Study on Motor-Driven Gyroscopic Power Generator

―Self-Acceleration by Power Feedback―

Abstract

A motor-driven gyroscopic power generator is developed that self-accelerates its spinning velocity by a power feedback. In our previous report, a power generation of 1.8 W was confirmed by a gyro generator, but an external power source was used to drive the spinning motor. In this research, a method is presented to apply the power generated by the precession movement to the spinning motor and accelerates the spinning velocity by the voltage feedback and boosting. In this paper, first, a mathematical model of the generator is presented and the relationship among the spin acceleration, generated power and the boosting ratio are numerically studied. Next the generated powers of 2.5" and 3.5" flywheel generators are calculated to show the possibility of 0.84W and 2.2W respectively. Finally, the validity of the theory is verified by the experiment.
