Abstract
Bu çalışmada elektromanyetik kornanın mevcut bir tasarımı ele alınarak manyetik analizi yapılmış ve analiz sonuçları deneysel sonuçlar ile karşılaştırılmıştır. Elde edilen başarı oranı, korna sisteminin imalat öncesi bilgisayar ortamında analiz ve doğrulanmasını sağlamada etkin bir rolü olacağı göstermiştir. Manyetik alan kuvvetinin; zamana, akıma ve hava aralığına bağlı değişimi SEM ile çözülmüş olup ayrıca manyetik akının hava aralığına bağlı değişimi analiz sonucunda görülmüştür. Elektromanyetik alan oluşumunda bobin teli malzemesinin etkisini belirlemek için bakır ve alüminyum bobin teli kullanılarak analizler yapılmış ve sistem güç kayıpları gösterilmiştir. Bu kayıplara göre alüminyum bobin teli için kayıp değerleri 3.54 W olarak hesaplanırken bakır bobin teli için kayıp 2.30 W olarak hesaplanmıştır. Bu durum, kornanın daha fazla akım çekmesiyle ilişkili olup bu etki yapılan ölçümlerle doğrulanmıştır.
In this study, the magnetic analysis of an existing electromagnetic horn design was conducted, and the analysis results were compared with experimental results. The achieved success rate has been shown to play an effective role in ensuring the analysis and validation of the horn system in a computer environment before manufacturing. The variation of the magnetic field strength with time, current, and air gap was solved using SEM, and the change in magnetic flux with respect to the air gap was observed in the analysis results. To determine the effect of the coil wire material on the formation of the electromagnetic field, analyses were conducted using copper and aluminum coil wires, and the system's power losses were demonstrated. According to these losses, the loss value for the aluminum coil wire was calculated as 3.54 W, while the loss for the copper coil wire was calculated as 2.30 W. This situation is associated with the horn drawing more current, and this effect was verified through the measurements taken.
