Re: CIM Motor Data Sheet/Operating Temperature
It is normal for the CIMs to get very hot after 2 minutes (match length) of heavy use. If you are operating for longer than a match length, they will be very hot, but I've never seen a CIM quit working from getting too hot. In my experience, you can drive a robot the length of a parade route (1/2 mile and 1 battery change) with 1 CIM per drive gearbox and they'll be really hot, but that's about as much as I'd drive them without a break.
When you change your battery, it's a good idea to let your motors cool down a bit before continuing. That's my rule of thumb.
I don't have any numbers to back up the way I do things, I just try to play it safe since I don't have any official data.
