This paper proposes a simple method to determine the optimum exciting current, for high output torque in switched reluctance motors (SRMs). By modelling the flux-linkage with one curve at the unaligned position, and with two curves at the aligned position, the maximum increment of the co-energy and torque can be predicted accurately, and the optimum exciting current can also be determined. This easily implemented method is aimed at providing an index for determining the SRM exciting current. This will be useful for SRM designers in deciding the rated current and in obtaining the maximum motor efficiency.
