Rotating MagLev sample manipulator

In synchrotron beamlines, samples are analysed, while precisely positioned in the X-ray beam.

Current systems typically use a set of stacked stages based on piezo or stepper motors. To enable higher throughput and performance, MI-Partners has developed a magnetically levitated sample stage. The stage can be controlled in six degrees of freedom (6-DoF), with an infinite rotation around the vertical axis (z-axis) and a stroke of 3 mm along the x-, y- and z-axis. The stage is based on a novel electromagnetic actuator and positioning metrology system. This Mikroniek article presents its development and relisation. (Image courtesy of MI-Partners)

Order of frictions and stiffnesses…

For lumped systems consisting of different frictions and stiffnesses, there has been confusion in literature about hysteresis curves and virtual play for many decades.
