Abstract
In this paper, influence of stator pole embrace on torque of In-Wheel Switched Reluctance Motor (IW-SRM) is investigated by numerical modeling based on Finite Element Method (FEM). For this reason, 3D numerical model of IW-SRM is built by using Ansys Maxwell Software Package. IW-SRM is analyzed and output torque and magnetic flux density of the IW-SRM are calculated. The analysis of IW-SRM is realized for different stator pole embraces and the results of the output torque and magnetic flux density of IW-SRM taken for various stator pole embraces are compared with each other. As seen from the results, when the value of stator pole embrace reduces, the output torque of IW-SRM increases. As a result in this study, the effects of different stator pole embraces are examined on the output torque of IW-SRM.
Highlights
Switched Reluctance Motors (SRM) are simple machines due to important advantages such as high reliability, low maintenance requirement, good performance, low cost and weight, and robust construction [1]
The IWSRM is analyzed for different stator pole embraces which are 0.6, 0.55, and 0.5

Summary
Switched Reluctance Motors (SRM) are simple machines due to important advantages such as high reliability, low maintenance requirement, good performance, low cost and weight, and robust construction [1]. The pole embrace changes the average torque and torque ripple [6] It should be properly selected in design of SRM. By changing the stator and rotor pole embrace from 0.2 to 0.5, FEM analysis is carried out by Ansys Package Software. In [7], the effects of windows in stator and rotor poles of SRMs for decreasing the noise and vibration which are the most disadvantages for SRMs are investigated. Authors in [10] study on the effects of magnetic circuit geometry on characteristics of SRMs. The static and steady state characteristics such as flux linkage, speed, current and torque of the SRM are examined for four magnetic structures which are 8/6, 16/12, 16/14, and 16/18 by FEM analysis.
