KeevoDrive®

HighAcc 10mm - Type 2

Technical Supply Specifications

Features

  • Zero backlash at ultra high resolution
  • High repeatability
  • Robust control without feedback system
  • High load capacity of output bearing
  • High reliability

Description

The KeevoDrive® HighAcc 10mm - type 2 is a micro positioning system based on an eccentric with eccentricity of 2000 µm and travel range of up to 4000 µm. The micro positioning system can easily be operated in an open loop control, as it is driven by a stepper motor with 20 steps per rotation. At the heart of this high-reduction and reliable micro system is a zero-backlash MaalonDrive® gear with a reduction ratio of 1000:1.
