Abstract

With the increase of the use of permanent magnet synchronous motors, many diagnostic methods to estimate the demagnetization rate of permanent magnets have been studied. This paper is proposing an accurate method to diagnose demagnetization rate based on speed response under the q-axis current excitation. Experimental results show that this diagnostic method can detect demagnetization rate with minimal error.
