We’ve all heard linear motors, like those propelling Maglev trains, described as “unrolled” versions of regular electric motors. The analogy is apt and helps to understand how a linear motor works, ...

Low-friction, high-stiffness ball guides support on one rail (top) or two (bottom). The trade-offs for this performance are higher cost and more noise. The shortest path between two points is a ...

A slider-crank mechanism is a typical design which converts rotary motion into linear motion. It is achieved by connecting a slider and a crank with a rod. Figure A depicts a mechanism utilized as a ...

Novel bi-phase piezo motor enables accurate linear motion in an extremely compact package, new from PI. PI’s B-421 miniaturized piezo stages provide 10 nm positioning resolution in an extremely ...

This is a preview. Log in through your library . Abstract In this paper the optimal linear, positive schemes for constant-coefficient advection in two or three dimensions are presented. These are the ...

A lot of projects require linear motion, but not all of them require high-accuracy linear slides and expensive ball screws. When just a little shove for a door or the ability to pop something up out ...

PI (Physik Instrumente), a global leader in precision motion control, nanopositioning and piezo technology solutions, announces the release of the V-141 linear motor stage family, the most compact and ...
