Quick response and high speed
The Piezo LEGS 20 N enclosed linear motor is intended
for use in a large range of applications; laser and optics
applications, moving mirror mounts, replacement for
micrometer screws etc. The very high speed dynamics and
nanometer resolution makes it ideal for numerous applications.
The LEGS technology is characterized by its outstanding
precision. Fast speed and quick response time, as well as
long service life are other benefits. In combination with the
nanometer resolution the technology is quite unique.
The motor is ideally suited for move and hold applications or
for automatic adjustments. 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. The LTC20 linear motor is available in two different
mounting versions.
Operating modes
The motor can move in full steps (wfm-steps), or partial steps
(microsteps) giving positioning resolution in the nanometer
range. Speed is adjustable from single microsteps per second
up to max specified.
Controlling the motor
PiezoMotor offers a range of drivers and controllers. The most
basic one is a handheld push button driver. Another option is
an analogue driver that regulates the motor speed by means
of an ±7 V analogue interface. One of the more advanced
alternatives is the PMD101 Microstep Driver/Controller.
This product enables the user to vary the waveform as well as
speed. The PMD101 is equipped with encoder signal inputs
for close loop control. The microstepping feature divides full
step cycle into maximum 2048 increments which results in
microsteps as small as two nanometers.

Design your own driver
Some customers prefer to design their own driver for ease
of integration or for even higher waveform resolution (subnanometer range). In this case PiezoMotor can provide
information to assist in the design.
