hey all


some guys here in croatia put small coolers like on computer graphic card...smal fan,smaller than fan on processor...


they connected it directly to 7.2v battery and said that it works unbelivable


they said they run corally 17t motor with ratio 6.5 and it burned out after 1 battery


then they put that little fan and make even smaller ratio...5.8 and drove 5 batts and nothing...


is that possible?


please write down yr opinnions...


regards to zoomer

Some fellas are trying out Schottkys between the 3 poles on the armature now...



Yeah you need a 5V fan to give good air speed. Blow it onto the brushes end of the motor.


But I'm finding it very hard to buy 5V fans at a decent priceeg <$20; I bought mine off a friend (thanks Cookie!!) who posted in a couple.


12V 30-40mm fans are cheap, cheaper if you yank them off computer accessories but 5V is not as common in PC use.

SIB do motors with the diodes on the 3 poles already. they use a MVP as the base motor. the motor does actually run cooler though the problem is the diodes have a nasty tendancy of falling off and ususally a peak revs. a few of the guys a precc have run them in the past.

Yeah, everyone so far has been only "adding" them onto a already-manufactured motor. But Big Jim is doing it to the armature blank *before* he handwinds them, they're not just tacked onto the top.


btw adding them to STOCK motors is illegal...
only legal on mods.

Hey all,



I have just purchased two magnetic mayhem moors and a super rooster esc
for my txt 1. Being a reversable esc I cant use schotty diodes, so for
cooling would you just suggest the use of fans ?



I have seen heat sinks avaiable for the electric motors, how effective would these be ?



regards
