Linear motors are becoming increasingly practical for general motion. Many are used for long strokes of a few feet or more. One new design, however, where the magnets move relative to a stationary ...

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 motors are synchronous motors: Current is applied to the coil to form an electromagnet. The coil then synchronizes itself to the magnetic field generated by the permanent magnets in the magnet ...

In the next few weeks, linear motors will face their ultimate litmus test. After years in the eye of a swirling technical storm, surrounded by doubters who say they're too expensive, supported by a ...

Linear induction motors (LIMs) convert electrical energy into linear thrust without intermediary mechanical transmission, rendering them ideal for applications ranging from urban rail transit and ...

A majority of automated systems using linearmotors today rely on a rotary servo motor coupled to a ball screw,belt-drive, rack-and-pinion, or even a cam-follower mechanism which convert therotary ...

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.
