I'm a communication engineer so my knowledge about robotics is very little.
I know the basic formula of torque T=mgL
in my project I have 2 arms & 2 motors
i used a torque calculator online and it came out with a very high torque a s a result which I didn't even found in the market!
So the higher torque motor should have a torque of 580 Kg cm which is equal to about 60 Nm
I never found a stepper motor with such a great torque.
i read somewhere else in Quora that to lift a weight of 50 KG you need only 1NM so how come my 10 KG load requires that high torque?
so is there is something wrong with my calculations? and what is the holding torque? is it the same one I'm calculating or it has another relation.
Note: I'm not concerned much about torque resulted from angular acceleration as I want a constant rotational speed.
