[Raul] built a cheap linear actuator out of a drawer slide and a surplus flatbed scanner. A few builds we’ve seen, like the PCB drill press or the horribly inefficient thermostat, used linear ...

Linear motion is central to many moving machines, and the direct-drive nature of linear motors can simplify overall machine design in these applications. Other benefits include improved stiffness, ...

The first linear motor was conceived by Wheatstone more than 100 years ago. But large air gaps and low efficiencies prevented linear motors from being widely used. Though they still have relatively ...

For rotary or linear motors, motion is produced in the same way and the same basic physics and electromagnetic forces apply. The theory that produces "torque" in a rotary motor produces "force" in a ...

Precision screw jacks for accurate linear motion and reliable actuator performance. CALIFORNIA , CA, UNITED STATES, ...

Depending on the exact technology, typical linear motors can deliver unlimited strokes and (with feedback) accuracies to ±1 μm/100 mm. Speeds range from inches to 1,000s of inches per second.

We admit that this project doesn’t have very many details available, but it was just too neat for us to pass up. It’s a small linear motor which [ligonapProduktion] built after seeing a very brief ...

Up until now, linear motors have been designed primarily as flat stage motors complete with cradle and guide – a format that is not necessarily suitable for every application. But a new rotationally ...

To run a stepper motor smoothly, it's necessary to apply linear acceleration. However, conventional algorithms to generate linear acceleration require complicated mathematics, which makes it difficult ...

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 ...

With its Hunstable Electric Turbine, Linear Labs promises three times the torque, twice the power and a 10% increase in range in an electric vehicle over a typical permanent magnet motor. One problem ...
