Elektrikli Araçlar için Yüksek Verimli Çift Hava Aralıklı Eksenel Akılı Senkron Relüktans Motorun Geliştirilmesi: Mıknatıs Desteğinin Etkisi

Öz

Bu çalışma, düşük hacim, düşük kayıp ve yüksek verimlilik özelliklerine sahip ve elektrikli araçlar için Eksenel Akılı Senkron Relüktans Motoru (EA-SRM) tasarımını geliştirmektedir. Çift hava aralıklı (çift rotor ve çift stator), farklı kutup sayısına sahip (6-8-10 kutup) EA-SRM 2D lineer modelleri mıknatıs durumuna (Mıknatıssız, ferrit mıknatıs destekli ve nadir toprak elementi mıknatıs destekli) göre Sonlu Elemanlar Yöntemi (SEY) kullanılarak test edilmiştir. EA-SRM modeli için hava aralığı topolojisi, kutup sayısı ve mıknatıs etkisi tork, güç ve verimlilik açısından kıyaslanmıştır. Bu çalışmada çift hava aralıklı EA-SRM tasarımının literatürdeki eksikliğinin giderilmesi ve 2D lineer modeller kullanarak tasarım sürecindeki işlem yoğunluğunu minimuma indirmek amaçlanmıştır. 10 kutuplu mıknatıs destekli EA-SRM modeli, 1.87 Nm/A tork/akım oranı, 4.8 kW/kg güç yoğunluğu ve %92.75 verimlilik sergilemektedir. Bu çalışma sayesinde EA-SRM’ye ait 18 farklı model ilk tasarım sürecine katkıda bulunmuştur. Yüksek tork, güç ve verim açısından optimum modelin ortaya çıkarılmasını sağlamaktadır.

Development of a High-Efficiency Double Air Gap Axial Flux Synchronous Reluctance Motor for Electric Vehicles: Effect of Magnet Assistance

Öz

This study develops the Axial Flux Synchronous Reluctance Motor (AF-SynRM) design with low volume, low loss and high efficiency has been preferred for use in EV. Double air-gap AF-SynRM 2D linear models with different pole numbers (6, 8, and 10) were tested using the Finite Element Method (FEM). The magnet condition was considered (magnet-free, ferrite magnet-assisted, rare-earth magnet-assisted). The models were compared in terms of torque, power, and efficiency. This study aims to address the lack of 2D linear models and reduce the computational intensity in the design process. The 10-pole magnet-assisted AF-SynRM model exhibits a torque/ampere ratio of 1.87, a power density of 4.8 kW/kg and efficiency of 92.75%. This study used 18 different AF-SynRM models in the initial design process, ensuring the optimal model emerges in terms of high torque, power, and efficiency.
