This paper deals with finite element calculation of the vibrations of magnetic origin in two-speed, large power, synchronous motor. Prediction of such vibrations are very important in understanding vibration phenomena of electrical machines. In configuration for lower rotational speed pole numbers of magnetic field and numbers of excited poles of field-winding are not equal. Because of non symmetrical armature and field windings the only one way of investigation is finite element (FE) modeling. Simulation are done for nominal load, for two different rotational rotor speeds: n=500 rpm (2p=12) and n=600 rpm (2p=10), and corresponding nominal active powers: P=600 kW and 1050 kW. The target of application of discussed analysis is the vibration behavior of the machine.
