Non-magnetic
Direct drive - backlash free
Microradian resolution
No power draw in hold position
Quick response
The Piezo LEGS Rotary 50mNm motor is non-magnetic. It
is intended for a large range of applications where there is
demand for non-magnetic material in motor. The 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
50 mNm non-magnetic motor is available in a standard
version, and in a vacuum version.
Operating modes
The motor can move in full steps (wfm-steps), or partial steps
(microsteps) giving positioning resolution in the microradian
range. Speed is adjustable from 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 ~0.5 microradians.
PMD101
Design your own driver
Some customers prefer to design their own driver control for
ease of integration or for even higher waveform resolution. In
this case PiezoMotor can provide information to assist in the
design.
