Abstract :
A major problem of switched reluctance motors (SRM) is the torque ripple, which causes undesirable acoustic noise and vibration. If is caused by saliency of the stator and rotor. In this paper, a novel method on the basis of genetic algorithm (GA) is proposed to reduce the torque dip. thereby reducing the associated torque ripple, with simultaneous increase in torque output using GA. by maximizing the flux linkage and inductance ratio and the results are compared with that produced by a standard 8/6 pole, 4 phase, 1 KW, 100 V, 25 A.1500 rpm SRM. The obtained results are encouraging and verified using finite element analysis (FEA).
