title = "Vibration measurements for validation of electromechanical rotor model for cage induction motor",
abstract = "Eccentric rotor motion of an electric motor induces an unbalanced magnetic pull. This eccentricity force may couple the electromagnetic system with the flexural vibration modes of the shaft. Recently, a simple parametric model was presented for this electromechanical interaction. The aim of this study was to produce experimental data for the validation of this electromechanical rotor model. A standard six-pole 18 kW induction motor was equipped with a long flexible shaft for the experiments. The frequency and damping of the first flexural rotor mode was identified in unloaded steady-state operation. The limit-cycle vibrations and sub-critical unstability was observed in measurements.",
