Natural frequencies as a function of power were determined using a finite element model. Two operating conditions were investigated: operation with a resistive electrical load and operation synchronized to an electrical utility grid. The influence of certain drive train components on frequencies and mode shapes is shown. An approximate method for obtaining drive train natural frequencies is presented.
