Analysis of Unbalanced Magnetic Pull in PMSM Due to Static Eccentricity

This paper presents the analysis of Unbalanced Magnetic Pull (UMP) on the rotor due to static eccentricity. It has been shown in previous research that under eccentric conditions the rotor experiences UMP that constitutes of two components: constant pull and oscillating forces. This paper is divided into two parts. The first part discusses the procedure to estimate static eccentricity in Interior Permanent Magnet Synchronous Machine by analyzing the vibrations that rise due to oscillating forces. The impact of increased load and saturation on constant pull, at a fixed eccentricity, is shown. The second part discusses the aspects of machine design that can make machine more robust, in the case of static eccentricity, to vibrations.
