摘要： 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.

摘要： According to one embodiment, there is provided a 3-phase 4-pole 2-layer armature winding of a rotating electrical machine. A winding of each phase of the armature winding forms a series coil. Each series coil includes upper coil pieces and lower coil pieces which are connected each other at a connection side coil end and a counter-connection side coil end, the upper coil pieces and lower coil pieces being placed in 42 slots provided in an armature core. At least one coil piece of the upper and lower coil pieces, provided in at least one of an innermost position and an outermost position from the center of a phase belt of each phase, is replaced with a coil piece of an adjacent phase.
