thermal management

I am conceptually designing an outer-rotor, gearless magnetic hub-drive wheel for a surface rover on Venus. To avoid the Curie temperature limitations of permanent magnets at 460°C (733 K), the system relies purely on an AC induction motor topology. The primary coils (stator) are locked to a...

I keep running into the same tension on industrial control enclosures and would like to hear how others approach it. For IP-rated (sealed) cabinets, you can't just vent to ambient, but the gear inside — VFDs, power supplies, PLCs, contactors — all dump heat into a closed box. On a few jobs...
