In permanent-magnet synchronous machines (PMSMs) electromagnetic forces are identified as the principal source of vibrations and noises. In this article, first of all the sources of magnetic forces in PMSMs are analyzed. ...

In this article a general analytical model for the analysis of permanent magnet synchronous machines with static eccentricity is presented. The model is a continuation of [1] and it is based on Fourier time-space series ...

Eccentricity is an inevitable fault in electric motors and hence its diagnosis is an important topic. Thus, the influence of static and dynamic eccentricities on the harmonics of the frequency spectra of the unbalanced ...

This paper proposes an automatic detection test of gain faults in current sensors. An offline test is applied when the machine is not operating. The designed test operates at standstill without being necessary to disconnect ...
