How to Use

Using the Stepper Motor Sizing Calculator is straightforward. Enter the required parameters into the designated input fields, click the “Calculate” button, and the result will be displayed. This calculator aims to streamline the often complex process of determining the appropriate stepper motor size for a given application.


The formula for stepper motor sizing involves several factors, including torque, speed, and inertia. The most accurate formula for stepper motor sizing is:



Suppose we have an application with an inertia of 0.005 kg·m², a desired speed of 2000 RPM, and an acceleration of 1000 RPM/s². Plugging these values into the formula:


Q: How can I determine the inertia of my system?

A: The inertia can be calculated by summing the products of each component’s mass and the square of its distance from the axis of rotation.

Q: Why is torque required for stepper motor sizing?

A: Torque is essential as it represents the force required to move and accelerate the load.

Q: Can this calculator be used for other motor types?

A: No, this calculator is specifically designed for sizing stepper motors.
