Klasik elektrik motorları tek serbestlik derecesinde hareket kabiliyetine sahip motorlardır. Çok serbestlik derecesinde hareket gerçekleştirmek istendiğinde birden çok klasik motorun kullanımı söz konusudur. Bu durumda toplam verimin azalması ile sonuçlanmaktadır. Birden fazla serbestlik derecesine sahip olan küresel eyleyiciler çok serbestlik dereceli hareketlerin yapılmasında tercih edilebilirler. Bu çalışmada, yüksek tork yoğunluğuna sahip sabit mıknatıslı bir küresel eyleyicinin 3 boyutlu tasarımı ve sonlu elemanlar metodu kullanılarak manyetostatik analizi gerçekleştirilmiştir. Eyleyiciden düşük hacimde yüksek tork elde edilmesi amacıyla, rotor mıknatıs malzemesi ve stator sargısının fiziksel yapısının optimize çalışmaları yapılmıştır. Yapılan optimizasyon çalışmaları sonucunda mıknatıs malzemesi olarak N50m tipi mıknatıs malzemesi tercih edilmiştir.

INFLUENCE OF ROTOR MAGNET MATERIAL AND STATOR WINDING GEOMETRY ON OUTPUT TORQUE IN SPHERICAL ACTUATOR

Classic electric motors are motors capable of moving in single-degree-of-freedom. It is necessary to use more than one classical motor in order to perform movement in multi-degree-of-freedom. In this case, it results in a reduction in total efficiency. Spherical actuators with multiple degrees of freedom may be preferred for performing multi-degree-of-freedom movements. In this study, 3D design of permanent magnet spherical actuator with high torque density has been realized as well as magnetostatic analysis by using finite element analysis. In order to achieve high torque at low volume, the rotor magnet material and the physical structure of stator winding have been designed optimally. As a result of the optimization studies, N50m type magnet has been preferred as the magnet.
