Study on Gyroscopic Power Generator Excited by Vibration

研制了一种以人体运动为能源的高效发电机。发电机转子直径26mm，功率0.1 w。它的发电量是传统振动发生器的100倍以上。它从2Hz的振动中产生约3600 rpm的三维旋转。为了稳定转子的旋转，研究了理论稳定性分析、电磁阻尼被动控制和发电机自激旋转等技术。

A highly efficient power generator is developed that uses human movement as the energy source. The generator has a rotor with diameter of 26mm and generates power of0.1W. It is more than 100 times higher in power generation than that of conventional vibration generators. It produces 3 dimensional rotations of about 3600 rpm from vibration of 2Hz. In order to stabilize the rotor rotation, several techniques are developed such as a theoretical stability analysis, a passive control of electro-magnetic damping and aself-activation of rotation using the generator as a motor.
