A nonlinear modeling of a two-tooth per stator pole switched reluctance motor (SRM) is carried out using Pspice. Static test data of flux-linkage and torque for different rotor positions from the aligned to the unaligned position for various stator winding excitation currents of the SRM were available. The flux-linkage versus rotor angular position and stator current are fitted with an analytical equation and its coefficients are determined. The electrical part of the motor is modeled by the induced back-electromotive-force (emf) and mechanical part by torque versus rotor position and stator winding current.
Performance of the model is studied using a
conventional inverter and the simulation results are compared with test and other simulation results. It is shown that Pspice modeling based on the static test data is n10re accurate than those obtained numerically by the same data and Pspice modeling with the flux-linkage curves.
