Default run in a used motor

hi i am new to electrics, i heard someone at the track talk about dipping the motor in water and running it...

well i have already ran my 540sport tuned motor in my car for about 1 hour.... is there any benifit if i do the dipping technique now?

i was told basically dipp the motor in water with 4.8v power for about 2-3minutes... anything else?


thanks for any advice

I am also a newb, unfamiliar w/ the dipping technique.

But I think if you do not know what you are doing, water is not the best thing for motors. I do not think anything anything will short circuit, but certainly, rusting maybe a factor.

I run in my motor at 2.4 volts for 3-5 minutes. Works well enough.

I clean my motors after every meeting with water and a very,very small drop of washing up liquid for 2-3 minutes with short burst of throttle(pinion off).Once dry i re oil bearings and left ready for next meeting

Thumbs down water and motors?????

Forget the water and use a few bursts of motor spray after every run to stay fast and prolong the life of your brushes between comm cuts!!

water will not cause them to rust in any way.. it works on the old closed mabuchi style motors.. the water puts a load on the armature, and helps seat the brushes.. As long as you spray it out and lube it again, it will not rust...

My point exactly, if you don't know what you are doing, rusting metal components in a motor is easy. Like using cold water and leaving to dry etc. Proper lubing and motor spraying to remove moisture is essential.

the airplane guys break in their motors this way. you have to use a battery pack and it wont short out. the airplane motors have closed endbells.

Basically,running in the motor in the water will seat in the brushes more quickly then normal break in.As the water act as a load and it keeps your motor cool during break in.And thus higher voltage can be used,eg 4.8Vs.Also keeps arching which is bad for the comm.Then in between breakin,you should frequently check the state of the brushes by looking thruough the openings against some light.When the brushes are seated fully or almost fully,you're done.

Just be sure to dry out the motor and oil the bushings.

the best suggestion i can offer is just leave it the brushes will naturaly seat them selves over time run in makes it easy to damage just a few shots with motor spray on the comm and relube the bearings also comm drops are handy (i use zubaks) i found most others arent anything special

Default Ice Ice

Get some reallllllly cold water with ice in it so ice water

Conect the 540 motor straight upto a battery pack.. and let it rev/run in the icey water for 15 mins, pull it out spray the motor with motor spray and re-lube the bushings

ANother trick ive heard is running the motors in Brasso,(Brass Polish) but ive never seen it..

I've also heard of the brasso method.I've heard of this formula before,using 10 part Benzine(The same alcohol type substain),1 part brasso and 1 part heavy oil(maybe your engine oil and I mean for your full size car),cause benzine is very flamable.So the oil is to supress the combustion.

Then after the run in,drop 1 drop of olive oil to your comm.Yes! Olive oil that your mama use to cook food with...

I've never tried this method before,but heard its very good.
