Testing with active cooling & lubrication system
With this infrastructure we can test & evaluate several novel cooling/sealing & lubrication concepts in powertrains. Furthermore, we offer flexible oil & water&glycol circuits which can be used to test & evaluate several novel cooling & lubrication architectures for your powertrains or components (motor(s), gearbox, inverter, etc.).

Feasibility study of oil jet cooling
This is a slow motion video of a oil jet impinging to a motor coil embedded in a transparent motor version of an industrial prototype. Several challenges have been identified wrt oil jet cooling:
- oil jets are impinging the coils in an uncertain way (e.g. sometimes angled and not on the location from the design phase)
- oil jets are splashing in an uncertain way (e.g. multiple splashing jets)
- the oil splash & not splashing situation can sudden change due to slight oil temperature; oil flow variations
Furthermore, the oil will enter more/less into the air gap leading to high friction losses which is another challenge to solve. Apart from this feasibility study, the thermal performance & power density gain (~50%) vs. a water jacket cooled industrial motor have been studied.
