Product Name: PILine® Micro Piezomotor Linear Drive P-652

Product Description

P-652-series PILine® piezomotor drives are ideal for OEM applications where space is limited and masses are small. The P-652 may replace classical drive elements like rotary motor/leadscrew assemblies or other linear motors in a micro-system. The basic advantages PILine® piezo linear motors offer compared to classical drives are

• High velocity
• Compact size
• Self-locking at rest without heat dissipation

The integration of P-652 is simple because the moving sliders and the piezoceramic motor are already delivered as a unit. Mechanical and electrical integration must be assured by the system the P-652 operates in. 
The drive design was optimized for moving small objects such as fibers, optomechanical components, micromechanics or MEMS fast and precisely. 

Working Principle
P-652 drives employ a new, patented, ultrasonic piezomotor developed by PI. The highly compact, integrated piezomotor can provide accelerations of up to 2.5 g and velocities of up to 80 mm/s, together with high position resolution and—compared to its small size—high holding force. Because the ceramic stator is pressed against the sliders of the drive, piezomotor-drives resist motion with an intrinsic holding force when the unit is at rest. The result is very high position stability without the heat dissipation common with conventional linear motors. Furthermore, there are no gears, leadscrews or other mechanical components to contribute play or backlash. 

Operation with conventional controllers
P-652 drives are based on PILine® ultrasonic piezo linear motors. The high-frequency oscillations for the motors are created by a driver electronics, which can be operated by short 3-V-pulses. The excitation frequency of the driver electronics is self-adjusting to the resonant frequency of the ceramic motor, so individual tuning is not necessary.
