Modal Analysis and Rotor-Dynamics of an Interior Permanent Magnet Synchronous Motor: An Experimental and Theoretical Study

“…According to the mechanical properties reported in the literature for the concentrated windings (such as switched reluctance machines), the Young's modulus of both slot windings and end-windings is equal. On the other hand, the studies on the asynchronous machine windings (i.e., distributed windings), the Young's modulus of the end-windings (which typically overhang) is higher compared to the Young's modulus of the windings in the slots, due to the additional stiffening process of the end-windings [6,9]. 13 250,364 nodes.…”

“…Such complete mechanical analysis should include both static modal analysis for vibration analysis of geometrical and material properties of the machine components and the rotor dynamics in order to investigate the vibration of the rotating parts. The modal analysis of the machines' stator has already been extensively reported for different types of electrical machines [5][6][7][8][9][10][11][12][13][14], while the rotor dynamic has mostly studied for the mechanical design of high speed machines constructed for special applications [1,2,4,[15][16][17][18][19][20][21][22][23][24][25]. To the best of the authors' knowledge, the complete mechanical analysis of the stator and rotor components of the same machine by the modal and rotor dynamic analysis has not been reported.…”
