Bu
çalışmada, yüzey yerleştirmeli kalıcı mıknatıslı senkron generatör tarafından
üretilen tutma torkunu olası en aza indirgemek için stator nüvesinde
gerçekleştirilen yapısal değişiklikler sunulmaktadır. Bu yapısal
değişikliklerin tutma torku ve generatör performansı üzerine etkisi
araştırılmış, 2B-3B sonlu elemanlar analiz (SEA) ve analitik sonuçları
karşılaştırmalı olarak verilmiştir. Tutma torkunun hesaplanması için gerekli
olan hava aralığı akı yoğunluğunun elde edilmesinde manyetik eşdeğer devre ve
bağıl geçirgenlik modeli kullanılmıştır. Hava aralığı ve mıknatıs
bölgelerindeki manyetik alan öncelikle oluk etkisiz olarak hesaplanmış, daha
sonra uygun bir şekilde olukların dâhil edilmesiyle elde edilen bir bağıl
geçirgenlik fonksiyonu (düzeltme faktörü) dikkate alınarak tekrar ifade
edilmiştir. Önerilen yapısal değişikliği ve analitik yöntemi uygulamak için,
4-kW, 24-kutuplu ve 72 oluklu radyal akılı makine tasarlanmış ve optimize
edilmiştir.
