چکیده

در این مقاله ساختار جدیدی از چرخ‌دنده مغناطیسی با نام چرخ‌دنده مغناطیسی دولایه قوسی با استفاده از ترکیب ساختارهای شار شعاعی و شار محوری با هدف افزایش چگالی گشتاور انتقالی، معرفی‌شده است. مشخصات عملکردی این ساختار توسط روش تحلیلی جدید شبه سه‌بعدی بهبودیافته (توسعه‌یافته روش تحلیلی دوبعدی)، استخراج و با نتایج حاصل از مدل‌سازی المان محدود سه‌بعدی مورد مقایسه قرارگرفته و برتری و دقت روش معرفی‌شده مورد صحت سنجی قرارگرفته است. این مدل تحلیلی توسط مدل دوبعدی وابسته به مؤلفه‌های مختلف میدان مغناطیسی، مبتنی بر ساختار چرخ‌دنده شار شعاعی و شار محوری معرفی‌شده است تا ساختار دولایه قوسی را با دقت مناسب مدل‌سازی نماید. ساختار ارائه‌شده به‌منظور به‌کارگیری در یک نیروگاه بادی مورد بهینه‌سازی قرارگرفته است. نتایج حاصل از بهینه‌سازی به‌وضوح برتری ساختار مذکور را در مقایسه با ساختارهای متداول چرخ‌دنده‌های مغناطیسی در شاخص چگالی گشتاور ا انتقالی نشان می‌دهد.

چکیده [English]

This paper highlights the future perspective for novel hybrid radial-axial flux structure magnetic gear, named arcuate double-sided magnetic gear (ADSMG) with the aim of higher torque density transmission. Its performance characteristics are quantitatively analyzed using an improved quasi 3-D analytical method (IQAM) computations of magnetic field (which is an improved and amended of 2-D analytical method). Results are verified by 3-D finite-element method simulations to enhance the reliability and precision of the analysis. This modeling is carried out by an effective dependent modeling for the different components of magnetic field distribution, based on axial and radial flux magnetic gear topologies, and modified to accurately model the proposed ADSMG structure. Utilization of proposed IQAM for optimization of ADSMG in a typical wind power application is investigated. It is shown that the optimized ADSMG has significant and superior advantages in terms of torque density than the traditional MGs.
