چکیده :

Synchronous reluctance machines (SynRMs) are now common in many applications, due to their durability and high output torque at a competitive price. However, their application is limited by a high torque ripple and low power factor. To address the power factor, permanent magnets are added to the rotor, making a PM-assisted SynRM. A key challenge is that the magnets can further increase torque ripple, therefore making an optimal barrier design is necessary for boosting performance of the machine. Several methods exist to smooth output torque, including design modification, changing the windings or skewing the rotor. This paper, however, focuses specifically on modifying the design to lower torque ripple without losing other performance factors. We began with designing an standard 1.5 kw, 4-pole SynRM with classic equations. After adjusting barrier shapes based on a reference work, the magnets are inserted into its rotor barriers, keeping the insulation ratio unchanged. the design is optimized to achieve the lowest possible torque ripple. After optimization some some punches are added to the rotor carriers to enhance the torque profile in case of torque ripple. The entire investigation used 2D Finite Element Method (FEM) simulations, and the outcomes are thoroughly examined in this report.
