Air Bearing XY Voice Coil Positioning Stage generates high force.

Press Release Summary:

Air Bearing XY Voice Coil Positioning Stage generates high force.

Jun 04, 2014 - Offering 2-axis motion control, custom VCS08-700-08/350-AB-01-MC-XY is guided by precision, non-contact air bearings to minimize friction and reduce system pitch, yaw, and roll. Stage operates under closed loop position control, is driven by 3 NCC series moving coil type linear actuators guided by parallel air bearing shafts, and includes 1 micron resolution linear encoder on each axis. Each voice coil has 0.80 in. stroke and generates 35 lb continuous force (105 lb peak).

High Force Air Bearing XY Voice Coil Positioning Stage

Press release date: May 31, 2014

H2W introduces its latest custom XY voice coil positioning stage (VCS08-700-08/350-AB-01-MC-XY) which is guided by precision air bearings.  This minimizes the amount of friction and reduces the pitch, yaw, and roll in the system.  The stage is driven by three NCC series moving coil type linear actuators which are guided by parallel air bearing shafts.  It is operated under closed loop position control.  This system was designed specifically for an accelerometer testing application.

It includes a 1 micron resolution linear encoder on each axis and is ideal for high force low velocity ripple positioning applications.  Each voice coil has a 0.80 in [20.3 mm stroke; generate 35 lbs [159 N of continuous force and 105 lbs [477 N of peak force, or a combined 70 lbs [318 N continuous force and 210 lbs [953 N of peak force on the bottom axis.  Voice coil positioning stages are ideal for applications that require quick, short moves with fast settling times.

Bottom Axis - Dual NCC08-34-350-2X Motors
Top Axis - Single NCC08-34-350-2X Motor

- Non-contact air bearing (air bushing)
- Frictionless motion
- No wearing parts
- Low velocity ripple
- High force
- High acceleration
- 2 axis motion control
- Custom strokes, forces, and feedback resolution configurations available
