• Direct drive - backlash free

• Microradian resolution

• Simple drive electronics

• No power draw in hold position

• Quick response and high speed

The Piezo LEGS Rotary 80mNm motor is intended for a large

range of applications. Very high speed dynamics and micro-

radian precision makes it ideal for numerous applications.

High torque output in a small package is also beneficial.

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 micro

radian 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 are needed to create motion. This means the

motor has no mechanical play or backlash. The Piezo LEGS

80mNm motor is available in a standard version, and a vacuum

version.

Operating modes

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

(microstepping) giving positioning resolution in the micro

radian range. Speed is adjustable from micro radians per

seccond 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 regulate the motor speed by means of

an ±7 V analouge 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 in to 2048

increments.

Design your own driver

Many customers prefer to design their own driver control for

ease of integration or for even higher waveform resolution

(sub-Lirad resolution). In this case PiezoMotor will provide all

relavant information for a successful design.
