The USMSG part 3 – Determine the accuracy

Once we know our motor’s torque specification we’re almost ready to start looking at catalogs. We just need to define the level of accuracy or resolution that our motor and gear train need to have. This all comes, obviously, from our initial high-level specification. Let’s make it specific now.

The USMSG part 4 – Evaluate the torque curves

We’re getting close to being able to finally select a stepper motor for our application. Armed with a high-level¬†set of specs for our mechanism, a complete torque specification¬†for the motor, and a clear idea of what resolution and accuracy we need, it’s time to start looking at vendor catalogs and their torque curves to evaluate…

The USMSG part 2 – Define your pull-out torque

The most important step in the process has been done, or at least started, which is: defining the high level specification of your mechanism. Great, now it’s time to get specific with the details. In this step, we’ll define the required torque specs that will allow you to actually start searching on the catalogs.

The USMSG part 1 – Define your requirements

So you want or need to add some motion to your system, and you think a stepper motor is the right solution for your application? Great! But how do you start? Well, let’s start from the beginning: define the needs of your mechanism, a.k.a. your spec.

The Ultimate Stepper Motor Selection Guide

Stepper motors are ubiquitous. From clocks, to 3D printers, to CNC mills. From split flap displays to spaceships. They are everywhere. The nature of their operation makes them the ideal option for many different systems that can’t (or don’t want to) afford complex electronics for closed-loop motion control but still need positional accuracy. They are…
