This paper presents a lumped parameter thermal network and a hybrid model of a synchronous reluctance motor to predict the temperature of its different parts. The lumped parameter thermal network is developed and its parameters are calculated by simplified analytical correlations. The hybrid model consists of a 2D finite element model of the active part of the machine coupled with a lumped parameters thermal circuit of the end-winding region. A synchronous reluctance machine is used to validate the proposed approaches. The results from the proposed methods are compared with the experimental ones obtained from measurements on a prototype machine. The comparison shows a good agreement among the experimental result, analytical thermal network and hybrid model.
