Abstract (en)

[origin: DE19832708A1] A two-pole electric synchronous machine includes a stator and a rotor arranged horizontally in the stator bore, and mounted in two pedestal bearings. Resonance vibrations of the rotor occurring at twice the rotational frequency of the rotor have their amplitudes adjusted to as small a value as possible. The resonance vibrations occurring at twice the rotor rotational frequency are adjusted in amplitude depending on the vertical- eccentric alignment or orientation of the rotor axle (2,21) in the stator bore (6). More specifically, the amplitudes of the double rotor-frequency vibrations are adjusted by a vertical- parallel displacement of the rotor axle (21).
