This paper presents a method of finding the phase current profiles to get minimum torque ripple in switched reluctance motor (SRM) with maximum torque per ampere. The solutions are obtained with peak current limit, finite rise time due to incremental inductance of the phase windings, and the back emf. As these factors are taken into account in obtaining the solution the implementation do not experience the voltage saturation for all the torque levels up to the rated torque. The solutions are obtained using the flux-linkage characteristics and the static torque characteristics. The influence of speed and the bus voltage on the solutions are discussed. All these results are compared with the results obtained by neglecting the effect of inductance and back emf effect. The implementation of the results are carried out on a 4 KW, 4 phase, 8/6 pole OULTON motor using a microcontroller. The simulation and the experimental results are presented.
