Simulation of Rotor Bar Breakage in AC Induction Motors

This document presents a simulation framework for analyzing rotor bar breakage in AC induction motors. The implementation typically involves MATLAB/Simulink models where motor parameters can be configured through script-based initialization files. Spectral analysis of simulation results is performed using FFT algorithms to identify characteristic frequency components associated with bar breakages. The code architecture allows for investigating different breakage types, including rotor slot breaks and end-ring fractures, by modifying resistance parameters in the rotor circuit model. Additional simulation modules can be integrated, such as thermal analysis using finite element methods and structural simulation through ANSYS co-simulation interfaces. The framework supports parameter sweep studies to analyze breakage progression patterns, with results exportable to CSV format for further statistical processing. These research findings can be applied to practical manufacturing processes, helping improve operational efficiency and reliability of induction motors through predictive maintenance algorithms.
