Abstract

Axial flux motors
are one of the promising motor types in the literature due to the advantageous
specifications. They provide crucial advantages against the radial flux motors
in contrast to moving torque by the volume and the weight. Since the motors
that have sinusoidal back emf have lower torque ripples, the adduction of back
EMF waveform to the sinusoidal by applying the stepping and shifting on the
rotor magnets and the mitigation of the torque ripples is researched in this
paper. Shifting and stepping method is applied to the rotor magnet in the 3D
analysis to realize that. Moreover, to get the best results, the optimum
initial position is determined before the back emf and moving torque analysis.
While analyzing, the optimum value of the moment is found in contrast to the
different initial positions. In addition to that, mean torque values versus
initial positions is illustrated as a rectangular plot.

Yüzey Mıknatıslı Eksenel Akılı Motorlarda Rotor Mıknatıslarına Adım Ve Kayma Uygulanarak Moment Dalgalanmasının Azaltılması

Abstract

Eksenel akılı sürekli mıknatıslı
motorlar avantajlı özellikleri bakımından literatürde öne çıkan motor
türlerinden birisidir. Radyal akılı motorlara göre hacim veya ağırlık başına
moment açısından önemli avantajlar ortaya koymaktadır. Bu makalede ise sinüs
zıt EMK dalga şekli olan motorların daha az moment dalgalanmasına sahip olması
nedeniyle, eksenel akılı sürekli mıknatıslı motora ait zıt EMK dalga şeklinin
sinüse yaklaştırılması ve buna bağlı olarak moment dalgalanmasının azaltılması
araştırılmıştır. Bunu gerçekleştirebilmek için eksenel akılı sürekli mıknatıslı
motorun rotorunda bulunan mıknatıslara adım ve kayma açısı uygulanarak üç
boyutlu analiz yapılmıştır. Ayrıca zıt EMK ve moment analizinden önce, en doğru
sonucu elde edebilmek için, rotor konumunun en iyi pozisyonu belirlenmiştir.
Analiz yapılırken çeşitli başlangıç değerlerine bağlı olarak ortaya çıkan en
iyi moment değeri bulunmuştur. Bununla beraber de ortalama momentin başlangıç
pozisyonuna bağlı olarak değişimi de grafiksel olarak gösterilmiştir.
