Analyzing the effect of asymmetrical thermal flow in three phase induction motor

Abstract Because of their dependability and effectiveness, three-phase induction motors are frequently utilized in industrial settings. They are susceptible to asymmetrical thermal flow, though, which can have a negative impact on longevity, performance, and efficiency. Even though this problem is common, its precise thermal impact and mitigation techniques are frequently ignored in the literature that is currently available. Using ANSYS Motor-CAD 2025 R1.1, this study fills this gap by creating and analysing a computational model of a three-phase induction motor in order to assess the impact of thermal asymmetry and provide practical thermal management options. In order to model heat generation and dissipation in crucial motor components including the stator, rotor, and windings under asymmetrical conditions, the study uses finite element analysis. The findings indicate that thermal imbalances cause higher winding resistance, decreased efficiency, localized overheating, and hastened insulation degradation. With observed temperature changes of 74.7 °C, 76.7 °C, 88.7 °C, and 86.5 °C, the permissible thermal range of 10 °C to 40 °C was greatly exceeded. The suggested tactics, which include improved cooling, redesigned airflow, and material advancements, show a great deal of promise in reducing these impacts. This research adds to the continuous endeavours to improve the energy efficiency and thermal dependability of induction motors in actual industrial settings.
