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： An automotive dynamoelectric machine that achieves disposing of permanent magnets and thickening of field coil wire by disposing trough portions on yoke portions and disposing magnet holders that hold the permanent magnets so as to span the trough portions to ensure outlet space for field coil lead wires. In the dynamoelectric machine, trough portions are formed on respective portions of yoke portions between circumferentially adjacent claw-shaped magnetic pole portions, a magnet holder is disposed so as to span over a trough portion, and a permanent magnet is held by the magnet holder. A lead wire is led out of a rotor from a field coil so as to pass through a space that is bounded by the trough portion and the magnet holder.

摘要： A dynamoelectric machine that can suppress increases in rotor inertia to extend belt service life and increase field magnetomotive force to increase output. In the dynamoelectric machine, first and second magnetic guidance members are fitted into first and second holding grooves that are disposed so as to extend axially on facing portions of first and second trough portions radially outside inner wall surfaces, and are disposed so as to span over first and second trough portions. First and second permanent magnets that are magnetically oriented in a reverse direction to a magnetic field that originates from a field coil are fitted into and held by interfitting grooves of the first and second magnetic guidance members so as to face inner circumferential surfaces near tip ends of second and first claw-shaped magnetic pole portions so as to have a predetermined clearance.
