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.
