Sabit Mıknatıslı Senkron Motorlar (SMSM) yüksek moment, yüksek güç yoğunluğu, yüksek hızlanma, küçük hacim, düşük gürültü ve yüksek verimlilik gibi önemli özelliklere sahiptir. Bu özelliklerle, endüstride yaygın olarak kullanılmaktadır. Elektrik motorlarının çalışması sırasında ortaya çıkan olumsuzluklardan biri, dengesiz yüklerin neden olduğu hız dalgalanmaları ve titreşimlerdir. Dengesiz yükler, yükün karakterinin yanı sıra motorun yüke montajındaki hatalar, milin yanlış hizalanması ve yükün kendisinin eksantrik bir yük olmasından kaynaklanabilir. Bu durum özellikle yüksek hızlarda, motorlarda kalıcı hasara neden olur. Farklı nedenlerle ortaya çıkan bu dalgalanmaların belirlenmesi ve ortadan kaldırılması, güvenilir bir çalışma için çok önemlidir. Bu çalışmada, dengesiz yüklü bir SMSM'de dengesiz yük durumları incelenmiş ve motorun dengesiz yükteki hız dalgalanmaları, önerilen uyarlanabilir harmonik enjeksiyon yöntemi ile azaltılmaya çalışılmıştır.

Permanent Magnet Synchronous Motors (PMSM) have important features such as high torque, high power density, high acceleration, small volume, low noise and high efficiency. With these features, is widely used in the industry. One of the negativities that occur during the operation of electric motors is speed fluctuations and vibrations due to the unbalanced loads. Unbalanced loading can be caused by the character of the load, as well as the poor mounting of the motor to the load, the misalignment on the shaft and the load itself being an eccentric load. Especially at high speeds, this causes permanent damage to the motors. Specification and elimination of these fluctuations, which occur for different reasons, are very important for a reliable operation. In this study, unbalanced load situations are investigated in an unbalanced PMSM and the speed ripples in the unbalanced load of the motor are attempted to be decreased by the proposed Adaptive Harmonic Injection approach. The simulation is carried out under various operating conditions by abruptly and linearly changing the motor speed under unbalanced load. It is observed that speed fluctuations in the motor can be effectively suppressed under different operating condition.
