摘　　要：发电机在许多电气领域得到应用,设计了一种限幅激励发电机。通过非接触激励旋转磁铁来实现凸轮往复振动,通过凸轮为压电振子提供接触激励作用。开展实验测试分析,研究结果表明:逐渐提高弹簧刚度后形成更大最佳转速与带宽,凸轮限幅激励满足有效性,大幅减小转速域中的电压波动幅度。输出电压与转速存在峰值最优转速,提高激振力可以使各输出电压下形成更大有效带宽,输出电压发生了大幅波动。该研究有助于增强发电机运行可靠性,改善转速适应能力。The generators have been used in many electrical fields.A limiting excitation generator has been designed,which can realize the reciprocating vibration of the cam by the non-contact excitation rotating magnet,and can provide the contact excitation action for the piezoelectric vibrator by the cam.Through the analysis of experimental test,the research result shows that the greater optimal speed and bandwidth of the spring can be obtained by gradually increasing the stiffness of spring,the limiting excitation of cam can satisfy the effectiveness,and the voltage fluctuation amplitude in speed region can be reduced greatly.The output voltage and speed have the optimal peak speed.Increasing the excitation force can make the effective bandwidth of each output voltage become larger and the output voltage fluctuate greatly.This research is helpful to enhance the operation reliability of generator,and improves the speed adaptability.
