Re: smoking drill motors?

when you ran the motors did you use Victors and the 40 amp breakers, or did you connect them right to the battery to test them?

also, were you doing any machining, fileing, drilling on the bot or drivetrain with the motors present?

its possible you got metal chips into the motors

also, were the motors loaded down or spinning freely? if your drivetrain is binding up, and you didnt put breakers in the circuit, then yes, you can smoke them in a few seconds connected straight to the battery if they are stalled, or can just barely turn.

I have seen motors throw their commutators and have the brushes jam (defective motor)

the fact that you said 'motorS' is disturbing - I doubt you would get two defective motors - if more than one smoked its most likely something you did to them.

OK, one stupid question: you do know these motors are 12DC, right? you didnt hook them up to two batteries in series, or plug the motors into a wall outlet, did you?

DID YOU? :c)
