The VCS08-700/08-350-AB-01-MC-XY is a high force, high acceleration, voice coil driven, closed loop XY positioning stage with air bearings. It is ideal for high force low velocity ripple positioning applications. It uses H2W voice coil motor NCC08-34-350-2X. Each voice coil has a 0.80" [20.3 mm] stroke; generate 35 lbs [159 N] of continuous force and 105 lbs [477 N] of peak force, or a combined 70 lbs [318 N] continuous force and 210 lbs [953 N] of peak force on the bottom axis. The bottom axis utilizes dual motors in order to double the force capability without having to integrate a single larger size motor. This helps reduce the overall size of the system. The 1.0-micron resolution encoder allows for precise positioning. It comes supplied with a non-contact air bearing (air bushing) which minimizes the amount of friction as well as the pitch, yaw, and roll in the system. 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. The voice coil motors have been mounted in-line with the bearing assembly in order to reduce the overall height and width of the system.
