Design and Performance Comparison of Rotor-Optimized Flux Reversal Machines (FRMs) with Axial and Radial Flux Topologies

Öz

In this study, the electromagnetic performances of radial-flux and axial-flux Flux Reversal Machines (RF-FRM and AF-FRM) are comparatively investigated following rotor-side geometric optimization. To ensure a fair comparison, the current density in the stator windings is kept identical for both machines, while the stator and stator slot geometries are fixed and excluded from the optimization process. This approach is adopted to ensure that the observed performance differences arise solely from the machine topology and rotor geometry. Three-dimensional finite element analyses are carried out using ANSYS Maxwell, and the rotor geometry is optimized through a genetic algorithm with the primary objective of reducing torque ripple. The electromagnetic performance is evaluated in terms of average torque, torque ripple, output power, total losses, efficiency, and torque density. The results indicate that the AF-FRM delivers higher average torque and output power than the RF-FRM, exhibits lower torque ripple, and achieves nearly twice the torque density. Although the total losses of both machines are at comparable levels, the AF-FRM attains higher efficiency due to its increased mechanical output power. These findings demonstrate that axial-flux topologies offer significant advantages for applications requiring high torque density and efficient current utilization.

Bu çalışmada, radyal akılı ve eksenel akılı Akı Terslemeli Makinelerin (RF-FRM ve AF-FRM) rotor tarafı geometrik optimizasyonu sonrası elektromanyetik performansları karşılaştırmalı olarak incelenmiştir. Adil bir karşılaştırma sağlamak amacıyla her iki motor için sargılardaki akım yoğunluğu eşit tutulmuş, stator ve stator oluğu geometrileri sabit kabul edilmiş ve bu bölgelere yönelik herhangi bir optimizasyon uygulanmamıştır. Böylece performans farklarının yalnızca motor topolojisi ve rotor geometrisinden kaynaklanması hedeflenmiştir. Üç boyutlu sonlu eleman analizleri ANSYS Maxwell ortamında gerçekleştirilmiş ve rotor geometrisi genetik algoritma kullanılarak tork dalgalanmasının azaltılması amacıyla optimize edilmiştir. Elektromanyetik performans; ortalama tork, tork dalgalanması, çıkış gücü, toplam kayıplar, verim ve tork yoğunluğu kriterleri üzerinden değerlendirilmiştir. Elde edilen sonuçlar, AF-FRM’nin RF-FRM’ye kıyasla daha yüksek ortalama tork ve çıkış gücü ürettiğini, tork dalgalanmasının daha düşük olduğunu ve tork yoğunluğunun yaklaşık iki katına ulaştığını göstermektedir. Toplam kayıplar her iki motor için benzer seviyelerde gerçekleşmesine rağmen, AF-FRM daha yüksek mekanik çıkış gücü sayesinde daha yüksek verim elde etmiştir. Bu bulgular, eksenel akılı topolojilerin yüksek tork yoğunluğu ve etkin akım kullanımı gerektiren uygulamalarda önemli avantajlar sunduğunu ortaya koymaktadır.
