| dc.description.abstract | In this study, a small generator was designed, utilizing axially magnetized ring magnets as the stator and PCB side coils as the rotor, generating induced power through rotational excitation. To maximize the utilization of component space while improving generation efficiency, various parameters such as coil turns, size, number of layers, and magnet dimensions were optimized through theoretical analysis and simulation. An improved connection method was adopted to make the multi-layer coil thinner, and adjustments were made to the dimensions between the coil and the mechanical structure to minimize friction. The final generator, measuring approximately 50 mm in diameter and 30 mm in length, was completed through the collaboration of internal and external components. Experimental measurements showed that the induced voltage reached 35.8 Vpp at 600 rpm and 118 Vpp at 2100 rpm. The induced AC voltage can be converted into DC power using a bridge rectifier and filter, providing a power supply to components such as an accelerometer. | en_US |
