Abstract: Provided is a generator that converts mechanical energy transmitted through a rotation shaft perpendicularly coupled to a flywheel as an output shaft of an engine into electrical energy. The generator includes: a rotor coupled to the rotation shaft and rotated together when the rotation shaft is rotated; and a stator which has an inner surface positioned adjacent to an outer surface of the rotor and is wound around with a coil, wherein the engine includes: a plurality of blades installed in a side surface of the flywheel facing the rotor and rotated together with the flywheel when the rotation shaft is rotated; and an engine bracket which has a through hole through which the rotation shaft passes, has one side that is opened to accommodate the flywheel therein, and is coupled to the stator, wherein the engine bracket forms an air flow path for guiding air flowed into the flywheel through an inside of the rotor to the stator, when the plurality of blades are rotated.
