  The switched reluctance (SR) motor is low cost, extremely robust, and has a wide range of variable speeds. However, its power density is generally inferior in comparison with conventional permanent magnet (PM) motors. This paper presents a novel SR motor that has auxiliary windings and permanent magnets in the stator yoke. It operates similarly to a conventional SR motor in the motoring mode. On the contrary, it operates as a permanent magnet reluctance generator (PMRG) in the generating mode. The basic characteristics of the proposed SR apparatus operating as a motor and generator were calculated by using the finite element method (FEM), and compared with those of conventional reluctance machines.
