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 ...

The ABCs of PID control. Considerations for interfacing elements in the electrical circuit to accomplish those parts of the PID function for position control. Firmware code implementation.

An electric bicycle—it's a regular bicycle, but with a motor on it! There are enough moving pieces on these personal mobility vehicles to make buying one confusing. Even if you're pretty sure you know ...

Linear-motor driven plunger pumps are most efficient at transforming mechanical energy to hydraulic work in low-producing and highly deviated wells. Linear-motor driven plunger pumps (LMDPP) are most ...

Launching things with electromagnetism is pretty fun, with linear induction motors being a popular design that finds use from everywhere in hobby designs like [Tom Stanton]’s to the electromagnetic ...
