Patent ID: 6995477

Claim:
A multi-functional power source for producing an external mechanical power, comprising: a generator for outputting induced electric power, comprising: a generator housing having a receiving chamber; a rotor comprising a magnetic element which is coaxially and rotatably disposed within said receiving chamber and defines a magnetic cavity therein, and a stator comprising a coil assembly coaxially disposed within said magnetic cavity; and an engine arrangement, comprising: an internal combustion engine; a crankshaft having an driven portion extended from said internal combustion engine and a driving portion coupled with said rotor in such a manner that, when said internal combustion engine produces a mechanical power to drive said rotor to rotate through said crankshaft, said magnetic element is rotated to induce with said coil assembly for producing said induced electric power; and an output axle extended from said crankshaft to a position out of said generator housing, wherein when said crankshaft drives said output axle to rotate, said output axle is adapted for producing said external mechanical power, wherein said output axle is integrally extended from said crankshaft and has an output end being driven to rotate for producing said external mechanical power even when said generator is producing said induced electric power, wherein said output axle is integrally and coaxially extended from said driving portion of said crankshaft while said output end of said output axle is coaxially extended through said magnetic cavity to an exterior of said generator housing, wherein said engine assembly further comprises a second output axle, having a second output end, integrally and coaxially extended from said driven portion of said crankshaft while said second output end of said second output axle is coaxially extended to an exterior of said engine casing at a direction opposite to said output end of said output axle, wherein said coil assembly comprises a plurality of wire coils radially positioned within said magnetic cavity of the magnetic element to form a coil disc, having a central stator hole, securely supported within said magnetic cavity, wherein said output axle is coaxially extended through said central stator hole to said exterior of said generator housing.
