound on second teeth, and yet other coil bodies formed as the first stator winding and the second stator winding wound on third teeth. A phase difference between an electric current in the first stator winding wound on the third teeth and an electric current in the second stator winding wound on the third teeth is set so that respective phase differences of magnetomotive forces of the other coil bodies in three phases with respect to respective magnetomotive forces of the coil bodies in three phases and respective phase differences of magnetomotive forces of the yet other coil bodies in three phases with respect to respective magnetomotive forces of the other coil bodies in three phases are 20 degrees in electric angle.

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.
