AE2 esc,punk,and 2 35t motors

[stanmondz]

the motor limit is 19T, whats the formula for finding out weather a esc can safely run what turn motors? is it 35 divided by 2?= 17.5t

i got 35t's in it now and really like em,but id rather throw the 45t's in it if the 35s will kill the esc.

im running 2s packs right now if that matters. id like to go 3s.
i got the esc,motors and a few small 2s packs, and score the dig cheap,and gonna get the hack for my gt3b
the money aint there for dual esc's & 3s right now.

if the ae-2 is like a sidewinder you shouldnt have any problems.

[stanmondz]

with the 35's?

i could pull the sidewinder out of my ax10,and put the ae2 in its place i guess. from what i can find,its also 19t limit

You can't really just do simple math to find the limit, dual 35T is starting to push it for a single ESC unless it's a higher end one (Mamba Max Pro, BR-XL).
Check temps and don't try to power out of too much and you should be OK for now.

I ran dual 35T & a servo dig on an old Mamba Max, no issues.

so is the formula for motor turns 35T divided by 2?. if so that exceeds the 19T motor rating.

if i swapped to the 45T motors,that would be for sure safe for the esc?

I think your over thinking this, if the specs on the AE-2 is like a Sidewinder you can run the 2 35's on it. You are running the motors in parallel so you don't have to split anything. I ran a Sidewinder setup with the 35's and a punk dig on my Berg for a long time on 3S and had no problems.

[stanmondz]

yeah, it has the same brushed reverse motor limit as the sidewinder. ill only be running 2s

I ran 35t's on 3s with a sidewinder with no problems an The pinions that came with them were 21t pinions.. an no problems... You will be good on 3s.

[stanmondz]

cool. id still like to know how to figure out what turn numbers are safe and whats not though,for future knowledge

The rough way is for your case the 35/2 but in reality that doesn't hold true especially when you get into the lower turn motors and then factor in all the different variances between motors and if they are hand wound or not, ect...

In your case you should be just fine since at one time I ran 2 brood hand wound 30t's on 3s on a sidewinder, sure it got fairly warm but it was fine so if you are just using 2s you will be fine

i can pull the fan off the outcry esc thats in it now and throw it on the sidewinder if i have to

If your just crawl'n with this , say on a 450 MAH or 800 MAH battery you wouldn't have to worry about it overheating and running a fan.
If you trying to run a 4000 MAH or around that number (trail running) you will overheat the motors before anything else.
The speedo will handle down to a 15 turn motor (at least, maybe lower) when you convert the rating limit that Castle has.
P.S. This should be in the electronics section.

While googling my question i found this thread.

i still dont really understand how to safely calculate using two motors.

my plan is going onto a big truck. 1/6 F350. big heavy metal job. its already got a good 5-10kg under its belt and its gonna get heavier.

i just ordered a pair of 48p 16t pinion gears and a dual motor mount for the Axial transmission.
from there it will run through a 1:1 transfer case and then out to each AR60 axle.

i currently have a double 16turn motor(28tooth 48p pinion) running on the AE2. with no issues so far, on a 2s2p 20c lipo.

i was considering getting a second wraith motor (20t) but have since learnt that running two in parallel effectively halves the load at the ESC making it
a theoretical 10turn motor, which apparently is too low.

now, the truck being so heavy, its not going to be a racer. its a trail truck. low speed, climbing. probably a fair amount of full throttle mud runs, climbs, etc though.


so with all that said what will happen to the esc if i do try to run a 10t motor(2x20t) will it just get hot like an amplifier does with not enough impedance??

i can very easily implement a fan. or, i can just purchase a pair of higher turn motors, i was just trying to not sacrifice too much top end if i could help it.

TIA for any help on this matter. i would mostly just like to learn a little more about how and why motor turns are important to the esc.
