Interesting. You could design a robot arm where most of the surface can transmit and radiate heat away from the motors.
PS: Oh I just found out the design I’m thinking of is “frameless dc motor” or servo so you can route cables internally and have aluminum tubes on the outside for heat transport (“When high temperatures are a concern, the machine structure can provide effective heatsinking”). And now that I know the name they are actually not that expensive on aliexpress! Something like this as a servo with CAN and 48V connection and flanges to directly attach lightweight ~15cm tubes would make building a robot arm pretty easy! EDIT: Ok basically you’d just need a lathe to make a housing with flange and to fit a bearing.
