This paper presents an equivalent-circuit-based method to experimentally determine the phase inductance and the iron-loss resistance of a switched reluctance machine (SRM). The proposed equivalent circuit of the SRM phase consists of the winding resistance, the winding inductance and the iron-loss resistance. In this paper, the iron-loss resistance is represented as variable with respect to the phase current, the dc supply voltage and the rotor position. The phase inductance is represented as variable with respect to the phase current and the rotor position. The phase winding resistance is represented by a constant parameter. The proposed method allows estimation of the rotary SRM's iron losses for single-pulse operating regimes.
