A control apparatus of an AC generator for a vehicle can obtain large regeneration energy without making the size of the generator large. In the control apparatus in which an AC output current is rectified and supplied to a vehicle mounted battery (6) and an electric load of the vehicle, provision is made for a regulator (5) that controls a continuity rate of electric power supply to a field coil (3) of a generator (1) by controlling an output voltage of the generator (1). The regulator (5) suppresses the continuity rate of electric power supply to the field coil (3) at the time of steady operation of the vehicle, and switches a suppression value of the continuity rate of electric power supply so as to increase the continuity rate of electric power supply at the time of deceleration operation of the vehicle.

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.

A stator winding is configured by connecting a first three-phase stator winding and a second three-phase stator winding in parallel. A U1-phase winding of the first three-phase stator winding is configured by connecting a U1-1-phase winding portion and a U1-2-phase winding portion in series, and a U2-phase winding of the second three-phase stator winding is configured by connecting a U2-1-phase winding portion and a U2-2-phase winding portion in series. The U1-1-phase winding portion and the U2-2-phase winding portion are m-turn wave windings, and the U2-1-phase winding portion and the U1-2-phase winding portion are n-turn wave windings (where n does not equal m). The U1-1-phase winding portion and the U2-1-phase winding portion are mounted into a first slot group, and the U1-2-phase winding portion and the U2-2-phase winding portion are mounted into a second slot group.

A method to manufacture an optical module is disclosed, wherein the optical module has an optically active device on a lead frame and a lens co-molded with the active device and the lead frame by a transparent resin as positioning the lens with respect to the lead frame. The molding die of the present invention has a positioning pin to support the lens during the molding. Because the lead frame is aligned with the molding die, the precise alignment between the active device on the lead frame and the lens is not spoiled during the molding.
