Extremely small!

Q-Motion® positioning systems close a gap which has not been covered by present drive technologies: Miniaturized design, high resolution at unlimited travel ranges and versatile designs.

Q-Motion® positioning systems use a piezomotor inertia drive to provide motion.

Precise!

The drive principle is based on a piezoceramic actuator. This changes its shape when electrical voltage is applied, all without inner friction. It can therefore follow any voltage profile: Dynamically and with high position resolution!

The actuator is controlled cyclically - fast in one direction, slow in the other. The challenge for construction and development is to adjust the mechanical system and control so that the slow motion feeds the runner and not the fast motion. The drive remains in place, the runner moves.

Versatile!

The piezo ceramic actuator and its mounting are small. The same applies to the optional positioning sensor, and in conjunction with suitable mechanical components, the result is a positioning system with the smallest dimensions: Linear positioning stage with 21 mm width, rotating tables with a diameter of 14 mm.

Being small has advantages in microassembly, optical metrology or for applications in an ultrahigh vacuum.

The only thing that is really big is the product spectrum of Q-Motion® stages.

Technology
Piezo-based inertia drives make use of the stick-slip effect: a piezoelectric actuator expands slowly and moves a rod. Due to its inertia, the rod is unable follow the fast contraction of the actuator and therefore remains at its position.
