MaalonDrive® HighAcc 6mm - Type 1

MaalonDrive®

HighAcc 6mm - Type 1

Technical Supply Specifications

Features

  • High repeatability
  • Compact build up
  • Zero backlash at high speed
  • Easy controllability
  • Preloaded ball bearing

Description

The MaalonDrive® HighAcc 6mm - type 1 micro servo actuator is driven by a brushless DC motor with rated voltage of 6V and integrated encoder with a resolution of 256 pulses per rotation. At the heart of this extremely miniaturised and yet absolutely reliable micro positioning system is a zero-backlash MaalonDrive® gear with a reduction ratio of 120:1. The application can be directly connected by means of the preloaded ball bearings on the output shaft.
