Hi actually i looking for a stepper motor and a driver for my project. I have most of the specs i want but i still left with an important factor which is torque.
I have to use a stepper motor turn a aluminum rod which is 320mm for length and 28mm for diameter in one direction. I do not know the formulae to calculate the torque with only the dimension.
Please kindly advice the formulae to calculate the torque for it . Thanks
