description: The objective of the thesis is to develop a methodology for calculating the critical rotational frequencies of an induction motor rotor in a three-dimensional setting, using the example of the DAZO-500-0.69-750U1 induction motor. The work is dedicated to calculating the critical rotational frequencies of the DAZO-500-0.69-750U1 induction motor rotor on compliant bearing supports. To achieve this objective, a modal analysis was conducted in the Ansys Workbench software using two methods: 1) Calculation using the Spring connection element as a compliant support. 2) Calculation using the Rotor Dynamics module and Bearings connection element as a compliant support. The results obtained from the three-dimensional setup were compared with the results obtained using the Rayleigh energy method. During the study, it was found that both proposed three-dimensional calcula-tion methods provide acceptable accuracy; however, the calculation using the Rotor Dynamics module demonstrated higher accuracy. The developed methodology will enhance the calculation of critical rotational frequencies for various induction motor rotor designs.
