The LR17 is a high precision motor in the second
generation of Piezo LEGS Rotary. It is intended for a
large range of applications where high speed dynamics
and positioning with precision is crucial. High torque
output in a small package is also beneficial.

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 ±10 V analog interface.
More advanced alternatives are microstep drivers/
controllers in the 100- and 200-series. These products
allow for closed loop control and precise positioning.
The microstepping feature divides the wfm-step
into thousands of small increments which results in
microsteps in the microradian range. The PMD units are
straight forward to use, supports quadrature and serial
sensors, and have multiple I/O ports.

The Piezo 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 in hold position it
does not consume any power. The drive technology is
direct, meaning no gears are needed to create motion.
The motor has no mechanical play or backlash.
The motor comes with an integrated high resolution
magnetic encoder. Feedback from the encoder gives
resolution of 0.2 mrad (0.01º) in closed loop operation.
The open loop resolution of the motor is 0.1 µrad
(0.000006º).

Operating modes

The motor can move in full steps (waveform-steps), or
partial steps (microsteps) giving positioning resolution
in the microradian range. Speed is adjustable from
microsteps per second up to max specified. The motor
can be operated with feedback from the integrated
magnetic encoder to form a closed loop system.

Design your own driver

Some customers prefer to design their own driver for
ease of integration. PiezoMotor provides information to
assist in the design.
