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...
This paper presents the calculation approach acceptable for evaluation of magnetic pulling tensioning forces acting between the rotor and stator due to rotor eccentricity for choice of electromagnetic bearings for high-speed synchronous electrical machines, permanent magnet machines (PMSM). The aim of this research is to study these forces in no-load mode and in the rated mode. On the basis of the...
