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 ...

To fully appreciate the chief advantages of linear motors, it is helpful to compare them to ballscrews, another high-precision rotary-to-linear transmission system. Although typical ballscrews are ...

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 ...

In applications demanding precision and throughput, linear motor production systems usually need to be built from the ground up. Fractional microns accuracy requires feedback from an optical encoder, ...

Nippon Pulse linear shaft motors are available from Micromech in the UK. The underlying motor technology is a shaft of rare earth-iron-boron magnets inside a stainless steel tube, and a ‘forcer’ of ...

Once considered expensive and exotic, linear motors are at last becoming valuable workhorses in a variety of OEM applications. Besides delivering nanometer precision in the semiconductor and machine ...

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 ...
