Abstract
A rotor is fitted on a rotational driving shaft of an internal combustion engine. Permanent magnets are arranged on the circumference of the rotor. Opposing the permanent magnets, a number of coils for charging a battery used for lighting, and a group of coils for charging a condenser used for ignition, are arranged on the stator core radially. The group of coils for charging the condenser are arranged on a number of salient poles extending along the axial direction of the stator. The coils for charging the ignition condenser generate two separate voltages at low and high rotational speeds of the engine.
