How to achieve slot fill factors higher than 99% with trickle impregnation for 800V e-drive hairpin stators?
As the current trend is moving away from conventional (Internal Combustion Engines) power train systems to fully or hybrid electric systems, there is a strong demand and need for high life time performance as well as high efficient 48-Volt, 400-Volt and 800-Volt e-drive platforms.
This means that high partial discharge interception voltage (PDIV) resistance values and high filling grades are required when impregnating especially 800-Volt hairpin stators. To achieve slot fill factors higher than 99% during high series production process know-how, development and process control are absolutely crucial and thus longer lifetime expectations of next generation electric e-Drive machines especially with the outlook into 800V platforms can be reached.
During our presentation "How to achieve slot fill factors higher than 99% with trickle impregnation for 800V e-drive hairpin stators?" we will inform you about the advantages and developments in trickle-varnish impregnation technology.
