PICMAWalk walking drive

The PICMAWalk walking drive combines the high reliability of the PICMA® actuators with the innovative stepping principle of the already established NEXLINE® and NEXACT® drives. Eight actuators arranged in the shape of a V ensure reliable and the highest possible feed motion with a maximum of 60 N holding force, 50 N push/pull force, and a maximum of 15 mm/s velocity.

The excellent liftoff behavior of the actuators combined with the perfectly matched flexure guides ensure extremely high durability of the drive over a travel path of 30 km, even for high-demanding continuous load in industrial applications such as alignment of large optics, detectors, and camera set-ups.

The modular design of the drives offers the possibility of implementing individual, customized requirements quickly and inexpensively. The robust PICMAWalk walking drive is a reliable and durable drive solution for nanometer precision positioning of loads up to 5 kg.

PICMA® piezo actuators

PICMA® actuators have all–ceramic insulation and their performance and lifetime are therefore far superior to conventional actuators. The ceramic insulation layer protects the monolithic piezoceramic block against humidity or failure due to increased leakage current. In this way, an especially high reliability is achieved even under extreme ambient conditions. In contrast to motorized drives, there are no rotating parts or friction. The piezo actuators are therefore free of backlash, maintenance, and wear.

Flexure guides

A flexure guide is an element free of stiction and sliding friction, which is based on the elastic deformation (bending) of a solid (e.g., steel) and does not have any rolling or sliding parts. Flexure elements have a high stiffness and load capacity. They do not wear, require no maintenance, are 100 % vacuum compatible, function in a wide temperature range, and do not require any lubricants.
