Field distribution in stator core end packages of hydropower generators

Abstract [en]

Hydropower has during the last century been known for its high reliability and efficiency. To refine and develop the technology has kept engineers and researchers busy during most of the 20th century and is still a subject of interest. With a lot of different companies involved, widely spread around the world, different design characteristics exists. A matter where opinions of designers and engineers can differ is what design action to use for reduction of the end heating, caused by the axial magnetic flux.

In this thesis the two most common design actions, stepping of the stator core end and reduction of the rotor magnetic length are investigated. The results shows that both of the design features provides a significant effect of about the same reduction.
