Abstract:
1. A magnetically balanced electric generator comprising: a rotor rotating under external force; a fixing structure having a fixing axis rotatably supporting the rotor; a rotating magnet body coupled with the fixing axis in such a manner as to be movable therealong, and engaged with the rotor so as to rotate together with the rotor; a power-generating block installed on the fixing structure while being vertically separated from a lower portion of the rotating magnet body; a first magnet mounted along the circumference of the rotating magnet body; a second magnet mounted along the circumference of the power-generating block and generating a repulsive force while repelling the first magnet, thereby magnetically separating the rotating magnet body from the power-generating block; a plurality of power-generating magnets mounted in the rotating magnet body and rotating about the fixing axis upon rotation of the rotating magnet body; a plurality of power-generating units mounted in the power-generating block such that they are positioned vertically downwards with respect to the power-generating magnet, and generating electricity because of interaction with the power-generating magnet upon rotation of the power-generating magnet; and a gap control unit moving the rotating magnet body with an interaction of an external force so as to control a gap between the rotating magnet body and the power-generating block and therefore a gap between the power-generating magnets and the power-generating core units, variably changing the amount of power generation.
