Piezo New Piezo LEGS® Caliper 20N

Piezo LEGS Caliper 20N

PiezoMotor is happy to present the new Piezo LEGS® Caliper 20N motor. The motor is intended for the stage market. It is made as a plug-in unit for ease of assembly in linear or goniometer stages. The aim is to miniaturize the total envelope and thereby set new standards. The product can replace any conventional motor solution because it is more precise (sub-nanometer resolution), has great speed dynamics, and will give a much more compact complete stage. Stall force is set to 20 N with a maximum stroke of 40 mm. 
When the motor is in hold position it does not consume any power. The drive technology is direct, meaning no gears or lead screws are needed to create linear motion. This means the motor has no mechanical play or backlash. In combination with the nanometer resolution the technology is quite unique.

LC20 is designed for build-in to linear or gonio stages. Its motor, both compact and strong, delivers predictable sub-micron, direct-drive motion without backlash. Resolution extends to single nanometer level or below. Gear-heads and linear screws are not needed, which reduces the overall size. Compared with traditional motors, LT20 often fits in tight locations where it delivers up to 20 N force. Its friction drive ensures full-force, power-off locking and its Piezo LEGS® technology helps any 'move-and hold' application benefit from high precision, instant response and low power consumption.
