Abstract:
1. A power generating device, adapted for charging a handheld electronic device, the power generating device comprising: a carrier module, having a bearing; a stator module, assembled to the carrier module, and having a first circuit board and a plurality of driving coils, wherein a current is input to the driving coils through the first circuit board to generate an electromagnetic field; a rotor module, located in the electromagnetic field, and having a multipolar magnetic rotor and a rotating axle, the rotating axle passing through the multipolar magnetic rotor, and one end of the rotating axle being fixed into the bearing, wherein a magnetic field of the multipolar magnetic rotor interacts with the electromagnetic field to make the rotor module rotating relative to the stator module, and make the multipolar magnetic rotor generating a varying magnetic field; and a power generating module, located in the varying magnetic field, and having a second circuit board and a plurality of induction coils, wherein the induction coils induct the varying magnetic field to output an induction current to the second circuit board.
