[ 1 ] - بررسی تأثیر تغییر شکل مغناطیس‌های دائم بر گشتاور دندانه و نیروی محرکه القایی یک ژنراتور مغناطیس دائم شارمحوری به کمک روش المان محدود
گشتاور دندانه ماشین‌های مغناطیس دائم شارمحور (AFPM) در حالت عادی و در مقایسه با ماشین‌های شار شعاعی بالا است. چگالی توان، گشتاور دندانه، مشخصه‌های گشتاور سرعت و بازده ازجمله پارامترهایی هستند که در طراحی ژنراتورها حائز اهمیت هستند. در این مقاله آثار تغییر و انحراف شکل مغناطیس‌های دائم روتور بر عملکرد ژنراتور مطالعه شده است. شکل بهینه آهنرباهای روتور به‌منظور کاهش گشتاور دندانه و به دست آوردن تو...
[ 2 ] - A New Method for Computation of Axial Flux Permanent Magnet Synchronous Machine Inductances under Saturated Condition
Accurate computing of the saturated inductances of Permanent Magnet Synchronous Machine (PMSM) is very important during the design process. In this paper, a new method is presented based on the B-H characteristic of the stator material and unsaturated inductances formulations. This method is used to calculate the saturated inductances of the axial flux PMSM. The synchronous inductance and all o...
[ 3 ] - Comprehensive Parametric Study for Design Improvement of a Low-Speed AFPMSG for Small Scale Wind-Turbines
In this paper, a comprehensive parametric analysis for an axial-flux permanent magnet synchronous generator (AFPMSG), designed to operate in a small-scale wind-power applications, is presented, and the condition for maximum efficiency, minimum weight and minimum cost is deduced. Then a Computer-Aided Design (CAD) procedure based on the results of parametric study is proposed. Matching between t...
[ 4 ] - Discrete Time Control Method for SVM Direct Active Power and Stator Flux Control of PMSG-Based Wind Turbine
This paper proposes a new method for direct control of active power and stator flux of permanent magnet synchronous generator (PMSG) used in the wind power generation system. Active power and stator flux are controlled by the proposed discrete time algorithm. Despite the commonly used vector control methods, there is no need for inner current control loops. To decrease the errors between refere...
