Easy and effective multiple faults detection and localization method for PMSM drives

Abstract

In this paper, a new easy and effective multiple faults detection and localization method of total loss position/ current sensors and single open circuit faults in Permanent Magnet Synchronous Motors (PMSMs)drives is presented. This technique requires only information given by errors values obtained from the Root Mean Square (RMS)of the normalized stator currents. The simulation results of multiple faults detection and localization are given to prove that the proposed algorithm leads to convincing results.
