Motors getting hot while robot immobile
Posted: Tue Mar 09, 2021 8:12 am
Hi,
I just opened our robot (which was turned on but immobile for several hours), and realized that all 4 motors are quite hot (it's possible to touch them, but not for a long time).
There was no slope (the robot was in our office).
We use velocity control (so we were sending at 10Hz a command to set velocity to 0).
Do you have an idea why the 2 roboclaws (2x60A) are delivering so much power to the motors when the robot is not moving (and not on a slope).
Is it possible that it is due to some "small" oscillations of the motors around the "reference" position?
If so, is there a way to reduce those oscillations?
If not, what else could explain that the DC motors get so hot?
Thanks a lot in advance
Best regards
Felix
