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 ...

Linear motors are very quick and precise for positioning, but are also capable of slow, constant-traverse speed for machine heads and slides, as well as tool and part-handling systems. A variety of ...

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 ...

Any electrical motor, from an idealized viewpoint, consists of two sets of magnets—one set stationary, one set free to move—placed in special geometric relation to one another. For most practical ...

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 ...

Dunkermotor, now part of AMETEK Precision Motion Control, has released its first ServoTube linear motors and actuators catalog with technical specifications and drawings that cover 1,346 standard ...
