Cooling fans for Trampa motors

I’ve been running into overheating issues lately kicking in VESC’s motor power limiting on longer trips during sunny days (UK, London).

As a first step designed a meshed motor end, but that had no observable affect on motor temperatures: 20180623_231732

As a second step, designed motor fan, which seems to have solved all issues: 20180623_225421

Appreciate that I’ve not done any rigorous testing, but sharing in case anyone else finds it useful: and


Innovation, nice work.

Higher gearing ratio should do the trick :slight_smile:

Already 13:66 with 203mm wheels :slight_smile:

1:3 isnt alot :slight_smile:
