Abstract:
1. A combined generator with built-in eddy-current magnetic resistance, comprising: a) an outward turning type inertia flywheel having an external ring and an internal wall, a wheel hub being formed at the center of the internal wall, an opening end being positioned at the external side thereof; b) a plurality of permanent magnets disposed at the internal side of the external ring, thereby forming a rotor; c) a rotational shaft having a bearing unit mounting thereon for supporting the flywheel, one end thereof being provided with a driven wheel for imparting the rotational movement to the rotational shaft and the flywheel; d) a stator iron core having current-generating coils on an external circumference thereof, an iron core-fixing support being attached to the external side thereof, an external bearing being disposed between a central hole of the iron core-fixing support and the rotational shaft; e) a sleeve disposed at a side opposing to the iron core-fixing support, an internal bearing being interposed between the internal circumference of the sleeve and the rotational shaft; and f) a support bracket consisting of an internal support plate and an external support plate, an indentation being formed at the top of the support plates for receiving the sleeve and the iron core-fixing support in place, wherein a self-generated supply is achieved when the flywheel is driven to rotate around the stator iron core; wherein an internal ring between the wheel hub and the external ring of the flywheel is extended from the internal wall toward the opening end; meanwhile, a magnet-conductive ring is mounted on the external circumference of the internal ring; and wherein the internal diameter of the stator iron core is greater than the external diameter of the magnet-conductive ring such that a magnetic field gap is created, and at least one double recessed type ( -shaped) receiving portion is formed in at least one portion of the internal circumference of the stator iron core for receiving one solenoid, and the power required by the solenoid is supplied by the self-generated system such that the solenoid produces a magnetic field that works with the coupled and rotated internal ring to create an eddy-current magnetic resistance so that a reverse resistance acts from the inside on the inertia flywheel.
