September 5, 2019 - H2W Technologies introduced a voice coil driven, positioning stage with a sliding contact bearing system. The voice coil stage (VMS06-008-LB-01) is a closed loop positioning system that can be used for positioning applications. The stage utilizes a custom design that utilizes a unique electromagnetic circuit design.
This design allows for a minimal cross section of 1.20 inches [30.5 mm] by 1.00 inches [25.4 mm].
The stage has a 0.60" [15.2 mm] stroke; generates 1.12 lbs [5.0 N] of continuous force and 3.36 lbs [15 N] of peak force.
Each axis is guided by sliding contact bushing assemblies. It includes a one-micron resolution magnetic linear encoder. This design utilizes a moving magnet, which has no moving wires, and has anti-rotation elements built-in to prevent shafts from slipping. Voice coil positioning stages are suitable for applications that require quick, short moves with fast settling times.
