This paper describes an electromagnetic energy harvester that uses a rotary-translational magnetic regulation system to convert vibration energy into electrical power. The system consists of a springless magnetic sphere multiple rolling in a cavity and multiple magnetic disks evenly embedded in the cavity. Multiple magnetic disks are arranged with alternating magnetic pole shifts, with the goal of modulating the traditional erratic rolling of the magnetic sphere into a multi-circle regular movement with the change of the magnetic disk’s magnetic pole. Faraday’s law is used to create electromotive forces in coils due to the rotating magnetic moment. The output voltages are measured and analyzed using motion and rotation excitation, parallel, and series coil connections. Experiments on the magnetic sphere with and without magnetic regulation are carried out using a manufactured apparatus. The magnetic sphere with magnetic regulation has periodic and regular output characteristics, according to the results of the experiments. A prototype electromagnetic energy harvester can charge a 0.47 F capacitor to more than 0.40 V in less than 450 s under rotating excitation. The device's energy and effective average power are calculated to be 10.62 J and 23.60 mW.

本文介绍了一种电磁能量收集器，它使用旋转-平移磁调节系统将振动能量转换为电能。该系统由在腔内多次滚动的无弹簧磁球和均匀嵌入腔内的多个磁盘组成。多个磁盘以交替磁极移位的方式排列，目的是随着磁盘磁极的变化，将传统的磁球不规则滚动调制成多圆周规则运动。由于旋转磁矩，法拉第定律用于在线圈中产生电动势。使用运动和旋转激励、并联和串联线圈连接测量和分析输出电压。使用制造的设备对有和没有磁调节的磁球进行实验。实验结果表明，具有磁性调节的磁球具有周期性和规律性的输出特性。原型电磁能量采集器可以在旋转激励下在不到 450 秒的时间内将 0.47 F 电容器充电至 0.40 V 以上。该器件的能量和有效平均功率计算为 10.62 J 和 23.60 mW。
