Piezo motor
Piezoelectric motor with 20 N standstill force
The LT20 piezoelectric motor from PiezoMotor enables microstepping in the sub-nanomillimeter range.
The LEGS Linear Twin LT20 linear motor with direct drive from PiezoMotor has a standstill force of 20 N and does not require ball bearings thanks to the twin concept. The motor has a full-force switch-off interlock as a safety function and is available in a non-magnetic and a non-magnetic vacuum version in addition to a standard version in stainless steel for normal environments.
Piezoelectric motors are suitable for all applications where maximum precision and maximum miniaturization are required. In the motors from PiezoMotor, small ceramic legs arranged in pairs, so-called piezo LEGS, are extended or bent sideways by applying a voltage according to the inverse piezoelectric principle. In this way, the robust and high-precision linear motors perform backlash-free stroke movements in the nanometer or sub-nanometer range. The stroke of the LT20 is between 0 and 74.5 mm, depending on the length of its drive rod. Five lifting rods with lengths of 30, 40, 50, 60 and 100.8 mm are available.
