For linear motor-driven axes, resolutions can be well below 0.1 μm, and even into the nanometer range. The quality of the current loops determines whether the linear motor can hold a position ...

After evaluating several solutions, engineers chose a linear step motor, mounting the tray on the motor. It smoothly moves the tray in small increments, 12,500 steps/in., meeting the application ...

In addition to generating both the lift and the lateral motion required in pick-and-place machines with only a single linear track and a single forcer (consisting of three coils), the technology ...

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 … ...

Technically, the patented HET motor (described in some detail in the above video from Linear Labs), as described by Brad Hunstable, is a “3D Circumferential Flux Motor” with four rotors.
