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.
