| Summary: | The paper presents the evaluation study to enhance the design of the motor’s permanent magnet (PM), with the goal of increasing the performance of the segmented stator Permanent Magnet Synchronous Motor (PMSM). The rotor is externally mounted and embedded permanent magnet placed into the groove. By adjusting the width, tip angle, ratio dimension and skew angle of the PMs optimize the magnetic flux flow inside the motor thereby improving performance of the motor under considerations. Finite Element Method (FEM) is used to evaluate for optimizing the parameters to reach the maximum torque through parametric optimization. The numerical results are compared in terms of static torque, cogging torque, iron losses, torque-to-detent torque ratio, and torque constant parameter variations of the models. The findings with optimized flux flow evolve a new type of outer rotor embedded PMSM structure that is fabricated and tested for practical adoption for static and dynamic characteristics. The proposed new type of segmented rotor exhibits low cogging torque with torque ratio of 62 against the conventional structure with value of 14. The proposed model is fabricated and evaluated for its performance against the numerical results and are in close agreement. |
