Modified Dynamic Modeling of Three-Phase Induction Motor in ABC Reference Frame

This paper presents a novel approach to dynamically modeling three-phase induction motors within the ABC reference frame. Induction motors are prevalent in various industrial applications, necessitating accurate models for effective control and optimization. Conventional modeling techniques often overlook key electrical and mechanical dynamics, leading to suboptimal control performance. The proposed model integrates additional elements such as rotor flux dynamics, stator and rotor resistance variations, and saturation effects into the dynamic framework. Utilizing the ABC reference frame aligns the model closely with the motor's physical structure, enhancing fidelity and predictive capabilities. Furthermore, the model accommodates non-linearities and parameter variations inherent in real-world scenarios. This manuscript's primary goal is to offer an induction motor model in the ABC reference frame. With the suggested model, a thorough examination of a three-phase induction motor can be assessed. Utilizing MATLAB R2024a software, analytical analysis and simulation studies will be conducted. The suggested model can be used to test fault diagnostic algorithms for induction machine faults.
