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 ...

Abstract: In order to reduce the volume and improve the torque/thrust density of linear rotary motor (LRM), a novel structure LRM with moving coils is proposed, which has only one set of stator, rotor ...

Abstract: This paper proposes a variable gain fractional-order terminal sliding mode (VGFOTSM) control for position tracking of the permanent magnet linear synchronous motor. Specifically, practical ...
