Abstract :
2D and 3D finite-element techniques are used to investigate the influence of geometric asymmetries and the leading dimensions of the stator core, namely the diameter and thickness of the yoke, the width and number of poles, the lamination notches, and the stator windings on the natural frequencies and vibration modes of switched reluctance motors. Predictions are validated against measurements on various experimental models. Both finite-element analysis and experimental measurements are used to quantify the influence of the mass and stiffness of the laminated core and the windings on the natural frequencies and vibration modes, and thereby to obtain the effective material properties
