Request InfoPiezoMotor ABPiezoMotor AB has released LR17, a 17-mm-diameter piezo LEGS rotary motor with an integrated absolute encoder for compact motion applications. The device features 30-mNm stall torque from the motor and a self-locking friction drive to hold the motor in position without consuming power. The integrated 15-bit magnetic absolute encoder provides closed-loop resolution of 0.2 mrad. The Piezo LEGS technology enables submicroradian resolution in open loop. The LR17 model is the first motor in a series of four different sizes, the company said.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 10/19/2022Optical 3D Measuring MachineThe ScanBox Series 5 from ZEISS Industrial Quality Solutions is an optical 3D measuring machine that captures the entire surface geometry, as well as hole patterns and other characteristics of the...Photonics.com 3/20/2024Zoom 3D ScannerThe SmartScan VR800 from Hexagon AB is an optical 3D scanner with a motorized zoom lens that enables users to adjust data resolution and measurement volume entirely through software settings.
