从环境中获取能量并为微系统供电的能量收集装置越来越受到人们的关注。本文设计并制作了一种用于振动能量收集的线性发生器。发电机铁芯体积60.8cm3，装置质量338g，设计谐振频率41Hz。来自普通空压机的振动能量被该装置回收利用。振动激励幅值为43µm，频率为60Hz。实验证明，该装置在非谐振情况下可以产生1mW以上的功率。理论上，在谐振情况下可以达到40mW的输出功率。
Energy harvesting device which scavenges energy from the ambient and powers micro systems is receiving more and more attentions. In this paper, a linear generator for vibration energy harvesting is designed and fabricated. Volume of the generator core is 60.8cm3, the mass of the device is 338g, and the designed resonance frequency is 41Hz. The vibration energy from an ordinary air compressor is recycled by the device. Amplitude of the vibration excitation is 43µm at a frequency of 60Hz. Experiments demonstrate that the device can generate more than 1mW in this non-resonance case. In theory, the output power of 40mW can be achieved in the resonance case.
