Abstract

The invention relates to a method and an apparatus of determining a temperature of a rotor (RT) of an electric induction machine (1) comprising the steps of:- determining a set of temperature-independent comparative stator flux saturation saliency angles (CSA) in a reference frame,- determining an actual stator flux saturation saliency angle (ASA) in the reference coordinate frame depending on a machine model (MM) comprising at least one rotor temperature-dependent parameter,- determining a temperature-independent comparative stator flux saturation saliency angle (CSA),- determining a deviation between the actual stator flux saturation saliency angle (ASA) and the temperature-independent comparative stator flux saturation saliency angle (CSA),- determining the rotor temperature (RT) as the temperature which minimizes said deviation.
