Brushless motor burnt?
 

I purchased a pre-owned motor, it looks like described, etc. The motor has a little smell to it. I have to put my nose within 1-2 inches of the can to smell anything. It's not a burn smell but it's definitely electrical. Is this normal?

I took the motor apart to clean - the insulation is fine. This is my first motor (first brushless ever) since '91 so bare with me lol. The smell is on my hands as well.

It's a dry sulfuric smell.

Anyone? I think this is a real basic question and answer.

Did you trying running it? So it just has a smell? How are the internals?

Sounds like it got hot at one point.

which may or may not be a huge issue. I got a Thunder Power 17.5 warm, to say the least, I didn't know if it would survive the day..It ran for a full year after that, continuing to "smell" the whole time, until the new owner (local) killed it, I mean he really killed it. (his fault)

The insulating material used to pot the windings can stink. As long as it doesn't smoke, run it. I've got a TP-Power 3674 4-pole that smells like that, and it runs fine.
