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 experiment ...

Stepper motor linear actuators provide thrust along a linear axis but cannot tolerate side loading. Supplemental guidance is needed to protect against external forces impacting the linear motion of ...

What an actuator is, and what the difference is between linear and rotary The three main energy types—electric, pneumatic and hydraulic—plus thermal, magnetic and piezoelectric What to keep in mind ...
