Thermal Regime of Induction Motors After Rewinding for Other Characteristics Than Those Established by Design

This paper explores alterations in the thermal behavior of rewound induction motors with the aim of achieving functional characteristics different from those initially established during the design process. Through the utilization of Motor-CAD software, the distribution of temperatures within the induction motor structure is analyzed. It is revealed that when rewinding is performed to attain alternative functional characteristics while maintaining the required magnetic field strength, induction motor forces, and current density, the resulting thermal regime differs significantly from the reference version. This divergence can profoundly impact the motor’s operational lifespan.
