ABSTRACT:
A method for non-intrusive determination of an internal temperature of a given area of an electrical machine stator, comprises obtaining a temperature gradient between an internal wall of the stator and an external wall of the stator, obtaining temperature measurements at locations on the external wall of the stator, and using the temperature gradient and the external temperature measurements to extrapolate corresponding internal temperatures of the stator.
