Small linear slide provides speed boost
Measuring only 8mm in length, the P-653 stage offers a travel range of 2mm and sub-micron resolution, combined with a holding force of 0.15N.
PI's P-653 piezo motor linear slide is significantly smaller than other miniature linear stages and provides significantly higher velocities and resolution This true linear motor system consists of only four parts and can replace classical drive elements like miniaturised motor/lead screw systems or other linear motors

The moving slider and the piezo motor are delivered assembled as a unit and already mounted on a PCB driver board, requiring only 5V DC supply voltage.
P-653-series PILine piezoelectric ultrasonic motor drives are ideal for OEM applications where quantities are high and space is at a premium.
The systems were optimised for moving small objects such as optical fibres, micro-optics, or micro-electro-mechanical elements fast and precisely.
These nonmagnetic ceramic motors can also be used in medical applications.
Motion is controlled by TTL voltage pulses applied to the driver electronics.
The self-adjusting driver creates the high-frequency, nanometre-level oscillations that make the ultrasonic ceramic motor move.
PILine linear piezomotors are based on an ultrasonic drive.
At the heart of the system is a rectangular monolithic piezoceramic plate (the stator), segmented on one side by two electrodes.
Depending on the desired direction of motion, the left or right electrode of the piezoceramic plate is excited to produce high-frequency eigenmode oscillations. Request a free brochure from PI (Physik Instrumente) ...
