摘要：

The article deals with investigation of elastic modulus of laminated rotor core. Elastic modulus influences rotor core stiffness and therefore this characteristic is important for dynamic behavior of whole rotor. In article is described numerical and experimental modal analysis natural frequencies determination. Numerical analysis includes FEM modeling with material properties adjusting. The results of calculation were compared with measurement of natural frequencies experimental modal analysis. Elastic modulus in FEM model was adjusted with respect to modal measurements results. The obtained value of elastic modulus will be used during design process in critical speed calculation of the same rotor type.
