View Full Version : breaking in a new motor

How much run time does it take to break in a new motor. The guy at my LHS said "run at less than half throttle for 2 to 3 packs" but later I realized that he wouldn't know what packs I was using. I have 2 1300s, 2 1500s, 4 3000s and 2 3300s. So 2 to 3 smaller mAh packs would equal 1 higher mAh pack. What would you guys recomment for breaking in a new motor?

Geeze, I think it took about a half-hour or so to break in my Amber. I used two D-cell batts directly attached to the motor leads.
So, I'd say, expect at least a half-hour. Probably 45 mins.
Edit: because I can't spell.

Check this (http://www.misbehavin-rc.com/pit-lane/motor-maintenance/g-motor-maintenance5.asp) out for some help.

Cool thanks, I thought I had read everything on that site, but i must have missed that one. I don't have any 4 cell packs (except for one of my receiver packs, would that work). But I liked the drill idea. I have an 18 volt DeWalt cordless. So I can use that on reverse to break in brushes? Does it matter how fast the drill is? It has 3 speeds and high is pretty fast. Would this be better for the motor since there is not direct current?

Well, it's advantage is that it doesn't put voltage into the motor, and if you keep the motor leads away from eachother, you won't induce any current either.
I tried the drill idea, but it shook too much to be useful. I also tried the rotary tool route since it is faster, but that was even worse. I couldn't even hold onto it.
That's why I used "D" cell batteries. I got a nice 3 volts that way and I didn't have the shaking issues that I did with the drill/rotary tool.
It's still going to take some time, I'd guess the faster you spun it, the less time it would take. But it will still take time.
Since my brushes were already the shape of the comm, I just ran it until all the serrations were gone off the brushes.

So would directly connecting my 4 cell receiver pack be usefull? Or is this just a silly idea?

Should work just fine. Only thing is you may have to recharge it a couple of times. AA cells don't last terribly long. Even unloaded, motors are a fairly heavy draw.

Cool, thanks. :)
