Sažetak
The paper deals with electromagnetic analysis of the hydrogenerator with fractional winding. General purpose FEM based software and its built in automation support were used to automate the analysis. Generator has been modeled as a true magnetic symmetry element and not by one or two pole pitches as it has been done in the past. The no-load characteristic, reactances, short circuit field current and rated load field current have been determined. The results have been compared to those acquired by classical, analytical methods and measurements in case of one real generator. FEM based analysis also shows the difference in magnetic flux distribution in rotor poles for different positions of the rotor.
