cheap esc

[jshalcott]

i'm going to use a cheap esc. would a 40 amp esc be ok for a 12-18 volt motor

That depends specifically on the motor and the application.

Check the motor datasheet and see what the current draw is on it. If you are lucky, the datasheet will give a chart that compares torque vs current vs voltage.

From experience, 40A will probably be fine.

Try not to use motors above 12V because finding good/small batteries starts to become difficult.

thanks, the 50 amp one is a little bit more money so i think i'll go with that just to be safe.
thanks

Remember that everyone doesnt know what an esc is, as a side note

If someone doesn't know what it is, they can't really help him with his question, so who cares?

Well, obviously the poster of the question will care. I am just saying, that lots more people might input if they knew what an esc was.

I have never come across this before, in my 'many' years of studing the subject. Therefore it is just a small, albeit helpful warning.

Good point.  I think robot types are less likely to know the term than RC junkies.

and still nobody has defined esc...

esc = electronic speed control

esc = electronic speed control

But it's actually controller, I will let you off.
