The VCS20-20-03-MC-01-XYZ 3-axis positioning stage from H2W Technologies uses voice coil motors, instead of 3-phase brushless linear motors, to significantly reduce the overall size, weight, and cost of the system.
The VCS20-20-03-MC-01-XYZ is a closed-loop voice coil driven XYZ positioning stage and is ideal for three-axis positioning applications. It uses H2W voice coil motors NCC20-18-020-1A (XY Horizontal Axis) and NCC03-15-050-2X (Vertical Z-Axis). The XY Horizontal Axis motors have a 2.00-in. (50.8 mm) stroke and generate 2.0 lbs (8.9 N) of continuous force and 6.0 lbs (26.7 N) of peak force. The Vertical Z-Axis motor has a 0.25-in. (6.4 mm) stroke and generates 5.0 lbs (22.3 N) of continuous force and 15.0 lbs (66.8 N) of peak force. The 1.0-micron resolution encoders allow for precise positioning. It comes supplied with precise linear bearings that allow for smooth and rigid motion. The motor coil is the moving part of the assembly in order to reduce the moving mass of the system. Power is supplied to the motor via a high flex, high reliability flat ribbon cable.
Custom strokes, forces, and feedback resolution configurations are also available.
