Abstract
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.
