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.

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…

How many times we’ve heard about an online company’s sketchy privacy policy? Each passing day we are all more concerned about how much of our personal information is available on the web and permanently hosted and shared by questionable companies with questionable privacy policies and security systems. We then receive countless advice on keeping personal…

They are light and very strong structures that can handle loads in many orientations or directions. They are “easy” to build when made in large scale, there are many equations and tables to help with…
