Farklı Mıknatıs Yapıları ve Farklı Mıknatıs Malzemeleri Kullanımının Küresel Motorun Tasarımına Etkisi

Günümüzde teknolojideki gelişmelere paralel olarak, robotik sistemlerde, tıp alanında, otomotiv sektöründe ve endüstriyeluygulamalarda çok serbestlik dereceli hareket yapabilen motorlara ihtiyaç giderek artmaktadır. Bu sebeple bu çalışmada, çok eksenlihareket kabiliyetine sahip bir sabit mıknatıslı küresel motor tasarımı yapılmış ve ANSYS Maxwell yazılımıyla sonlu elemanlaryöntemiyle (SEY) elektromanyetik analizleri gerçekleştirilmiştir. Analizlerde, motorun rotorunda yer alan farklı mıknatıs türleri vemıknatıs yapılarının yanında, stator ve rotor nüvelerindeki farklı laminasyon türleri de dikkate alınarak motor tasarımları yapılmıştır.Mıknatıs olarak NdFe30, NdFe35, SmCo28 malzemeleri; mıknatıs yapısı olarak gömülü düz mıknatıs, gömülü V-tipi mıknatıs, yüzeymıknatıs; stator ve rotor yapılarındaki laminasyonlar için de steel_1008, M43_24G, JFE_Steel_50JNE300 malzemeleri kullanılarakoluşturulan her bir model için ayrı ayrı elektromanyetik analizler gerçekleştirilmiştir. Her bir tasarım için manyetik akı yoğunluğudağılımının manyetik doyum problemi incelenmiş, moment ve kuvvet değerleri hesaplanmış ve sonuçlar karşılaştırmalı olarakverilmiştir.

The Effect of Using Different Magnet Structures and Different Magnet Materials on the Design of the Spherical Motor

Today, with the advances in technology, the need for motors capable of multi-degree of freedom in robotic systems, medicine, automotive industry and industrial applications is increasing. For this reason, in this study, a permanent magnet spherical motor design with multi-axis motion ability has been designed and electromagnetic analysis has been done with ANSYS Maxwell software using the finite element method. In the analysis, motor designs were made by considering different types of magnets in the rotor and different lamination types in the stator and rotor cores with different magnet structures. Electromagnetic analyzes were performed for each model created using steel_1008, M43_24G, JFE_Steel_50JNE300 materials in stator and rotor structures and NdFe30, NdFe35, SmCo28 materials as magnets with embedded straigt magnet, embedded V-type magnet, surface magnet structures.For each design, magnetic saturation problem of magnetic flux density distribution is examined, moment and force values are calculated and results are given comparatively.
