ABSTRACT: The paper presents a theoretical analysis of
different vibration control strategies of soft mounted induction motors with
sleeve bearings, using active motor foot mounts. After the vibration model is
presented, different controllers in combination with different feedback
strategies are mathematically investigated. The focus is here on the forced
vibrations, caused by dynamic rotor eccentricity—rotor
mass eccentricity, magnetic eccentricity and bent rotor deflection. After the
mathematically coherences are described, a numerical example is shown, where
the forced vibrations caused by bent rotor deflection are investigated, for
different control strategies, where the mass matrix, the stiffness matrix and
the damping matrix are influenced by different
control parameters. The aim of the paper is to show the mathematically
coherences and the possibility to influence the vibration behaviour, by different
control strategies to optimize the vibration behaviour of soft mounted
induction motors.
