摘要

The equivalent thermal conductivity of insulating materials for a high voltage bar in slots of electrical machines is calculated using the finite element method. This allows the use of much coarser meshes with an equivalent thermal conductivity k_e, without accuracy loss in the hot spot temperature calculation. It is shown the dependency of k_e value on the equivalent mesh used. Some considerations are also presented on the heat flux finite element calculation.
