Miniature Linear Alignment Systems Linear Motor Table

PBA MINIATURE LINEAR MOTOR AXES AND XYTeta DIRECT DRIVE SYSTEMS

The PAS series are direct drive compact miniature linear and rotary stages with a particularly low profile, which can be combined as an alignment system with up to 3 axes and can thus perform a complete XYθ movement.

 

The PAS series of miniature linear and rotary modules are ideal for short stroke / limited angle positioning applications where precision, repeatability and low speed/force ripple are paramount.

 

Each PAS module is driven by PBA linear and rotary direct drive motors and features built-in precision crossed roller guides that provide high rigidity and precision in both the mechanics and the high-resolution linear and rotary encoders; the high acceleration capability, very low electrical/mechanical time constants, zero backlash and virtually no hysteresis make PBA's PAS miniature positioning systems a highly accurate positioning system that is particularly suitable for alignment processes involving image processing, such as semiconductor and liquid crystal processing.

 

Further miniature linear stages for short linear strokes with high dynamics are available based on PBA's voice coil motors in classic pot design (CVCA) but also as flat voice coil motor axes (RVCA).

 

The advantages of a prefabricated system of direct drive axles are obvious:

  • direct drive technology
  • compact and low profile:
  • Linear module
    • 65x73x19mm,
    • stroke 10mm
    • 4.3N duration 30N peak;
  • Rotary module
    • 65x77,1x20,1mm
    • angle of rotation +/-25°
    • 90mNm continuous, 0.72Nm peak
  • cross roller bearing for outstanding precision and rigidity

PBA LINEAR MOTOR AXES TABLES AND DIRECT DRIVE MOTION SYSTEMS

Our partner PBA has been established as a linear motor and direct drive  manufacturer for almost 20 years, especially in the Asian market. Innovative strength, quality and technical support and service are the guiding principles of our partner. Our direct drive linear motors offer high force density, high rigidity and do not require any maintenance.

 

In addition to the linear motors as components, with our manufacturer PBA we also offer complete linear motor axes or linear motor tables with integrated guide and encoder. There are variants with both the ironless linear motors of the DX series and the iron-core linear motors of the PIXB series.

 

The integrated linear motors can be supplied as compact linear axis, as linear motor axis (also with several coil in a multihead configuration) and also as direct-drive gantry systems.

 

The advantages of a prefabricated system of direct drive axes are obvious:

  • no own design effort
  • professional assembly and testing of the performance at the supplier's premises
  • guaranteed accuracy
  • access to the complete range of direct drive linear motors from PBA: wide range of choices
  • fast set-up

 

Of course, the integration of PBA rotary direct drive torque motors is also possible, so that complete system solutions for your drive task can be developed with you and for you.
