Which Capacitor

[DirkDigler]

I bought a package of Capacitors at Radio Shack.
It came with 80 of them.
Problem is.....Not sure which ones to use on an Axiom lathe motor.
They all have numbers on them.....1-30

Can running the wrong caps on the motors damage anything?

do you need cap. on a lathe motor? i have a 60t and el cheapo tamiya kit esc, no cap.'s and havnt noticed any problems, also using the nomadio

I wouldn't have asked the question if I felt that they were not needed.

True, I have minimal glitching when running the motors without caps, however, there is sometimes a glitch, which may occur at precisely the wrong time, during a comp, etc.

i wasnt so much questioning wether you need them in your case, i was lazy when i soldered the leads to the motor and havnt had any glitchs so i never bothered to go back and run caps. i'll have to try my futaba to see how much of a dif the nomadio makes

Dirk I use these capacitors ( http://www.radioshack.com/product/i...kw=capacitors&kw=capacitors&parentPage=search ) on my lathes, I didn't notice any numbering of 1-30 on them, just a 0.1uf. Not knowing anything about capacitors awhile back I put on a wrong kind it got really really hot and popped. I'm guessing the worse that could happen is it will pop or be overkill (overkill is not a bad thing). the small caps we use shouldn't backfeed to ur esc and damage it.

hope that helps

if your 1-30 matches up with that, then you have a bunch of 13pF caps, they may be a bit small. are they definitely 1-30 and not just 130?

here's another site:

from a circuit noise perspective, the larger the capacitor value, the lower the frequency of noise it is generally used to protect against. a really, really big cap can smooth out power line voltage fluctuations on the 110V lines coming into your house (well, 220V). a really small cap will smooth out high frequency noise. the wrong value of a cap will start filtering out that 4kHz frequncy coming out of your ESC (or 2.4kHz or whatever it is running at). you really can't damage anything with incorrect cap values on your motors, just induce more glitching than you are trying to eliminate. i think i'm using somewhere around 0.1uF on my Integy 55T motors with a Moped ESC. i can verify when i get back home.

0.1 microfarad are the ones you want.
