Owing to the constraint of the supply voltage, there is a theoretically maximum operating range of the smooth‐torque operation for a switched reluctance drive (SRD). The maximum operating range can be determined by the authors previous work, based on which a novel direct instantaneous torque control (DITC) is proposed for four‐phase 8/6 switched reluctance drive in this study, which can achieve the widest operating range. Compared with the conventional DITC, the proposed DITC does not need the extra optimisation strategy of the switching angle. The performance of the proposed method is identified by simulation and experiment results.
