Piezo Stepping Motor Basics
NEXLINE® High-Force Drives for Nanopositioning NEXLINE® systems are based on very rugged, high-efficiency shear and clamping actuators and incorporate a preloading mechanism to provide pushing and holding forces up to 600 N with high lifetime. The rigid design with resonant frequen- cies of hundreds of hertz allows the construction of very stiff structures and helps to sup- press vibration. The analog operating mode can be used for dithering and active vibra- tion cancellation. N-215 high-load NEXLINE® linear drive provides holding forces to 600 N and 20 mm travel
Compact NEXACT® Drives for Moderate Forces NEXACT® drives use bending actuators which combine the feed forward and the clamping cycles. They provide push/pull forces to 15 N with maximum velocities of more than 10 mm/s at low operating volt- ages of 40 V. The compact and cost-effective NEXACT® drives are available with various drive electronics, ranging from cost- effective OEM drives for open- loop operation in stepping mode to the sophisticated E-861 servo-controller for high- resolution, closed-loop linear NEXLINE® linear actuator principle translation stages.

Ultrasonic Piezo Motor Basics Features and Advantages of PILine® Ultrasonic Piezomotors Compact Size: the direct- drive principle allows the de- sign of ultra-compact trans- lation stages. The M-662, for example, provides 20 mm travel in a 28 x 28 x 8 mm package. Low inertia, high accelera- tion, speed and resolution: PILine® drives achieve veloci- ties to 500 mm/s and accele- rations to 10 g. They are also very stiff, a prerequisite for their fast step-and-settle times – on the order of a few milliseconds – and provide Principle .design of a PILine® ultrasonic piezomotor-driven translation stage. resolution to 0.05 µm.
