Hi,

I'm breaking in my motors following the advice found in the FAQ, using a 3V battery. It's now sparking inside the motors. Is it a normal process or am I just destroying them?

Thanks

Um.... sparkling? or sparking?

Sparking, sorry

If you're going to reply, answer the guys question. Don't make fun of their spelling!!!

You do sometimes get sparking indside the motors.

Well, you didn't answer the question either...

Yes, I've noticed some sparking inside my motors when I was breaking them in too, especially between the brushes and the shaft. This shouldn't be a problem, my motors ran fine afterwards.[sm=thumbs_up.gif]

Normal.

Arching is normal, just depends on how much. Make sure there isn't oil on the comm and the power supply is clean. Most of these motors are RTR, meaning the brushes are curved to fit the commutator. I would be more worried about breaking in the gearbox first because these motors are stock and do not run at a high RPM all the time like say a slot car motor would.

I know because I used to re-wind motors that I raced, twist the comm to change timing and even balanced them too.

Happy CN12?

All right thanks for the infos.

The first motor ran fine but the second one just won't start. The battery is ok, wires connection/soldering too. The part going into the gearboxes is harder to spin. Another piece of junk?

Apologies to MyRcFun for placing an offtopic question, just wanted to know the difference between sparkling and sparking, cannot find the verb sparking, I always get redirected to spark.
Thanks
Jose

Sparkling is to Sparkle as Sparking is to Spark

To Sparkle is to issue or redirect light as if from a spark (i.e a sparkling diamond)

A Spark is an incandesent glowing particle (in this case thrown from within MyRcFuns motor)

I hope that helps more than it confuses

According to Webster's both are nouns.

sparkling: Flash or Gleam or to perform brilliantly.

spark: a small particle of a burning substance or a hot glowing particle struck from a mass like steel on flint.

Tanks for the responses
My confusion came from a **** online thesaurus that says:

spar·kle (spärkl)
v. spar·kled, spar·kling, spar·kles
v.intr.
1. To give off sparks.
2. To give off or reflect flashes of light; glitter. See Synonyms at flash

Later I've done a search through the Oxford thesaurus and it gave the correct definition:

sparkle
• verb 1 shine brightly with flashes of light. 2 be vivacious and witty. 3 (sparkling) (of drink) effervescent.
• noun 1 a glittering flash of light. 2 vivacity and wit.

Thank you fellow tankers
Regards

I thought the whole point of the process was to avoid arching?
