چکیده

در این مقاله ساختاری جدید از گیربکس مغناطیسی ارائه شده است که می‌تواند عملکرد بهتری را در مقایسه با نمونه‌های متداول از خود نشان دهد. هدف این کار بررسی یک نوآوری در ساختار فیزیکی گیربکس مغناطیسی می‌باشد که باعث شده میدان مغناطیسی توزیع مناسب‌تری در ماشین داشته باشند. تنظیم موقعیت آهنرباها در طرح جدید سبب توزیع بهتر شار مغناطیسی می‌شود و در نتیجه عملکرد ماشین نسبت به نمونه‌های مرسوم بهبود می‌یابد. در ضمن، تغییرات ذکر شده، این امکان را پدید می‌آورد که میزان چگالی شار در فاصله هوایی افزایش یابد و همچنین سامانه ، پایداری بالاتری داشته باشد. گیربکس مغناطیسی جدید با ابعادی کوچک‌تر از طرح های پیشین،  علاوه‌ بر این‌که مقدار گشتاور انتقالی افزایش یافته است، ماشین نوسان کمتری را تجربه می‌کند. نتایج شبیه‌سازی‌ها مبتنی بر روش اجزاء محدود می‌باشد و با استفاده از نرم‌افزار تحلیل الکترومغناطیسی Maxwell ANSYS محاسبات و اعتبارسنجی مورد نظر انجام گرفته است.

چکیده [English]

This paper presents a new structure in the magnetic gearbox field, which can bring better performances rather than the conventional one. This work aims to describe a developed magnetic gear with a novelty in its physical structure which cause gearbox can experience a new magnetic field distribution. Having experienced a further distribution in its magnets plan, the new model can reveal better performances rather than the original coaxial gearboxes. Although dimensions of the new coaxial gearbox get smaller than the ones in typical design, torque transfer and fluctuating rates have incredibly improved. Simulation results, based on the proposed models, are extracted from a time-stepping finite element analysis. ANSYS Maxwell software uses the Finite Element Method in its calculations and reports the results to validate the magnetic systems operations.
