AN LOAD TORQUE OBSERVER OF PERMANENT MAGNET SYNCHRONOUS MOTOR

The article describes uncontrolled load torque estimating problem in Permanent Magnet Synchronous Motor (PMSM). The paper gives an overview of basic approaches in this field. A load torque estimating method in dynamic motor modes is proposed, applying direct speed and current signals measurements in PMSM. The proposed method is based on averaged evaluation of load torque on sliding window. Advantages and features of the proposed method were shown on model and real experiments.

Keywords: Permanent Magnet Synchronous Motor (PMSM), load torque estimation, load torque observer, sliding window
