摘要： A dynamoelectric machine including first and second permanent magnets held by first and second magnet seats on first and second yoke portions so as to face inner circumferential surfaces of tip end portions of first and second claw-shaped magnetic pole portions. The first and second permanent magnets are magnetically oriented in a reverse direction to orientation of a magnetic field that the field coil produces. The dynamoelectric machine enables permanent magnet holding reliability to be increased, induced voltage during no-load de-energization to be suppressed, and thermal demagnetization of magnets due to high-frequency magnetic fields that are induced by stator slots to be avoided.

摘要： A stator of a wire connection structure is capable of producing an unlimited number of non-integer turns. This stator is made by turning back first to sixth conductors on the outside of an end face of a stator iron core, and by mounting them in slots at a predetermined slot pitch in each of U, V and W phases. The sixth conductor is divided into two 0.5 turns coils. Connecting in parallel 1.5 turns of each coil, in which the second conductor and a first of the coils are connected, and 1.5 turns of a coil in which the fourth conductor and a second of the coils are connected, forms a 1.5 turns coil. Connecting in series the 1.5 turns coil, and 3 turns of a coil formed by connecting in series the first conductor, the third conductor, and the fifth conductor forms a 4.5 turns coil.
