MaalonDrive®

HighAcc 8mm - Type 2

Technical Supply Specifications

Features

  • High repeatability
  • Zero backlash with optimised fit between speed and resolution
  • Robust control without feedback system
  • Preloaded ball bearing
  • Lifetime lubrication

Description

The MaalonDrive® HighAcc 8mm - type 2 micro positioning system combines high angular resolution, a simple stepper motor controller and small outer dimensions in one system. The robust operating behaviour is achieved by the stepper motor with 20 steps per rotation, thereby allowing the unit to easily be operated in an open loop control. At the heart of this micro positioning system is a high-reduction, zero-backlash MaalonDrive® with a reduction ratio of 160:1.
