Hi people,

just thought that starting a new thread to talk about Brushless...

Has any EP Kakis move to BL or have intentions to???

Please post it here...

ijnek

i have...
smooth operator...

Any cogging problems with you sensored BL? I believe the sensorless BL have got this kind of problem when starting from standstill.... hence slight delay when accelerating.

i'm using novak BL.sensored esc n motor.no cogging encounter.
for sensorless BL,i remember that u can install a 6V receiver pack to overcome tis problem.i have seen it b4...

horniez

i think this new generation BL have lesser of this problem liao...

i tried ijnek's 04r.... very very nice & smooth!!! hehehehehehe...

ijnek

it's not new generation.jus the type...sensored or sensorless...

horniez

but BL also have gone a long way wat...
the first generation have lots of this problem...

just tat after many years & increase in technology...
this cogging problem has also dimished lor...

It's like cars... 20 years ago have honda accord, now also have honda accord... just that the cars got improvement mah...

get wat i mean?

ijnek

not really...
sensorless BL setup still have cogging problem.

horniez

yes... i said diminish... not disappear...
BL nowadays would have cogging, but compared to the yester-years... it've improved lots already...

I really don't know that they mass produce BL for cars in the yesteryears.................

The only brand that i heard of for cars (insane speed run) those days is the Aveox brushless, and this BL is actually meant for EP planes, but modified for use on cars, and it only accepts 10 cells and above!

The cogging problem is still exist in today's sensorless BL as this is the ESC means to locate the polarity of the rotor, and thus turning it. But the problem seems to smoothen out by using sensors to sense the rotor position. The downside however are the bundle of wires that you will have to tuck inside the car chassis.

BL is still veri new to cars.
in yester-years,BL use for planes,heli,boats...but nvr cars...bcos they dun need brakes...

horniez

yes guys...
i did NOT say that cogging is no longer a problem...
i just say that it has diminished (REDUCED)...

from articles that i read about BL, "Brushless motor technology has existed for quite some time..." again... i didn't say only for cars... *sigh*

my point being that BL has been around for couple of years & it has improved over the years with regards to cogging problems...

or my choice of words (yester-years) brought u back to 5 decades ago???

the link below is one of the articles i've read...

brake fade is another problem,but tat applies to cars oni....

horniez

well, i tested out my BL at Giant on sat noon time...

not sure whether it's the Giant's satellite dish or wat,
but i had glitching problems... car going crazy at far side of the track...

couldn't be anything else as I only changed to BL... nothing else had changed... hmmmm...

ijnek

find another tack n try again...mab bestmart or pasir gudang or even jus a basketball track...
