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. 

Keywords
