Selection of Stepper Motor

04/29/2011 6:03 AM

i have a load of 500 N,place on a shaft, max torque 1820 N-mm, it has to carry on lead screws and it should travel 6 meter in one minute.Only information of how much this load is travelled required.

I calculated, v(meter/min)=pi*Dia*N(rpm), N=75 rpm and Power=T*R / 63025=0.02 hp

please guide i should select a stepper motor of some other.

type of motor and specifications. please give some link. my calculations are correct

Your post is unclear, and does not give enough information.

500N is a force.

Do you actually have a mass which is to be moved? If so, what is the mass (in kg)? Is it to be moved horizontally? Is the only requirement to move the 6m in 60 seconds (i.e. is there a maximum acceleration rate which should not be exceeded, or maybe a region where the velocity should be constant)? Can you estimate a frictional component of load? What does this "max torque" figure apply to?

Your formula for velocity has little, if anything, to do with leadscrews.

If you want help, please explain more clearly, giving as much information as you can.
