摘要： A positive-side heatsink and a negative-side heatsink that constitute a rectifier are disposed inside a case at a rear end of a rotor so as to be separated axially such that front surfaces of a positive-side base portion and a negative-side base portion face each other. The negative-side heatsink is disposed such that radiating fins that are disposed so as to project from a rear surface of the negative-side base portion are positioned radially outside a cooling fan so as to face a coil end of a stator coil.

摘要： An automotive dynamoelectric machine that achieves disposing of permanent magnets and thickening of field coil wire by ensuring outlet space for field coil lead wires. In the dynamoelectric machine, trough portions are formed on portions of yoke portions between respective circumferentially adjacent claw-shaped magnetic pole portions. Magnet holders are disposed so as to span over all of the trough portions on a pole core body at a rear end excluding a predetermined trough portion, and permanent magnets are held in each of the magnet holders. A field coil lead wire is led out from the rotor so as to pass through the trough portion over which a magnet holder is not disposed.
