Precision actuators to motorize linear stages
A
Newport Spectra-Physics product story
Edited by the Engineeringtalk editorial team
Jan 31, 2002
A new series of precision actuators offer backlash-free motion with high load capacity and up to 25mm travel range, using a preloaded belt drive system
Newport's VM series precision actuators offer backlash-free motion with high load capacity and up to 25 mm travel range.
They feature a M12 mounting interface and are the recommended choice to motorize our UMR8 and MVN80 linear stages, or SL and SK series optical mounts.
Precision motion is accomplished by a miniature DC servo or stepper motor with rotary encoder providing 50 nm position feedback.
A sophisticated, preloaded belt drive system converts the rotation of the motor shaft into linear travel while avoiding any backlash inside the system.
This allows very responsive motion ideal for alignment purposes.
An exceptional high load capacity of 120 N is achieved by a low friction design and precision guidance of the actuator's tip.
VM actuators are offered with three different travel ranges allowing exact match with the travel of your manual component.
To protect your investment, fixed limit switches are included, which are also used as reference home position.
Key features:- * Precision, backlash-free motion ideal for alignment purposes * Exceptional high load capacity of 120 N * Resolution: 0.05 um * Repeatability (uni-directional): 1.5 um * Vacuum-compatible versions up to 10uTorr * Precision, backlash-free motion ideal for alignment purposes * Exceptional high load capacity of 120 N * Low friction design enables high sensitivity with 0.3 um minimum incremental motion * Vacuum-compatible versions up to 10uTorr.
