Accurate modelling and modal analysis of stator system in permanent magnet synchronous motor with concentrated winding for vibration prediction

This study investigates the accurate modelling and the modal natural frequencies of the stator system of a permanent magnet synchronous motor with concentrated winding used in the in-wheel motor system of the electric vehicle. The equivalent material physical properties of each component in the stator system are determined by the correction formula and the empirical coefficient. Meanwhile, the con...
