Piezo LEGS® Linear Twin 20N

(Z* PiezoMolor

Direct drive - backlash free

Nanometer resolution

Simple drive electronics

No power draw in hold position

Quick response and high speed

The Piezo LEGS 20N linear motor is intended for a large

range of OEM applications. Design focus has been for ease

of integration. The very high speed dynamics and nanometer

precision makes it ideal for numerous applications.

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

backlash. The Piezo LEGS 20N linear motor is available in a

standard version and a vacuum version.

Mechanical and electrical connection

The motor is easily integrated in your application using the

drive rod mechnaical adapter. Drive rods are supplied in dif-

ferent lengths (30, 40, 50, 60, 70 and 101.8 mm).

The motor has two electrical connectors which are connected

in parallel to the driver.

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.
