ABSTRACT:
A portable gasoline generator, constructed with an engine and a generator, provides a lightweight and compact size for easy storage and carrying by minimizing its weight and size of the alternator (generator) thereof. The generator includes a generator case which houses a stator and a rotor unit that is coaxially coupled with a driving end of the crankshaft. The rotor unit includes a rotor cap and a plurality of arc-shaped rotor magnets made of rare-earth metal circularly attached to an inner circumferential surface of a surrounding ring of the rotor cap. The rotor cap is constructed to function as an exhausting fan by puncturing a plurality of fan wings aligned radially and forming a plurality of fan vents thereon. The stator is coaxially affixed to a generator cup of the generator case, wherein the stator is coaxially positioned within the rotor cap that the rotor magnets are arranged to coaxially surround the stator.
