PMASynRM system-level NVH model with eccentricity

Abstract: This paper presents a high-fidelity system-level vibration model for a permanent-magnet assisted synchronous reluctance machine that is able to capture static and dynamic eccentricity effects. The procedure of extracting finite-element data from a series of magnetostaic analyses that include rotor displacement is presented. Afterwards, the flux-linkage state variable system-level model that uses the previous data is developed. Subsequently, the vibration-synthesis method that includes the additional time and s… Show more

“…Eccentricity of electromotor will not only change the internal magnetic field distribution but will also affect the dynamic performance, especially the tangential electromagnetic torque ripple and radial unbalanced magnetic pull, which will lead to the deterioration of noise, vibration, and smoothness [6][7][8]. Many researchers have conducted in-depth and detailed research on eccentric electromotor.…”
