Abstract:
1. A rotation power generating device comprising: a stator including a plurality of stationary units shaped into rings of the same diameter and vertically connected to one another, each of the stationary units having a pair of stationary magnets embedded inside an inner surface thereof at symmetric positions such that identical polarities face each other, a portion of the inner surface covering each stationary magnet installed to protrude inward defining a gentle streamlined surface within a predetermined angular range at one side thereof and a vertical end surface at the other side thereof; and a rotator including a plurality of rotating units vertically connected to one another with an angular orientation difference therebetween and each having a pair of rotating magnets arranged to face the corresponding stationary magnets of the same polarity so as to be rotated along the inner surface of the corresponding stationary unit, with a gap from the inner surface, about a rotating shaft that is installed in the center of the stator, each of the rotating magnets being provided at a distal end thereof with a ball bearing to be smoothly rotated on the streamlined surface in close contact therewith, and being connected to the rotating shaft via an elastic member in which a spring is installed.
