New Low Profile XY-Theta Voice Coil Positioning Stage

H2W Technologies introduces a high acceleration, voice coil driven, XY-Theta positioning stage with a precision bearing system, which minimizes the amount of pitch, yaw, and roll in the system. 

Features

  • Low-profile
  • Three-axis motion control
  • High acceleration
  • Compact footprint
  • Custom strokes and force configurations available

VCS02-005-BS-01-MXYT

The voice coil stage (VCS02-005-BS-01-MXYTh) is a closed loop positioning system that can be used for positioning applications that require a limited rotation theta stage integrated. The stage utilizes a custom low-profile design that utilizes a unique electromagnetic circuit design. The motor has a two-axis planar coil assembly that interacts with a common magnetic circuit.  This circuit design allows for a minimal overall height of 2.93 inches [74.5 mm].

Each linear axis has a 0.23" [6.0 mm] stroke; generate 0.50 lbs [2.2 N] of continuous force and 1.50 lbs [6.6 N] of peak force.  The X and Y axes are guided by precision linear ball slide assemblies. It includes a one-micron resolution magnetic linear encoder on each linear axis.

The theta axis has a rotary displacement of 10 degrees, a continuous torque of 2.2 in-lbs [0.25 Nm], and a peak torque of 6.5 in-lbs [0.73 Nm].

There is also encoder feedback on the theta axis that has 239000 counts per revolution.

This design utilizes a moving coil in all three axes, which has a lower moving mass that enables the highest possible acceleration. Voice coil positioning stages are ideal for applications that require quick, short moves with fast settling times.
