This paper discusses the technology behind stepper motor linear actuators, what makes them different, and concludes with a detailed example illustrating how they should be sized to move a given load.

The combination of a high-torque step motor and precision spindle not only provides L2018 series linear actuators with a resolution of 5 µm, it also enables 40 N of thrust in compact form.

Stepper motors, gear trains and timing belts from old ScanJets can be found for pocket change any day of the week. For cheap and accurate linear motion, we couldn’t come up with a build that ...

We’ve seen plenty of motor projects, but [Jeremy]’s DIY Tubular Linear Motor is a really neat variety of stepper motor in a format we certainly don’t see every day. It started as a design ...

These are effective but limited systems. In contrast, integrated linear actuators convert rotation to translation inside the motor itself to eliminate components and boost output force and accuracy.
