Abstract
In parallel with the increased production of electric vehicles, the research on electric motors has become very popular. Switched Reluctance Machines (SRMs) have been widely preferred in these investigations. Mutually Coupled Switched Reluctance Machine (MCSRM) has higher torque performances than conventional SRMs have. In this study, it is aimed to reduce the weight of MCSRM by geometric arrangement. For this purpose, the MCSRM’s stator yoke is minimized without deteriorating the flux distribution. Various geometrical changes are performed on the stator yoke of the MCSRM. Each of the obtained motor models is magnetostatic analyzed in different currents by finite-element analysis. From comparison of the results of the analysis, it is seen that the proposed MCSRM models show reduction in the stator volumes between 11.31% and 14.17%. This reduction leads to a reduction in the overall weight of the MCSRM.
