Abstract
This article deals with usage of permanent magnets, especially their behaviour at different temperatures. In the introduction one possible application is described briefly. It is the usage in the synchronous machine with a rotor whose permanent magnets are located inside the rotor. There is almost always an increase in temperature inside the machine and thus it is important to know the characteristic curve of the momentum decrease with temperature. Using permanent magnets on the basis of rare earth acceptable results can be calculated. The article deals with several kinds of these magnets. Calculations were done using FEM. The results of the solution are discussed in the conclusion.
