In order to predict the lateral rotordynamics of a high-speed induction motor, an optimization procedure is used for identifying the dynamic behavior of the magnetic core made of a lamination stack, tie rods, and short-circuit rods. Modal parameters predicted by a finite-element model based on beam elements and measured on induction motors are included in modal error functions contained in a functional...
In order to predict the rotordynamics of a high speed induction motor in bending, an optimization procedure is proposed for identifying the constitutive properties especially those of the magnetic core made of lamination stack, tie rods, short-circuiting rods, etc. Modal parameters predicted by a finite element model based mainly on beam elements, and measured on an induction motor are included in...
