Abstract: A generator includes a housing; a rotational shaft at least partially inserted into the housing; a rotor coupled to the rotational shaft and rotated together when the rotational shaft is rotated; a stator positioned between an inner surface of the housing and an outer surface of the rotor; a cooling module including a fan cover coupled to the housing, and a fan installed inside of the fan cover to generate a flow of an air passing through an inside of the housing; and a rotation support part including a cylindrical bearing holder positioned inside of the housing, and a bearing which is coupled to an inner circumferential surface of the bearing holder and rotatably supports the rotational shaft, the bearing holder forming a flow path of the air blown by the fan in at least one of an inner side or an outer side.

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.

Abstract: A generator according to the present disclosure includes: a housing forming an outer shape; a rotation shaft that is at least partially inserted into the housing, and rotated according to external power; a rotor coupled to the rotation shaft and rotated together when the rotation shaft is rotated; a stator that is positioned between an inner surface of the housing and an outer surface of the rotor, and wound around with a coil; a cooling module including a fan cover coupled to the housing, and a fan installed inside the fan cover to cause a flow of an air passing through the inside of the housing when a certain power is supplied; and a rotation support part including a cylindrical bearing holder positioned inside the housing, and a bearing which is coupled to an inner circumferential surface of the bearing holder and rotatably supports the rotation shaft. In this case, the bearing holder may effectively remove heat generated in the bearing by forming a flow path of the air flowing by the fan in at least one of an inner side and an outer side.
