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 ...

Linear actuator uses a lead screw driven by a permanent magnet dc motor to create linear motion from a dc voltage. When power is removed linear actuator will hold its position. However, if a force ...

[Will Finucane] of Revolt Labs/Mad Science Blog was looking for a way to keep his cats happily fed while away on a short vacation, so he put together a cheap and easy automatic feeder to ensure that ...

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 ...
