In this paper, a novel dual-PM spoke-type flux-reversal machine (dual-PM SFRM) is proposed. Tangentially-magnetized PMs sandwiched with iron pole set in stator slots. To increase the torque density within the geometric restrictions, PMs are introduced in the rotor as well and magnetized radially to form a consequent-pole rotor. Global optimizations are conducted and comparisons are made on torque, torque ripple, and torque/PM volume with the existing single-PM spoke-type flux-reversal machine (single-PM SFRM), which show the proposed dual-PM SFRM can produce 12.1% larger torque with an optimal PM volume and a 7.9% larger torque with the same PM volume.
