In this paper, a practical way of measuring the mutual flux in a switched reluctance (SR) motor is explained and the test results for an 8/6 pole, 4 kW motor are presented. The performance of the drive is studied in simulation with and without mutual flux. The effect of mutual flux on phase current, flux and average torque is demonstrated with the simulation result. Further, the effect of the same on position estimation is verified in simulation and experiment. It is shown that appropriate correction for mutual flux may improve the accuracy of the estimated position by 3/spl deg/.
