Abstrakt: This paper focuses on designing a coaxial motor structure in the context of the modularization approach, aiming to enhance flexibility in adjusting power (torque) to suit userspecific requirements. The effectiveness of this proposal is verified through the analysis of the torque production by using the mathematical model. Subsequently, two methods: the geometric method and the stationary state method are presented to encounter the commutation synchronization between modules, which affects the motor performance and the smoothness of the start-up period. Furthermore, the mutual interaction between the magnetic fields generated by each module in the same cluster is analyzed based on the simulation results from Ansys software. Finally, the comparisons of experimental results on current and speed are conducted among the modular coaxial BLDCM prototype with differing numbers of modules to validate the correlation between theoretical calculations and practical outcomes.
