Abstract

Presented here is a comparison between TORUS and AFIR, the two topologies for double-sided axial-flux permanent-magnet machines. Investigated and compared were their slotted and non-slotted topologies, in terms of power density and torque quality. Field analysis of the topologies was by finite element method. Results show TORUS topology's high power-density in high current-density and low electrical-loading. AFIR topology has high power in low current-density and high electrical-loading. Non-slotted TORUS and AFIR AFPM machines have negligible cogging torque and lower ripple torque than their slotted counterparts.
