Abstract
Theoretical bases of determination of the electromagnetic forces operating on the windings conductors of the electrical machines and also on the whole on the electrical machine rotor taking into account the influence of the force intensity in the magnetic field of a gap on the ferromagnetic core are considered. On the example of turbogenerator the numeral-field calculation analysis of forces being on conductors in the slots of stator and rotor, analysis of distributing of the magnetic tension tensor in a gap, analysis of the electromagnetic and reactive torques acting on the rotor, analysis of the one-sided magnetic tension forces of the rotor at eccentricity of a gap are conducted. Calculations are conducted under no-load and rated load conditions and if there is only a magnetic field of the stator winding. References 10, table 1, figures 8.
