چکیده مقاله :
اين مقاله به معرفي يک موتور سوئيچ رلوکتانسي 5/6 با رتور قطعه‌اي و بهبود عملکرد آن از طريق ايجاد تغييرات در ساختار رتور مي‌پردازد. با تغيير ساختار رتور، علاوه بر کاهش ريپل گشتاور، بازده موتور نيز افزايش مي‌يابد. موتور ارائه‌شده شامل دو نوع قطب بر روي استاتور است: قطب‌هاي اصلي و قطب‌هاي کمکي. قطب‌های استاتور شرايط را فراهم مي‌آورند تا مسير شار عبوري از مواد فعال کوتاه‌تر شده و نواحي‌اي از سطح رتور که در آنها مسير شار معکوس مي‌شود، در راستاي ايجاد تلفات آهني نقشي نداشته باشند. در اين راستا در اين مقاله توپولوژي‌ها مختلف انواع شيار بر روي رتور بررسي شده و با ارزيابي کارايي موتور بهترين مدل انتخاب شده است. نتايج شبيه‌سازي و تحليل با استفاده از روش المان محدود و مقایسه، کارايي تئوري مطرح‌شده را اثبات مي‌نمايد.
In this paper, a segmental SRM and its performance optimization via making some changes on its rotor is investigated. These changes not only reduce the torque ripple, but also increase the efficiency of the motor. Motor has two types of poles on its stator: main and auxiliary. The auxiliary poles make the flux path shorter and eliminate flux inversion on stator. Different types of notches on rotor structure are examined and the best one is chosen. For simulations, finite element method is utilized.
