Abstract
A method for estimating the magnet temperature in an electrical machine carried out by means of an electronic computer involves estimating a value of a total magnetic flux of the electrical machine and estimating a value of a first partial flux, representing a magnetic flux due to a reluctance of the electrical machine. The method also involves the steps of calculating a value of a second partial flux as a function of a difference between said value of the total magnetic flux and said value of the first partial flux and determining a value of a magnet temperature as a function of said value of the second partial flux.
