Abstract

Axial Flux Motors (AFMs) possess extreme torque density, yet traditional topologies limit internal cooling. This paper proposes a disruptive AF-MCE (Axial Flux - Magnetocaloric Effect) architecture, replacing conventional silicon steel stators with insulated La-Fe-Si magnetocaloric alloys. By integrating a planetary reduction gearset, this topology lowers the intrinsic alternating magnetic frequency to mitigate eddy current losses, establishing a solid-state Active Magnetic Regenerative (AMR) cooling cycle directly within the motor's core.
