Abstract
Bu çalışmada genellikle hızlı raylı taşımacılıkta kullanılan çelik sekonderli iki yanlı lineer indüksiyon motor modellendi. Modelde iki boyutlu sonlu elemanlar alan analiz yöntemi kullanıldı. Statordaki manyetik doyma hesaplamalara dahil edildi. Çözümde her eleman için B-H eğrisi kullanılarak \mu, B, H değerleri bir iterasyonla bulundu. İtme kuvveti hesaplandı. 4 Kutup için akı yolu çizildi. Hesaplanan sonuçlar yük altında yapılan deneylerle doğrulandı.
In this paper a short-primary with a steel-sheet secondary type linear induction motors, which is generally used in high-speed ground transportation, is modeled. The model is obtained from the field analysis using FE in x-y plane. Saturation in the stator is taken into account. The solution is found by iteration and adjustment of \mu for the elements until \mu, B, H coincide on the B-H curve. The flux pattern for a 4-pole machine is drawn. Computational results are verified by experimental measurements under variable frequency and loading conditions.
