Numerical and experimental vibration analysis of a two-pole induction motor mounted on an elastic machine test bed

  • This paper describes the analysis of natural and forced vibrations of a two-pole induction motor mounted on an elastic steel frame foundation. A simplified vibration model is derived which can be used for calculating the natural vibrations in the transversal plane of an electrical motor mounted on a soft foundation. The natural vibrations of the motor are calculated using the simplified vibration model as well as a numerical calculation using a finite element model. These calculations are compared to each other and validated by measurements using experimental modal analysis. In addition to the natural frequencies, also forced vibrations are measured while the motor is operated by a converter. The frequency spectrum is analyzed by using FFT, regarding the forced vibrations.
