Abstract

The choice of SRM design depends on the specific application and performance requirements. Factors such as power output, torque characteristics, and efficiency will all influence the choice of SRM design. To find an optimal geometry, it is therefore necessary to determine the effect of each parameter such as rotor pole angle, stator pole angle, stator external diameter, rotor diameter, air gap length, rotor yoke, stator yoke and shaft diameter on the machine performance. For this reason, this paper discusses a comparative study of the geometric parameters influence on SRM performance. The analysis is performed by finite element simulations based on the variation of rotor inclination, air gap length, stator and rotor polar arc variations of three machine topologies such as the three-phase 12/8 SRM, three-phase 6/4 SRM and four-phase 8/6 SRM. For a reliable comparison, these machines must have the same basic dimensions (stator outer diameter, rotor outer diameter and length) and operate in the same magnetic circuit saturation. Graphical and numerical results of torque and magnetic flux for three SRM topologies are highlighted. The presented study aims to provide reliable results on the dimensions to be adjusted for various applications.

利用有限元分析优化可再生能源应用中开关磁阻机的几何参数

SRM 设计的选择取决于具体应用和性能要求。功率输出、扭矩特性和效率等因素都会影响 SRM 设计的选择。因此，为了找到最佳几何形状，有必要确定转子磁极角、定子磁极角、定子外径、转子直径、气隙长度、转子轭、定子轭和轴直径等各参数对机器性能的影响。因此，本文讨论了几何参数对 SRM 性能影响的比较研究。分析是通过有限元模拟进行的，基于三种机器拓扑结构（如三相 12/8 SRM、三相 6/4 SRM 和四相 8/6 SRM）的转子倾角、气隙长度、定子和转子极弧变化。为了进行可靠的比较，这些机器必须具有相同的基本尺寸（定子外径、转子外径和长度），并在相同的磁路饱和度下运行。重点介绍了三种 SRM 拓扑的扭矩和磁通量的图形和数值结果。本研究旨在为各种应用提供可靠的尺寸调整结果。
