High Dynamic Linear Actuators - LHD series

INTENDED USE AND APPLICATIONS


The high dynamic actuators of the LHD (Linear High Dynamic) series are the best solutions to move masses and/or tools with high frequency and on short strokes, assuring an outstanding positioning precision and functioning to all intents and purposes as a high performance electronic cam.
The performances of the actuator can also be defined by controlling the force developed.

MAIN FEATURES
  • anodised aluminium structure
  • direct drive (ironcore linear motor)
  • positioning transduction using an optical linear encoder.
The versions with aerostatic support guides are longer lasting and more reliable since they are NOT subject to creep phenomenon (typical of rolling bearings systems), which, in case of high frequencies of motion inversion, is particularly serious.
