Piezo LEGS® Linear Twin-C 20N

Direct drive - backlash free

Nanometer resolution

Simple drive electronics

Optical mount interface

Quick response and high speed

The Piezo LEGS 20N 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 precision makes

it ideal for numerous applications. The motor is available with

different mounting options.

The LEGS technology is characterized by its outstanding

accuracy. 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 back-

lash. The Piezo LEGS linear motor is available in two different

mounting versions.

Operating modes

The motor can move in full steps, shorter steps or partial

steps (micro-stepping) giving positioning resolution in the

nanometer range. Speed is adjustable from nanometer 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. The more advanced alternatives

are the PMD90 Microstep Driver/Controller and the PMCM51

Multichannel Microstep Driver/Controller. These products

enable the user to vary the waveform as well as speed. They

are equipped with quadrature encoder signal inputs for

control. The microstepping feature divides full step cycle into

2048 increments which results in microsteps as small as two

nanometers.

Design your own driver

Many customers prefer to design their own driver control for

ease of integration or for even higher waveform resolution

(sub-nanometer range). In this case PiezoMotor will provide

all relevant information for a successful design.
