Re: 2005 Motor Information

I think it was pretty much a lack of understanding.

I played around with the motors, gearboxes, and some sprockets and convinced myself that the reductions I was planning to do to have the FP run our arm will in fact have more than enough torque, with one FP motor, to lift the arm.

Just to make sure I understand: The "stall torque" of a motor is the torque it provides (or the torque it takes to turn it) when the motor is not moving. So if I am to take a motor that is not hooked up to any sort of power source, the torque I apply to force the output shaft to rotate is that motor's "stall torque."

Thus: The reductions on my robot's FP system are such that with a full load (a tetra at the end of the arm) and no power, the system does not move. This means that I am putting no load on my FP motor when my arm is stopped at a 45 degree angle. I am producing no heat! This means that I do not have to worry about overheating my motors, because I have done such a large reduction on my system.

Does this all sound valid?
