چکیده :

Axial Flux Permanent Magnet (AFPM) machines, recognized for their high power density and compact structure, have recently gained significant attention for use in electric vehicles. In electric bicycles, where efficiency and a lightweight design are crucial, electric motors play a key role in overall system performance. In this paper, the design of a Yokeless and Segmented Armature (YASA) AFPM motor specifically developed for electric bicycles is presented. The YASA topology was chosen due to its compact structure and superior power density. To optimize performance, the design was refined using the Taguchi method in combination with finite element method (FEM) analysis. The results indicate that the optimized design achieves a higher average torque while significantly reducing cogging torque and torque ripple. These enhancements nominate the proposed motor as a promising candidate for lightweight, high-efficiency electric bicycle applications.
