CONSIDERATIONS ON THE MODAL ANALYSIS AND VIBRATION SIMULATION OF INDUCTION MOTORS

Ioan-Claudiu COŢOVANU, Iulian LUPEA

Abstract


The article is observing the vibration numerical simulation of induction electric motors by using finite elements method, with particular focus on the modal analysis. Several other dynamic simulations like the frequency responses to harmonic, random excitations and mechanical shocks are shortly presented. The importance of the modal analysis is highlighted from theoretical and experimental point of view, on one hand, and by performing and commenting several simulations on electric motors components (housing, rotor and stator) and the assembled structure, on the other hand.

Keywords: induction electric motor, frequency response, modal analysis, experimental modal analysis.
