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 … ...

It also helps to know how motor construction—not all motors are alike—affects performance and application. Otherwise you may end up with a design that works on paper, but bombs in the field.

Linear actuators are devices that convert any rotary or spinning motion into a linear (straight) motion. In simple words, they help machins move forward and backward. The most basic type of linear ...

Define the problem To begin a linear design, determine the mass of what moves and how fast it goes from A to B. We work in SI units, as they eliminate multiple conversion constants and can always ...
