New Lower Cost Voice Coil Positioning Stage from H2W

Published on August 8, 2013 at 4:50 AM

The engineers at H2W have developed a new lower cost voice coil positioning stage that incorporates dual mounting options.  H2W reduced cost by using a lower resolution encoder and simplified design.  This system includes optional air cooling that would allow the stage to achieve higher continuous forces. 

The stage has standard mounting holes that allow it to be mounted either vertically or horizontally.  In the vertical orientation, the lighter weight coil assembly is the moving component.  When the stage is oriented horizontally the overall height of the stage is reduced and the magnet assembly becomes the moving component.

The voice coil positioning stage (VCS20-020-LB-12) is a closed loop system that can be used for high speed positioning applications.  The stage is driven by the NCC type actuator (NCC20-18-020-1X) and is guided by precision linear recirculating bearings.  The voice coil has a 2.0" [50 mm] stroke; generates 2 lbs [8.9 N] of continuous force and 6 lbs [26.7 N] of peak force.  It includes a lower cost 12 micron resolution linear encoder.  There are two mounting options: one of which allows it to be oriented vertically with the coil moving, or mounted horizontally with the magnet assembly moving.  Voice coil positioning stages are ideal for applications that require quick, short moves with fast settling times.

Features:

  • Lower Cost
  • Dual mounting options
  • High acceleration
  • Compact footprint
  • Optional air cooling
  • Custom strokes and force configurations available
