Abstract :
In this paper radial and tangential electromagnetic stresses acting in synchronous machines are expressed as function of known and measurable parameters. Therefore, their values are estimated in case of salient-poles and smooth-poles generators. Finally, the effect of the rotor eccentricity on open circuit and in load condition is evaluated, in order to obtain a more correct evaluation of the unbalanced magnetic pull
