The two degrees of freedom in movement can be actuated independently or concurrently. The actuators can be run using a two-axis stepper-motor driver and chopper and/or microstepping drives. The Size 14 delivers up to 50-lb thrust and 18 oz-in. of torque. The rotary part is a 1.8° step angle and capable of being microstepped for finer resolutions. The linear portion is constructed of high-performance thermoplastic nut material. The actuators are available in resolutions ranging from 0.00012 to 0.00192 in./step. The S14 targets applications requiring precise two degrees of freedom, controllable motion, pick-and-place equipment, robotics, and a wide array of instrumentation.
