Re: Small Banebots Motor Issue - Lessened torque and smoke

Team 422 also had issues with the little banebots motor giving up the smoke.

The scenario:
We had an arm that weighed 5 lbs and we estimate its center of mass to be a little over a meter out. It was connected to the banebots 64:1 motor with an additional 9:1 sprocket reduction. We powered it up and it had plenty of torque, it was so fast and strong that it threw the tubes(not our intentions) but when we tried to hold the arm steady at a given point, by providing enough power to the motor to hold it against the gravity of the unloaded arm, we had it holding there for about 30 seconds and out pops the magic smoke.
