Öz

Bu çalışmada, 5,5 kW gücünde 22 kutuplu doğrudan tahrikli yüzey yerleştirmeli sabit mıknatıslı senkron motorun (SMSM) tasarımı, analizi ve optimizasyonu gerçekleştirilmiştir. Analitik tasarım aşamasını geçen motorun sonlu elemanlar analizleri için 3 boyutlu modeli oluşturulmuştur. Nadir toprak elementleri tarafından kolayca üretilebilen farklı sabit mıknatıs malzemeleri (Alnico, Seramik, SmCo, NdFeB) kullanılarak motorun vuruntu torku, çıkış gücü, verim ve maksimum çıkış gücü parametreleri incelenmiştir. Yapılan analizlerde, N50m tipi mıknatıs malzemesinde en iyi verim ve maksimum çıkış gücü değeri elde edilmiştir. Ayrıca, en düşük vuruntu torku Alnico5 tipi mıknatıs malzeme ile elde edilmiştir.

Anahtar Kelimeler

• Sabit mıknatıslı senkron motor,sonlu elemanlar analizi,verim,çıkış gücü.

EFFECT OF DIFFERENT MAGNET MATERIALS ON THE PERFORMANCE OF SURFACE MOUNTED DIRECT DRIVE PMSM

Abstract

In the present study, a 5.5 kW, 22 pole direct drive surface mounted PM synchronous motor (PMSM) has been designed, analyzed and optimized. After an initial design stage, a 3D model of the motor has been created for the finite element analysis. Cogging torque, output power, efficiency and maximum output power parameters have been analyzed for various material of PM magnets (Alnico, Ceramic, SmCo, NdFeB), which can be produced easily by rare-earth elements. In the performed analyzes, the best efficiency and the maximum output power value has been obtained on the N50m type magnet material. Furthermore, the lowest cogging torque has been obtained with an Alnico5 type magnet material.

Keywords

• Permanent magnet synchronous motor,finite element analysis,efficiency,output power
