XYZ Voice Coil Positioning Stage

H2W Technologies designed the VCS20-20-03-MC-01-XYZ as a 3-axis positioning solution where compact size and cost were important. Using voice coil motors, instead of 3-phase brushless linear motors, significantly reduced 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. It 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″ [50.8 mm] stroke; 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″ [6.4 mm] stroke; 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.

Features:
• Compact, small footprint positioning stage
• Light moving mass
• Three axes of coordinated motion
• Custom strokes, forces, and feedback resolution configurations available
