In this study, the design an‎d simulation of an electric drive system for a Radial Wound Axial Flux Permanent Magnet (RWAFPM) motor have been carried out. This type of motor, due to its unique structure, modular design, yokeless stator, an‎d special winding configuration, offers advantages such as high torque density, favorable efficiency, an‎d ease of construction. However, issues such as high torque ripple an‎d phase imbalance hinder its optimal utilization, making the development of an appropriate control system essential. Accordingly, a three-dimensional model of the motor was developed using the finite element method (FEM) in Altair Flux software, an‎d its key parameters were extracted. The resulting model was then imported into MATLAB/Simulink, where a Field-Oriented Control (FOC) strategy—recognized as one of the most advanced control methods for permanent magnet motors—was implemented. Simulation results demonstrate that the proposed controller significantly reduces torque ripple, improves the motor’s dynamic response, an‎d ensures stable system performance. Rather than focusing on physical modifications to the motor, this research adopts a control-based approach to optimize its performance. The findings confirm that with a precisely designed electric drive, the efficiency an‎d practicality of this type of motor can be enhanced for industrial an‎d electric transportation applications.
