Influence of dynamic magnetic eccentricity on sleeve bearing housing vibrations of induction motors considering electromagnetic field damping

  • The paper shows the influence of dynamic magnetic eccentricity on the sleeve bearing housing vibrations of induction motors, considering electromagnetic field damping. The analytical model contains electromagnetic forces in respect of electromagnetic field damping, stiffness and internal (rotating) damping of the rotor, dynamic magnetic eccentricity, stiffness and damping of the support, and stiffness and damping of the oil film of the sleeve bearings. Based on an analytical rotordynamic model, a practicable method is presented, showing how to consider electromagnetic field damping, when analyzing forced vibrations caused by dynamic magnetic eccentricity, which can also be adopted in a Finite-Element-Analysis.
