High Performance Motors
 

So I've already burnt out a Lonex A1 in under a week. I thought it was just a lemon so I bought another, and this one is about to die too.

My current setup is a M120 spring, standard ratio gears, Gate MERF 3.2 and is powered by a 11.1V 25C Li-Po.

Does anyone run a similar setup and has a motor that hasn't burned out?

There's no way your motor should be burning out that fast. Your setup is pretty standard for most AEG's.

Maybe your motor is working too hard to pull the spring, have you checked your shimming?

I'd say your shimming is way too tight or you're electrical system is causing too much resistance. That motor will pull up to a M140 without a problem with standard ratio gears.

The gun was working with no problems using just the stock motor. I've double checked the shimming and wiring and they both seem fine to me. A lot of black residue comes off the motor brushes, and I've never seen that with any other motor.

I'm just looking for other comparable motors that I could try.

shs motors are pretty good. but I have 2 lonex motors into 20k rounds each now and no issues.

Seems obvious. Go back to using the stock motor.

Try and get these when they are back in stock:

They always get OOS REALLY fast though.

ChaoLi, Eagle Force, Tienly, KWA (surprisingly)
third time I've heard of a lonex motor wearing through brushes fast

Other source, but again oos.

Some of the guys on asm have used the motor from dx.com and said its a pretty good one. It's a cheap acm neo one. If nothing else if it burns up you can use the can to make a frankentorque motor.

If you're seeing more than normal of the carbon dust, then you're having too much resistance in your system. The carbon dust is caused by amps resistance, and too much amps will cause more burning which cause more carbon dust. Make sure your bevel gear is shimmed correctly to the pinion gear, as most people shim that gear incorrectly. Then check your battery and connectors. Best way to check for electrical resistance is to pull out the gearbox and install the pistol grip and motor. Plug in the battery and shoot in full auto. Feel around the wires and see what is getting hot. Then you'll have an idea on what could be the cause. The MOSFET could also be the caused too.

HKGhost, is that due to the AB feature?
I have semi related question i think. I have a buil with an m90 13:1 gears a swissed piston and pom head. Rest is all stock cyma crap.
Running the merf3.2, low resistance silver coated cooper wire and an 11.1 25c (30amp) and i notice if i shoot off a cplhundred rounds (and mp5 highcap) the grip gets prety hot. Lotta the shooting in semi. Shim job is good all round pushing round 30rps (still have to test for an accurate number).
Is this heat somewhat normal on a setup like this?
Should i expect to burn out a motor prety fast due to this heat build up?

Yes, the AB feature will wear out your motor faster than without it. Because of the AB, your motor will get really hot really fast in either a high speed or high FPS setup. I personally always disable or remove the AB feature when I can.

But if you have a really high quality motor, like an eagle force EF1300, they're much more reliable at high temps. Every time I bring the 249 out that grip damn near burns my hand off after laying down some really heavy fire, other than the comm turning pitch black from the arcing, the motors still in great condition after 3 years

I'll double check the bevel - pinion shimming. Since I didn't have this issue with the original motor, is it possible that the pinion gear isn't meshing well with the bevel gear due to it's shape? I'm running Modify gears, which meshed perfectly with TM, CA and Modify pinions, but the Lonex pinion seems to have teeth that are a bit thicker and that part seems to wear to become thinner quite quickly.

When did you buy the Lonex motor?
