Default Tamiya Silver Can Motor Break-in

I'm sure this topic has been discussed somewhere, if so, please post the link(s).

What are the preferred ways to break in the silver can motors?

I'm a novice RC-er, but a newbie to Tamiya cars.

What's a good way to break in the motors so they are fast, but I'd also like them to last, and not have a high risk of ruining the motor if I mess up (I've heard water dipping is great but there are risks).

I've heard the Johnson (matte finish) motors are generally faster than the Mabuchi (shiny) motors. Is this true?

Any other advice would be much appreciated.

Thanks.

Well if ya don't want to dip it... your other option would be to break it in at say 1V for 30 minutes... The low voltage will prevent scoring of the comm and polish it up abit.

I think the Johnson 540 motors are the fastest.I think the water method is the easiest and best way to break-in a silver 540.

Can you offer up some details on the water break in?

Fully immerse or just the brushes?

No load or attach a small fan blade?

How long, what voltage, and any other details would be appreciated.

Thanks.

Hey dude if u aint comfortable with the dip method. THen try this. Get some brasso or silvo (brass polish or silver polish) apply it to a cotton bud and run it allong the comm end. use a decent amount bud dont over kill. you should apply it with about 5volts connected to the motor (4cells) for about 10mins after wards spray it down electric motor spray.

P.S. apply some lube to the bushings before you start anything so u get a clean smooth spinning motor

I take mine out of the box, Make sure its a 540-J motor. No Oil, No Comm drops and run the crap outta it. When the comm gets gunked up I use a dentist tool to clean out the segments and water dip for a few seconds to get the comm polished up. After about 5 or 6 battery packs I start oiling the bushings. Mine arn't ballistic, but they are consistantly pretty fast. When they get really fast you better start breaking in a new one, b/c they are almost fried. I had one pull stock cars down the straight for a couple practice laps and half a heat before it went up in smoke. Also keep an eye on the tempeture of your motor, don't get it above 220 degrees I believe that is when the magnets start fading.

Thanks for the replies.

Groffball, when you say "water dip it for a few seconds", does this mean with a low voltage power source applied? Is the entire motor submersed, or just the end with the brushes? I'm not trying to be nitpicky, just don't want to make a mistake and do something stupid.

Thanks again.

Thanks for the link. Seeing it all in a magazine article somehow makes water dipping seem more reasonable. It just sounded strange when I first heard about it.

Thanks again.

sorry i know this is a old post but according to our dynos, water diping kills the motor, Dimo has the right way, you even gain 2 000 rpm that way, from 17 000 to 19 000 sometimes even 21 000rpm and you get a reliable motor, just solder a capacitor to the back of the motor

You don't need any capacitors, they are inside the motor already. Pull an old motor apart and check for yourself.

Slave motor run in is the best as its the least risky, but I must say brasso does certainly make the motor faster as well. I have water dipped many motors before, but really it can be a pretty risky exercise as it can wear the brushes down fast.

Depending on the individual motor, water dipping may only make it slower too, as wearing the brushes down, takes away brush tension.
