Abstract

A poly-generation system includes: at least one cylinder; a reciprocating piston provided in the cylinder; an engine rotor generates a magnetic force and reciprocates with the piston; an engine stator includes an engine coil which induces an electromotive force by interference with the reciprocating engine rotor and outputs the electromotive force induced in the engine coil; and a generator which is integrally coupled with a reciprocating shaft of the piston and generates electricity using an inertial force generated by the reciprocating piston, the generator includes: an elastic member deformed by the inertial force; a generator rotor includes a generator magnet and reciprocates due to the deformation of the elastic member; a generator stator includes a generator coil and outputs an electromotive force induced in the generator coil due to interference with the generator magnet, and a generator battery stores the electromotive force induced in the generator coil.
