Abstract: A gas cooled electric rotating machine is provided in which a cooling gas is flowed through into a rotor and a stator. The rotor includes a pair of center hole conductors inserted into a center hole along a center of rotation while being electrically insulated from a shaft and from each other, the center hole conductors including respective protruding parts protruding toward an end of the shaft. The rotor includes a pair of end conductors provided at the end of the shaft so as to be each electrically insulated from the shaft, the end conductors being electrically connected to side surfaces of the protruding parts of the pair of center hole conductors, the side surfaces serving as electric connection surfaces.

Abstract: In one embodiment, a generator includes an alternating current exciter to output first, second and third alternating currents respectively having first, second and third phases, and a rotary rectifier to convert the first, second and third alternating currents into first, second and third direct currents, respectively. The generator further includes a rotating shaft on which the exciter and the rectifier are mounted, and plural conductors mounted on the shaft, and including one or more first conductors, one or more second conductors and one or more third conductors to respectively supply the first, second and third alternating currents from the exciter to the rectifier. The plural conductors include one or more conductor groups in each of which two or more conductors are collectively arranged, and each of the conductor groups includes the two or more conductors arranged to cancel a magnetic field around each conductor in the same group.
