Summary
This paper presents a design concept for yokeless and segmented armature axial flux machines incorporating a hybrid additive-subtractive manufacturing process. The design emphasises both repairability of individual stator subcomponents and thermal management to accommodate low-temperature polymer housings. Multi-domain numerical simulations verified the design meets performance and thermal requirements, pending experimental validation.
Key measures
Torque density, axial length, thermal performance, mechanical integrity under operational conditions (via finite element analysis)
Outcomes reported
The study developed and numerically validated a design concept for YASA axial flux machines that integrates additive and subtractive manufacturing whilst enabling component remanufacturing and managing thermal constraints imposed by polymer housing materials. Simulation results across electromagnetic, thermal and mechanical domains demonstrated the concept meets specified requirements, though experimental validation is pending.
