PBA’s Circular Voice Coil Positioning Stage is a compact stage ideal for closed-loop short stroke positioning applications where precision, repeatability and low speed/force ripple are of utmost importance.
CVCA stages are built with precision cross roller guides that provide high rigidity to complement the high acceleration capability of the CVC module which has very low electrical/mechanical time constants and zero hysteresis. A perfect combination for majority voice coil applications requiring precise quick oscillation at high accelerations of light payloads.
– Cross roller bearing for excellent precision and rigidity
– Zero cogging, zero-backlash and zero hysteresis
– Low moving mass, fast response
– Integrated linear encoder
– Ease of use, plug and play
– Excellent reliability
– Sub-micron resolution possibilities
