TL;DR: In this paper, a simplified thermal model for variable speed self cooled induction motors is proposed and experimentally verified, based on simple equations that are compared with more complex equations well known in literature.
Abstract: In this paper, a simplified thermal model for variable speed self cooled induction motors is proposed and experimentally verified. The thermal model is based on simple equations that are compared with more complex equations well known in literature. The proposed thermal model allows to predict the over temperature in the main parts of the motor, starting from the measured or the estimated losses in the machine. In the paper the description of the thermal model set up is reported in detail. Finally, the model is used to define the correct power derating for a variable speed PWM induction motor drive.
