Sürekli mıknatıslı senkron motorlar, stator oluklarındaki değişken manyetik relüktans, stator halkalanma akılarındaki bozulmalar ve inverter beslemeden kaynaklanan nedenlerden dolayı moment dalgalanmaları oluşturur. Bu moment dalgalanmaları hızda osilasyonlara neden olur. Bu makalede Sonlu elemanlar Yöntemi ile Sürekli Mıknatıslı Senkron Motorun akı analizi yapılmış ve bulunan sonuçlar moment dalgalanmalarının azaltılması için alan yönlendirmeli kontrolde kullanılmıştır. Önerilen yöntemin geçerliliği Matlab Simulik programı ile ispatlanmıştır.

TORQUE RIPPLE MINIMIZATION OF PERMANENT MAGNET SYNCHRONOUS MOTOR WITH USE OF FLUX MODEL COMPOSED OF FINITE ELEMENT METHOD

Öz

Permanent magnet synchronous motor generate torque pulsations owing to variable magnetic reluctance at the stator slots, distortion of the stator flux linkage distribution, and reasons to based on inverter. This torque pulsations cause speed oscillations. In this paper, flux analysis of permanent magnet synchronous motor with finite element method was made, and the findings were used in field oriented control for to decrease torque pulsations. The validity of proposed method was demonstrate by using Matlab Simulink program.
