This paper presents the method of rotor magnetic pulling tensioning force calculation, caused by the static radial rotor eccentricity. The method is applied to calculate the total force acting on the rotor of high-speed permanent magnet (PM) synchronous machine (PMSM). The calculations are based on 2D simulation of magnetic field distribution in the active part of the machine, taking into account the saturation of the magnetic circuit and the spatial harmonics of the air gap magnetic flux in the no-load mode and in the rated mode.
