Modeling of switched reluctance motor using Fourier series for performance analysis.

A computational method for a performance analysis of the switched reluctance motor has been developed. Most of the papers present static characteristics, such as static torque based on a finite element method analysis. However, this method is based on a Fourier series expansion with step-by-step, current-dependent, adjustable coefficients. Analytical expression for the calculation of instantaneous phase inductance, flux linkage, co-energy, and electromagnetic torque as a function of rotor position and winding current are derived. Finally, the strategy to represent the winding inductance variation with position is made by approximating the actual inductance profile. [ABSTRACT FROM AUTHOR]
