This article proposes a new double-rotor permanent magnet switched reluctance motor (DR-PMSRM). In the proposed topology, the rotors do not include any coils or PMs; therefore, DR-PMSRM inherits the advantages of conventional SRMs. Splitting teeth for each stator pole has resulted in a remarkable increase in the motor’s torque density. In addition, the use of small PMs between the two teeth of the stator poles has greatly improved the output characteristics of the proposed motor compared to the PMless counterpart. The operating principle of the DR-PMSRM is illustrated, and the flux paths created by the coils and PMs have been analytically obtained, which are compatible with the simulation results. The flux distributions, static and dynamic torques, flux linkage profiles, steady-state current, and torque waveforms of the DR-SRM and DR-PMSRM are obtained and compared to demonstrate the effectiveness of PMs. All the simulation results indicate that the PM-assisted structures can achieve higher torque and power than their PMless counterpart. The simulation results confirmed that there is no demagnetizing risk for the PMs used in the structure. Finally, the motor is prototyped, and the experimental results are accomplished. Both the experimental and simulation results confirm the effectiveness of the proposed DR-PMSRM.
