| Abstract |
The double-salient (DS) machines combine the advantages of variable reluctance structure with the permanent magnet (PM) excitation, the switched reluctance machine (SRM), which belongs to the DS machines class, is the only one that has no PM excitation. Since the phase flux linkage of a DS machine varies with the rotor position and the phase current, the circuit-type mathematical model can not cover adequately the phenomenon. In the paper is presented a method, and the corresponding computer program, to calculate the transient and steady state characteristics of the DS machines. The computation is based on a simplified circuit-field mathematical model of the DS machines, which is not supported by finite element method (FEM) analysis. The program, which can be integrated in a sizing-dimensioning procedure, allows the driving system and DS machine supply source to be taken into consideration. The results obtained by computing the transient characteristics for two DS machines stand by to prove the program accuracy and versatility. |
