ENGINE GENERATOR

摘要

An engine generator, wherein, in a recessed part (4a) of a flywheel (4) of an engine (E), rotor magnets (6) comprising ferromagnetic permanent magnets are installed fixedly on the inner peripheral surface of the flywheel (4) and stator coils (7a) as armature poles which are installed on a stator (7) installed fixedly to an engine proper (1) through a stator bracket (8) and set so that they can output a high frequency power are allowed to face the rotor magnets (6) so as to form a generator (D) in the recessed part (4a), a blowing vane (5a) is installed on the outside of the flywheel (4) so as to form a cooling fan (5) and, in the flywheel (4), ventilating holes (4c) for communication of the installation space for the cooling fan (5) with the recessed part (4a) are formed so that cooling air is blown from engine cooling air passages (1e, 1g) formed in the engine proper (1) to the cooling fan (5) through the generator (D) formed in the recessed part (4a) and the ventilating holes (4c).
