A Novel High Energy Density Double Salient Exterior Rotor Permanent Magnet Machine

In this paper, a double salient exterior rotor permanent magnet machine is proposed and analyzed. This machine introduces the use of permanent magnet (PM) into a switched reluctance machine and has the same envelope as that of Toyota Prius third-generation (P3G) 60 kW interior PM synchronous machine (IPMSM). Simulation results show that the continuous torque and peak torque of the proposed machine are 97% and 30.4% more than that of P3G IPMSM under the same current density.
