Stability analysis of induction rotors supported in sleeve bearings considering electromagnetic field damping and internal material damping of the rotor

  • The paper shows an analytical rotordynamic model for stability analysis of induction rotors, supported in sleeve bearings, especially considering the influence of electromagnetic field damping and internal material damping of the rotor. The model contains radial and tangential electromagnetic forces considering electromagnetic field damping, stiffness and internal material damping of the rotor structure, stiffness and damping of the support, and stiffness and damping of the oil film of the sleeve bearings. The aim is to unite all these influences in one analytical model and to derive a procedure for calculating the limit of rotor stability.
