Abstract

This paper deals with a calculation method of eddy current losses and temperature rises at the stator end teeth of hydro generators. It can be used for analysing and evaluating different design variants when optimising the stator core end portion. The calculation method simulates the three‐dimensional local core end field, but uses only a two‐dimensional calculation model. Amongst all the stator teeth it treats the tooth with the highest axial and radial magnetic flux impact. The paper presents a collection of calculation algorithms of the method and provides some results gained for two different stator core end designs.
