Yes, I am talking about ESC.....with that attitude I'd rather not waste my time explaining!
An Arts graduate, I'd presume?
(apologies, hope you enjoyed it whilst I wasted time at Eng school)
Prior to reading your gormless reply... was kinda curious about it myself whilst on the workbench last night. So out of pure curiousity I pulled out:
-TA04 sitting raised, stationary on a car stand, no shell.
-P2k rebuildable stocker in great condition
-Cyclone ESC (with the exposed FET tabs, not like on new ESCs)
-no cooling fans, breeze etc.
Room temp was 18 degC.
Battery fresh off charger was about 22 degC, everything else at 18.
1) pegged the throttle with a cable tie, at about 1/2. Let it run for about 3 mins. Result:-
2) repeaked the pack. Let everything else cool down to room temp, then pegged it at WOT. Ran for 3 mins, result:-
(Why 3 mins? Only because I was continuously checking the temp and it took about 2 mins for everything to stablise ie temp didn't rise any further.)
For the record, rechecked surrounding temp at the end, it now read 18.5 degC (about 30 mins from when I started).
Heck I know its not the most scientific test (motor not very loaded, its a cold day, Cyclones run cool normally anyway etc etc)... but definitely didn't find any significant basis for the "ESC running hotter" claims.
As an aside... what about airflow?
ie car driving Slower will have Less airflow over the ESC.
Anyhow, rather than all this speculation... what do the ESC MANUFACTURERS say about this??
