A gyroscopic power generator that self-accelerates its spinning velocity via positive power feedback is developed. In our previous study, a power of 1.8 W was generated for a gyro-generator, but an external power source was necessary to drive the spinning motor. In this study, the power generated by the precession movement of a flywheel (FW) is applied to the spinning motor. This accelerates the spinning velocity by boosting the feedback voltage. A mathematical model of the generator is presented. Then, the relationships among spin acceleration, generated power, and boost ratio are studied using approximate solutions and numerical analyses. Finally, the validity of the theoretical results is verified by experiment.
