Eksenel Akı Konseptindeki Senkron Relüktans ve İndüksiyon Motor'un Verim ve Performans Karşılaştırması

Abstract

Efficiency, power density and cost play an important role in motors used in low-power industrial applications. In today's world, where the importance of energy efficiency and compact structure is increasing day by day, the Axial Flux Synchronous Reluctance Motor (AF-SynRM) design, which is a unique motor with no copper loss in its rotor and compact with its axial structure, has been compared with the Axial Flux-Induction Motor (AF-IM) with the same stator structure. Figure A. Rotor parts of two motors (AF-SynRM and AF-IM) with the same stator structure.Purpose: In this study, in two motors with the same stator structure and dimensions; In AF-IM and AF-SynRM, only the rotor part has been changed and the change in output parameters has been examined. Theory and Methods:In the preliminary study of the designs, the motor dimensions were calculated analytically and modeled with the 3D Finite Element Method (FEM). To optimize the saliency ratio, which is the most important factor affecting AF-SynRM performance, a Genetic Algorithm (GA) based optimization was made and the rotor geometry was changed. Results:In comparison, the outer diameter, inner diameter and stator parameters are the same, and the motor efficiency has been increased proportionally by 8.53% with only rotor change, and it has been increased from IE3 to IE4 standards. At full load, the AF-SynRM produced 23.2% more power than the AF-IM Conclusion: Considering the total losses, costs and efficiency values, the AF-SynRM design will be an alternative to the AF-IM compared with reference. In future studies, experimental comparison of AF-SynRM, which goes through production processes, with AF-IM will also be possible. In addition, designs of AF-SynRM with permanent magnets can also be designed and the comparison procedure can be repeated. Highlights• Motor Design. • Axial Flux.• Finite Element Method.
