چکیده :

Axial flux motors are desirable for automotive applications due to their higher power and torque density, compact structure, and superior efficiency. Moreover, motor topology plays a critical role in determining not only the electrical and mechanical performance but also efficiency, torque density, thermal management, cooling capability, manufacturing feasibility, and overall system reliability. Therefore, in this paper, various topologies of axial flux permanent magnet (AFPM) motors are investigated for low-power electric vehicle applications, with a particular focus on electric bicycles. The four considered configurations include: (i) single-sided AFPM, (ii) double-sided yokeless and segmented armature (YASA), (iii) double-sided outer rotor TORUS-NS, and (iv) double-sided outer rotor TORUS-NN. These topologies are compared in terms of weight, cogging torque, total harmonic distortion (THD) of the back-EMF, and power density. The results indicate that, overall, the YASA structure provides the most suitable performance for application in electric bicycles.
