The VCS12-1000-LB-C voice coil positioning stage uses H2W voice coil motor NCC12-60-1000-2X to generate a continuous/peak force of 100 lbs [454 N]/300 lbs [1362 N] with a total stroke length of 1.2 in [30.5 mm]. It comes supplied with a linear bushing which allows for smooth motion. The motor coil is the moving part of the assembly in order to reduce the moving mass of the system. The voice coil motors have been mounted centered and parallel with the bearing assembly in order to reduce the overall height and length of the system. Springs are supplied so that it will work ideally in oscillatory systems, so that the actuator can move as a balanced spring mass system.
