Analysing The Impact of Temperature Variation On the Performance of 3-Phase Induction Motor for Industrial Applications

This study investigates the effects of asymmetrical thermal flow in three-phase induction motors, analyzing its impact on motor performance, efficiency, and longevity while proposing strategies for mitigation. The research aims to: Develop a computational model of a three-phase induction motor, simulate and analyze using ANSYS Motor-CAD 2025 R1.1, assess the impact of thermal asymmetry on motor performance and propose effective thermal management solutions. The study focuses on the thermal behavior of induction motors, particularly examining temperature distribution, heat dissipation, and efficiency losses due to asymmetrical thermal flow. It employs numerical simulations and analytical techniques to identify critical thermal zones and evaluate different cooling strategies. The research utilizes Finite Element Analysis (FEA) with ANSYS Motor-CAD 2025 R1.1 to model and simulate heat generation and dissipation in key motor components (stator, rotor, and windings). The simulations are conducted on a Dell Inspiron 5593 with an Intel Core i3-1005G1 CPU, ensuring accurate computational analysis. The study reveals that asymmetrical thermal flow leads to localized overheating, increasing winding resistance, reducing efficiency, and accelerating insulation degradation. Temperature variations of 74.7°C, 76.7°C, 88.7°C, and 86.5°C were recorded in different motor sections, with an acceptable thermal range of 10°C to 40°C. Optimized cooling mechanisms and material selection significantly reduce these effects, enhancing motor efficiency. The findings highlight the importance of effective thermal management in induction motors. Implementing optimized airflow, improved material selection, and enhanced cooling techniques can mitigate thermal imbalances, ensuring improved reliability and operational efficiency of induction motors in industrial application.
