Polskie osiągnięcia badawcze nad naciągami magnetycznymi w maszynach elektrycznych

In this work the main research achievements in Poland on radial unbalanced magnetic pull of electrical machines with circular symmetry are presented. Analytical calculations methods of magnetic pull, given by polish researchers, with respect of elastic rotor properties are presented. The components of radial magnetic pull in two-pole machines are calculated. The achievements contained in doctoral thesis and journal publications are presented. Applications of results of magnetic pull for diagnostic of electrical machines are given.
