The motor itself has a built in gearbox with a worm gear (i will attach a picture). Could it be that they mean the dc motor's shaft's load torque by the 0.55 kg.cm without the gearbox? So with the gearbox it becomes much larger?
I would like to make a project where a dc motor will help the movement of a human arm. The motor will be at the elbow, the stationary part will be attached to the upper arm, and the moving part will be attached to the forearm, so the motor will help to rotate the forearm at the elbow.
I think...
