Motion control and piezo systems expert PI (Physik Instrumente) introduces a new robust OEM walking motor drive, the N-331, with its configuration rooted in existing patented piezo actuator technology and a patented piezo stepping motion principle design. Based on the application of historically successful technology, the new design it is ideal for use in high-end applications that require extreme precision and durability. Unlike traditional electromagnetic motors, piezo motors do not create magnetic fields, nor are they influenced by magnetic or electric fields – a characteristics that is advantageous in applications from e-beam lithography to MRI technology. When large optics, detectors or camera set-ups in industrial applications need to be positioned with nanometer precision, it can be beneficial to cut the actuator power once the fine positioning process is complete. If a motor or actuator is dependent on a continuous current draw to hold a position, heat dissipation, electromagnetic fields and thermal effects may have negative influences on the performance of the system. PICMAWalk motors are self-clamping, i.e. at rest or in steady state mode, they automatically hold the position without any need for power. PI’s PICMAWalk piezo linear motor uses 8 PICMA® piezo actuators arranged in a V-shape similar to a classical V8 engine to achieve high push/pull and holding forces along with nanometer precision. The space-tested PICMA® actuators are highly reliable, providing 60N (13lbs) power-off holding force and 50N (11 lbs) push/pull force. The maximum velocity is specified at 15mm/sec (0.6 inch/sec) and loads up to 5kg (11lbs) can be positioned with nanometer precision. Open and Closed-Loop Designs The units are available with 3 standard travel ranges from 25 to 100mm in both open and closed-loop configurations. The closed-loop models incorporate a high-precision incremental encoder with nanometer resolution. The calculated piezo-mechanical resolution is better than 1/10 nanometer. For maximum precision and reliability, the piezo actuators are integrated in a solid-state flexure guiding system, free of stiction and friction. Flexure elements combine high stiffness and load capacity. They do not require maintenance or lubricants, are 100% vacuum compatible, function in a wide temperature range, and are intrinsically wear-free. Standard and Custom In addition to the standard models, custom designs for OEMs are available, facilitated by the modular design.

Nanopositioning design and engineering global leader PI (Physik Instrumente) delivers a new ultra-compact XY scanner and positioner powered by small integrated direct-drive ultrasonic piezoceramic motors (a single axis version is also available). The patented drives provide smooth motion with high resolution and the self-locking motor principle is a significant advantage over magnetic drive technologies: once the motor reaches a target position, it acts like a ceramic brake and locks the platform into place, providing extreme long term stability at zero driving current and heat generation. Long Travel, Compact, Fast and Quiet, Wide Dynamic Range The U-723 joins PI’s existing portfolio of compact linear stages. It provides more than 0.8” travel per axis (22x22mm), with a footprint of only 42x42mm (1.6x1.6”). Its low profile of 21mm (~0.8”) and miniaturized design allows for easy integration into existing systems, especially when space is limited. In addition to high speed motion up to 200 mm/sec, the low inertia (direct drive, no rotating parts) allows for a very dynamic start-stop behavior with settling times in the millisecond range. Based on the ultrasonic principle with drive frequencies >100kHz - way beyond the human hearing range -, the motors are very quiet. Displacement is generated in continuous sub-nanometric increments, leading to extremely smooth motion with a wide dynamic range from 1µm/sec to 200mm/sec. 10nm Sensor Resolution, Closed-Loop Operation, 2 Axis Precision Motion Controller Incorporated optical linear encoders provide position feedback with 10 nanometers resolution. Higher resolution stages are also available from PI. Due to the low power requirement of the ultrasonic motor, the U-723 can be integrated into mobile measuring and medical devices. Vacuum compatible versions are also available. Watch the U-723 in Action – scanning an array of optical diodes! High-End Motion Controllers, Software Package To take advantage of the operating principle, providing superior dynamic performance with settling times in the millisecond range while maintaining high resolution and smooth operation, ultrasonic motors benefit from advanced control strategies, such as automatic switchover between several static and dynamic PID parameter sets and adaptive frequency tracking. PI offers a number of ultrasonic motion controllers (C-867 and C-877 product families) available in desktop, rack-mount, and OEM configurations. An ASIC chip containing the motion control algorithms is also available for OEM customers. A comprehensive software package is included: drivers and example programs for LabVIEW, dynamic libraries for Windows and Linux, MATLAB are available.

High atop the Cerro Armazones in the harsh but extremely dry environment of the Chilean Atacama Desert, more than 2000 custom hybrid actuators will adjust 798 quarter ton segments in the primary mirror of the Extremely Large Telescope (ELT). As a leader in precision motion control solutions, PI (Physik Instrumente) designed a new type of actuator that would meet the extreme requirements and win the European South Observatory (ESO) contract. Hybrid Actuator Concept Solves the Nanometer Precision - High Load - Low Heat Conundrum PI’s ultra-precision actuator was developed to meet requirements such as: tracing performance better than 2nm RMS, force variation 0N to 900N, 15mm travel, minimized heat dissipation. Several concepts were simulated and tested before a winner was picked. The best results were achieved with a hybrid design based on the combination of piezo actuator, brushless motor, linear encoder and a hybrid controller to drive both the brushless motor and piezo actuator simultaneously based on the position feedback of an optical position sensor providing sub-nanometer resolution. Three actuators are required per segment. Why is this Precision Required? In order to perform similar to one 39m mirror (it is not feasible to make a single mirror of that size), all segments have to be aligned to each other to within nanometers all the time. The exact position of the mirror segments is influenced by several factors such as wind load, distortions, and vibration from the telescope structure, temperature fluctuations and varying gravity effects during tracking motions of the telescope. Smallest alignment errors between the mirror segments will degrade the optical performance of the telescope. How Large is Extremely Large? Touted as the largest telescope in the world, the 39 meter diameter ELT individual hexagonal mirrors measure 1.4 meters across and weigh about 500lbs each. The large aperture directly determines the light-collecting area, which in turn defines the exposure time. More area means that for a given amount of exposure time, the telescope can detect more distant (fainter) stars and look deeper into the universe. With its total surface area of close to 1000 square meters, the ELT is supposed to collect around 100 million times more light than the human eye and boasts about 250 times the light gathering area of the Hubble Space Telescope. The ELT is scheduled to see its first light in 2024.
