ANALYSIS AND LOCALIZATION OF LOSSES IN AN INDUCTION MACHINE USING A CALORIMETRIC METHOD

Abstract In this paper we determine the loss distribution in a 11 kW, fan-cooled, slip-ring, induction machine. We use a simple thermal model which splits the machine into elementary blocks. The parameters of this model are determined by temperature measurements yielded during typical tests. We then use our model to analyse and localize the losses under several operating conditions.
