摘要
This article presents the analysis of the noise characteristics for the planar switched reluctance motor to enrich performance evaluation of the planar switched reluctance motor. The mechanical structure, electromagnetic force, and control scheme are first presented. An analytical mathematical model of sound intensity is then proposed to characterize the relationship between the mechanical structure and the noise. An improved mechanical structure is further designed and analyzed to decrease the deformation by using ANSYS Workbench. Furthermore, an experimental setup of noise measurement is built based on the developed planar switched reluctance motor. In addition, the noise is measured experimentally under the open-loop and closed-loop motions after performing the experimental measurement of ambient noise. The experimental results demonstrate that the planar switched reluctance motor is capable of achieving low-noise motion.
