Thermal properties on high fill factor electrical windings: Infiltrated vs non infiltarted

På svenska

Author

Summary, in English

This paper presents a comparison of the

thermal properties between infiltrated and non-infiltrated

copper windings. The focus is on thermal conductivity in the

radial direction on the winding. The samples have a fill factor

above 65 % due to the manufacturing method of the samples.

Samples are produced and measured with the transient plane

source technique and then compared to FEM simulations and

the Hashin and Shtrikman approximation. The results show a

considerable difference between a non-infiltrated and an

infiltrated winding, as well as a good agreement between

measurements, FEM simulations and the Hashin and

Shtrikman approximation
