How to calculate angular velocity from hybrid stepping motor?

[Mongkol]

Dear All,
I am building plasma table by using hybrid stepping motor. I am little puzzled on calculation. Who know the formula to find angular velocity of hybrid stepping motor? I want to take it to find the force(kgs) which is possible of motor to drag load.

Here's my spec. of hybrid stepping motor.
1) 1.8 degree per step.
2) Rate current at 2.7 Amps.
3) Phase resistor at 2.9 Ohm.
4) Phase inductor at 17.5 mH.
5) Holding torque at 850 N.cm min.( about 1200 oz.in)
6) Detent torque at 24.5 N.cm max.
7) Rotor inertia at 2500 g.cm2
8) Lead wire at 8 wires.

Hope your help

Dear All,
I add some details. It can work at 80 -160 VDC.

Force (ounces) = ((2 x pi x torque)/ lead) x screw efficiency.

You'll need a torque chart for you motor to find it's torque at any given rpm.

Hello Gerry,
Thanks for your help. My system is T5 timing belt,not ball screw.Do you have other formula?
