March 20, 2019 - H2W Technologies introduced a voice coil driven, XY positioning stage with a precision bearing system, which is designed to minimize the amount of pitch, yaw, and roll in the system. The voice coil stage (VCS06-010-BS-01-MXY) is a closed loop positioning system that can be used for positioning applications. 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 2.085 inches [53 mm].
Each axis has a 0.62" [15.8 mm] stroke; generate 0.75 lbs [3.3 N] of continuous force and 2.25 lbs [10 N] of peak force.
Each axis is guided by precision linear ball slide assemblies. It includes a one-micron resolution magnetic linear encoder on each axis. This design utilizes a moving coil, which has a lower moving mass. Voice coil positioning stages are ideal for applications that require quick, short moves with fast settling times.
