Hi guys,

I want a linear stepping motor to be able to apply an equivalent force 10 newton to push a syringe.
How do I read the data sheet here : http://www.haydonkerk.com/LinearActu...5/Default.aspx

To know if the motor is capable of applying such force?

Thanks,

Hi,
There's more work to do before selecting the motor. You want linear force, but motors rotate, so you need to design a machine to do the conversion. You need to know the length of the linear motion and its speed, then design a mechanism and probably a gearbox.

Hi, if you take a look at the page the motor has a threaded rod going through it so its already a linear motion.

It will depend on the speed at which you extend the actuator. Its power output is given by its linear velocity times the force it's developing, so you have a constraint there (since its power output is limited).

There's a graph of this relationship at the bottom of the page you linked.
