Re: Temperature Shutoff on Denso Motors?
Yes, the Denso window motors have temperature cutoffs inside. This is definitely what is happening based on your description of the failure mode. Heatsinks and fans would help, but other than that there is not much else you can do. If they run for at least 5 minutes or so, you should be alright, given that they can cool down between matches. Make sure that everything is calibrated (trimmed) so that the motors are not stalling when the bot is just sitting there.
