Appropriately modeling core losses distribution within a motor is important for thermal cartography of the motor. This paper proposes a polynomial function approach for modeling the spatial loss distribution within an induction motor, and that takes into account stray losses. Both the finite element method and experimental analysis are used to determine the mathematical functions. These functions are then implemented as user defined functions in a commercial thermal analysis program to represent heat source distribution. Significantly better temperature values at the measured points were obtained with the polynomial function approach versus those obtained under uniform density repartition (UDR) for a 50 HP squirrel cage induction motor
