Original abstract
The aim of this study is to assessed the influence of the unbalalnced magnetic pull on the natural frequencies of the rotor of the generator.The magnetic stiffness of the air gap is obtained as a function of the deflection of the rotor of the generator. This dependence is approximated by a power series. The influence of the unbalanced magnetic pull on the natural frequency of the rotor of the generator is studied by harmonic balance method.

Cílem této práce je posoudit vliv magnetického tahu na vlastní frekvence rotoru generátoru. Byla získáná závislost magnetické tuhosti vzduchové mezery na amplitudě kmitu hřídele. Tato závislost byla aproximována mocninou řadou a tato aproximace byla dále využita při výpočtu vlastních frekvencí rotoru generátoru. Vlastní frekvence rotoru generátoru byly počítány pomocí metody ekvyvalentní linearizace.
