What can I do to prevent a CIM motor from overheating? It got so hot I burnt my hand on it. Also what would be good for cooling it?
am-2865 exists? I’m not a mech person, I just spend too much time looking at vendor websites. You can also use canned air upside down to cool it off, but that’s a short term fix. Hope this helps!
How is the motor being used? They’re pretty resilient, if it’s overheating it’s typically an unsuitable use case for the motor.
CIM motors are cooled with time, maybe a large fan during driver practice. If you need mid-match cooling, something is wrong with your application or control methodology.
We were running them on our drivetrain for 20-30 minutes straight. I think we just ran them too long for drive practice, but I don’t want to run into the issue at a comp.
I’ve seen teams also spray canned air upside down to cool CIM motors after a match
That’s very normal for driver practice, you are unlikely to run into that issue at comp.
We usually tipped the 'bot on its side and pointed some blower fans at the motors while getting snacks or doing whatever.
I wouldn’t waste canned air “freeze spray” in this situation, and if you’re not careful you can damage the motors doing that.

The most important question here is what are you doing with it?
Is it being stalled for a long time?
Is it getting hot under long use?
Okay thank you. I was a bit concerned about safety because I burnt my hand on the motor and there was a strong smell of smoke. Meanwhile I could run our FTC bot and the battery would die before the motors ever get hot lol.
Yeah if you smell them they are probably a little damaged, could be some compounding issues but 20-30 minutes of solid driver practice (say, 3-4 batteries worth) should make CIMs uncomfortably hot.
