Re: Small Banebots Motor Issue - Lessened torque and smoke

Stall current is 42A, spec'd stall torque is 158 in-lbs, but the safe operating range is 100 in-lbs max. So yes, if you were running these on 20A breakers they should be tripping before these motors stall.

However, the Banebots gearboxes HATE side-loading on the shaft, which could be causing the motors to smoke. Try using the bearing block - also, I'd recommend using two of the 64:1 36mm gearboxes to the lift it to double the safe torque operating range to 200 in-lbs., before additional reduction with sprockets.
