Stepper Motor Torque Calculator

Calculate stepper motor torque needed for a given load.

Load Weight (kg)

Lead Screw Pitch (mm/rev)

Acceleration (mm/s2)

Friction Coefficient

Formula

Torque = Total Force x Pitch / (2 x PI x 1000)

What safety factor should I use?

Use a 2x safety factor to ensure the motor handles peak loads.

Does speed affect torque?

Yes. Stepper motors lose torque as speed increases.
