CoograDrive®

HighLoad 8mm - Type 1

Technical Supply Specifications

Features

  • High torque capacity
  • Robust control without feedback system
  • Preloaded ball bearing
  • Extreme dynamic
  • High reliability

Description

The CoograDrive® HighLoad 8mm - type 1 micro positioning system combines extremely small outer dimensions with high torque capacity. The robust operating behaviour of this micro positioning system 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 low-backlash CoograDrive® gear with a reduction ratio of 80:1.
