摘要： A rotary electric machine includes a stator in which a plurality of armatures each have a coil formed by a winding wire wound in plural layers around bobbins mounted to a magnetic pole tooth, which are disposed annularly on an inner circumference of a cylindrical frame. The coil is formed by the winding wire being wound with a constant feed pitch in parallel with slots of the bobbins in plural layers. The winding wire forming a first layer of the coil is shifted by half the feed pitch between a left side and a right side of a center axis of the coil as viewed from a plane perpendicular to a stacking direction of a stacked iron core.

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.
