high precision rotary table free sample

PI’s direct-drive rotary tables with frictionless, brushless, closed-loop torque motors provide the best combination of high accuracy, high velocity, and maximum service life. PI provides closed-loop direct drive rotary tables with both mechanical bearings and air bearings. Stage models with large apertures and low profile are available. The stage design is optimized for high speed, stiffness, and high load capacity. If completely friction-free and maintenance free motion with virtually unlimited lifetime is required, air bearing rotation tables are recommended. These ultra-precision, high-speed rotary tables provide vibration-free motion with extremely high accuracy and negligible runout, wobble and eccentricity errors. The lack of lubricants makes these also clean room compatible and ideal for any high-performance metrology application in optics, photonics, and semiconductor manufacturing, test and metrology related projects.

In contrast to worm gear driven rotary stages or belt-drive rotation stages, torque-motor direct drive stages eliminate play in gears, couplings or flex in drive belts, providing motion with zero backlash and excellent constancy of velocity, while achieving higher speed than worm-gear drives.

PI’s precision direct-drive, positioning tables can be used in high performance factory automation, research, semiconductor, and laser processing applications. Due to the use of brushless high-torque, motors with direct metrology position feedback, backlash is completely eliminated, and reliability is greatly improved.

With modern direct-metrology rotary encoders, sensor resolution down to 1/100th of a microrad is available on select models with large rotary table platforms, using the high interpolation factors

Based on the high encoder resolution and powerful servo controllers, the direct-drive rotary tables also provide excellent velocity control, which is required in automation applications including high-speed laser processing, indexing, and semiconductor wafer inspection.

Most Direct Drive Rotation stages can be mounted horizontally and vertically, and with combinations all 3 rotary degrees of freedom (3DOF, pitch, yaw, and roll) can be addressed.

M-035 series high precision rotary tables rotation stages feature high resolution, excellent repeatability and minimum wobble. These high performance rotational positioning stages are equipped with double ball bearings for minimum backlash and high load capacity. Both the rotation stage platform and the scale ring (graduated in 2-degree increments) can be independently coarse positioned over 360 degrees and then be locked by screws.

The basic rotary table version, M-035.D0, is equipped with a DC servo motor drive providing a positioning range of ± 6.3 degrees. A set of limit switches eliminates the possibility of overtravel. For the highest precision and highest performance, high speed air bearing rotary tables are recommended.

This compact closed-loop direct drive rotary table uses a 3-phase motor for maintenance free, frictionless power transmission. It comes in two variations, standard and with holding brake.

The self-locking design requires no holding current and provides excellent long-term stability. Three different diameters are available: 14 mm, 22 mm and 32 mm.

PI"s air-bearing rotation stages provide the highest accuracy and smoothest motion of any commercially available rotation stage. With standard and custom designs these stages are designed for reference class applications.

The PI miCos line of goniometers and rotation stages is specialized on miniature stages with different motor drives (belt-drives, worm-gear drives) and also on ultra-high precision stages with torque motors, direct metrology and air bearings.

P-5x8 series, Z/tip/tilt nanopositioners are open-frame, high-resolution, piezo-driven stages providing Z motion to 240 �m and rotation around X and Y to 2.4 mrad with resolutions of up to 0.5 nm and 50 nrad. The 66 x 66 mm clear aperture is ideal for transmitted-light applications.

Goniometric cradles are used to rotate samples and objects to a precise angular position. The units here are equipped with precision servo and stepper motors and high-resolution encoders for angular position feedback.

This piezo platform can rotate a mirror or optic up to 2 mrad (4 mrad optical deflection) around two orthogonal axes. The parallel-kinematic, solid-state piezo drive system guarantees exceptional precision and very fast response in the low millisecond range and below.

Our direct drive rotary tables provide high torque and are easy to integrate. They contain high-energy magnets in a simplified mechanical design and drive loads directly without the need for a transmission mechanism or gearbox. It allows customers to build them right into a drive system for flexible placement and integration with cooling pipes and cables, for example.

We supply a wide range of frameless motors, and our adjustable motors include an optical encoder, scale, bearing and housing. Given our selection, it can be challenging to choose the best direct drive motor for your project. Our engineers prefer to help you find the right rotary table for your requirements.

In vertical movements, the engine must overcome gravity and additionally provide a force for vertical upward movement (F = mg + ma). In this case, the maximum load is determined by the maximum force divided by 9.81 m/s ². If the vertical force needs to be continuously maintained, the maximum load is the continuous power of the engine. For example, the maximum vertical load of the AUM2-S2 engine is 2.2 kg, since the continuous force of this engine is 22 N. If the load is borne by a counterweight (such as a spring), the AUM2-S2 engine can move a higher load in a vertical position.

There is no theoretical limit to the speed of a linear engine because there is no contact. However, speed is typically limited by the mechanical bearings. For example, the maximum speed for linear control systems with rails and guide cars is usually limited to 5m/s. Therefore, the speed for linear motors in most applications is limited to 5m/s. The use of ceramic ball bearings allows speeds of up to 10m/s. By using air bearings, higher speeds can also be possible.

Linear Motors can be used in cleanroom environments. In fact, many front-end semiconductor applications have linear motors in use. In wafer manufacturing plants, high-precision lithography machines, for example, use linear motors in XY positioning tables with very high accuracy (nanometer resolution) and submicron accuracy in cleanroom classes according to ISO 2.

The DGII Series is a line of of products that combine a high rigidity hollow rotary table with an AlphaStep closed loop stepper motor and driver package. It retains the ease of use of a stepper motor, while also allowing for highly accurate positioning of large inertia loads.

The gear-reduction mechanism employs precision gears along with a proprietary adjustment mechanism that eliminates backlash. The repetitive positioning accuracy from a single direction is ±15 sec., while lost motion in a positioning operation from two directions is 2 arc minutes. These characteristics make the DGII series the ideal choice for applications in which accurate positioning is a must.

By utilizing the high responsiveness of the stepper motor, moving a short distance for a short time is possible. The motors can execute commands without lag.
