| چکیده | ||
| Background and Objectives: Synchronous reluctance motors (SynRMs) have considered as energy-efficient alternatives to conventional induction motors (IMs), primarily due to high efficiency. Despite their low losses, SynRMs are hindered by inadequate line-start capability and a low power factor, which restrict their use in industrial settings. This article addresses these limitations by introducing a line-start permanent magnet-assisted SynRM (LS-PMaSynRM) that incorporates fluid-type flux barriers. This design aims to enhance starting performance and increasing power factor. Methods: The design process entailed a parametric sensitivity analysis of critical motor characteristics, including rotor geometry, stator winding configuration, and stator slot count. Finite Element Method (FEM) simulations were executed using time-stepping analysis to assess the motor's electromagnetic behavior under both transient and steady-state conditions. Performance metrics such as torque ripple, average torque, efficiency, and power factor were evaluated. Comparative simulations with conventional SynRM and PMaSynRM designs were also conducted to benchmark improvements. Results: The proposed LS-PMaSynRM exhibited substantial enhancements in line-start capability, achieving stable synchronization within a brief period. The motor demonstrated a significant increase in power factor relative to conventional SynRM designs, while maintaining high efficiency throughout the operating range. Conclusion: The study presents an LS-PMaSynRM architecture that effectively addresses traditional limitations in line-start performance and power factor. These findings support the broader industrial adoption of SynRMs and offer a practical design pathway for future high-efficiency motor applications. | ||
