PI's own piezo ceramic production allowed them to develop proprietary piezo-motor drives; PILine® ultrasonic linear motors, NEXLINE® and NEXACT®-Piezowalk-drives have been implemented successfully in many OEM applications.
Compared to conventional drive concepts the integration effort is higher, so that we recommend a minimum annual quantity of >100units/year to start the evaluation of these motors. For smaller quantities we offer complete PILine stages including encoders, guiding and controllers.
NEXLINE® und NEXACT® Piezowalk-Drives
The patented NEXACT® and NEXLINE® PiezoWalk®-Drives unify large (principally unlimited) travel ranges with high mechanical stiffness. Holding forces up to 600N and resolution in the pm range are possible. They have been honored with the SEMI TIS award.
PILine® Ultrasonic drives
PILine® Ultrasonic motors are based on a patented piezoceramic drive concept. They are extremely light and flat and offer many advantages over conventional electromagnetic motors: faster response, max speed up to 800mm/s, self blocking at power off, non-magnetic, back-lash free.
