N2 - The magnetic focusing effect of Halbach array has a wide range of applications in many areas. In this paper, based on the general theory of static magnetic field, various factors affecting the energy harvesting output voltage of Halbach array are analyzed. After that, according to the simulation carried out by Comsol, the magnetic field distribution of the four module Halbach array with different numbers of magnets was obtained, which verified that the shape of the magnetic field was a periodic sinusoidal distribution converging on one side. Then a Halbach array rotor was designed, and the output voltage of the Halbach array energy harvesting structure with different numbers of magnets under the influence of different factors was simulated, and the optimal Halbach array energy harvesting structure was obtained. At the same time, the halbach array composed of 12 magnets was verified through experiments. The experimental results are consistent with the simulation results, and higher voltage and higher power can be obtained. The designed Halbach array with simple structure and small size, can be more suitable to the lower frequency vibration or motion.
