Abstract

This paper focuses on a permanent magnet assisted synchronous reluctance machine with eccentric rotor, comparing with concentric rotor case, in terms of their vibration level. A 4 pole/36 slots permanent magnet assisted synchronous reluctance machine is adopted in this paper as a case study. An analytical model for predicting the airgap flux density and the electromagnetic force is firstly proposed. This is then validated by means of finite element simulations. The objective of the paper is to understand and compare the vibration level in a permanent magnet assisted synchronous reluctance machine in case of eccentric rotor position. To this aim, both static and dynamic eccentricity conditions are analyzed and compared based on finite element vibrational analyses.
