Every time I say I’m going to a trade show I am questioned about it: “Ugh, such a hassle”, “But there’s lots of people!”, “The food is terrible!”, “Really? They’re pointless”, and my favorite: “Boring, they’re always the same”. So I thought I should do a quick post about my reasons for going to and…
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…

How to get an engineering job at a design firm
I am a Senior Design Engineer at Pensa and recently have added the role of Engineering Intern Coordinator. This new extended role puts me in charge of coordinating the tasks of our current interns and of giving them guidance and advice. But more importantly and better related to this post, it gives me the responsibility of interviewing and evaluating…
Old school music blasting on the ear drums. Eyes reading old school writings of colorful yesterdays. Re encountering myself with my old school thinking. Mind trying to make sense of all that nonsense. Now it’s time for old school blogging.
Work-life balance, Mark Watney style
Over the past months I got really excited about The Martian, both the movie and the book… But I mean, who hasn’t? It’s one of those super believable sci-fi stories with an awesome character in an incredible setup and lots of SCIENCE. What could be better than that? But ok, nerd side aside, what does…
