Abstract

In this study, the effect of rotor pole ratio
coefficient and stator pole ratio coefficient on torque and efficiency in 18/12
pole 3 phase Inverted Switched Reluctance Motor have been investigated. For
this purpose, dimension, electrical and magnetic parameters of 18/12 pole
3-phase Inverted Switched Reluctance Motor have been determined. These
parameters were obtained in our previous study by the heuristic optimization
method according to the determined motor characteristics (efficiency, torque,
etc.). The other dimensions of motor have been kept constant and the effect of
rotor pole ratio coefficient and stator pole ratio coefficient on the torque
and efficiency have been determined according to the fixed and calculated total
ampere-turns values. As a result of the analyzes performed in MATLAB, it has
been observed that there have certain relationships between these coefficients
and torque-efficiency. However, since the effects of rotor pole ratio
coefficient and stator pole ratio coefficient on torque and efficiency are not
exactly linear, it can seen that these coefficients will be considered as
optimization problems in future studies and optimization of these coefficients
will be beneficial in terms of motor performance.
