Elektrik Makinelerinde Hairpin Sargı Teknolojileri ve Uygulamaları

Öz

Bu çalışmasında, elektrik makinelerinde son yıllarda yaygınlaşan hairpin (dik-dörtgen iletkenli) sargı teknolojisi çok boyutlu olarak ele alınmıştır. Çalışma; hairpin sargının temel prensiplerini, geleneksel yuvarlak kesitli tel sargılarla farklarını, elektromanyetik ve termal davranışını, üretim süreçlerini, yalıtım ve güvenilirlik konularını ve başlıca uygulama alanlarını kapsamaktadır. Özellikle elektrikli araç tahrik motorlarında önemli bir parametre olan oluk doluluk oranı, güç yoğunluğu, AC kayıpları, NVH (gürültü-titreşim-sertlik) etkileri, maliyet ve seri üretime yatkınlığı arasındaki tasarım kısımları ele alınmıştır. Ayrıca literatürdeki güncel yaklaşımlar doğrultusunda çok fizikli modelleme, gelişmiş malzemeler, bağlantı (kaynak/brazing) kalitesi değerlendirilmiştir

Anahtar Kelimeler

• Hairpin sargı
• elektrik makinesi
• AC bakır kayıpları
• doluluk oranı
• elektrikli araç

Hairpin Winding Technologies and Applications in Electrical Machines

Öz

This study comprehensively examines hairpin (rectangular conductor) winding technology, which has become widespread in electrical machines in recent years. The study covers the basic principles of hairpin winding, its differences from traditional round wire windings, its electromagnetic and thermal behavior, manufacturing processes, insulation and reliability issues, and its main application areas. In particular, the design aspects concerning slot filling ratio, power density, AC losses, NVH (noise-vibration-harshness) effects, cost, and suitability for mass production—all important parameters in electric vehicle drive motors—are addressed. Furthermore, in line with current approaches in the literature, multi-physics modeling, advanced materials, and connection (welding/brazing) quality are evaluated

Anahtar Kelimeler
