Abstract
The paper deals with a method of reducing the unbalanced magnetic pull for large synchronous hydro generators, in case of rotor eccentricity and/or shape deviation of the rotor and stator. The method is based on a dedicated data acquisition system and virtual instruments developed in LabVIEW environment. Experimental results are presented for a 186 MVA and 500 RPM vertical synchronous hydro generator. The method of magnetic centring was applied successfully on 30 high power electrical machines from industrial environment in Romania.
