RSF

The RSF series servo actuator combines a high performance brushless servomotor with a high accuracy Harmonic Drive® gearhead. When combined with a performance matched servo drive, the RSF actuator delivers precise, reliable motion control for machines requiring both high torque and long life. The RSF Series is designed to operate with a wide range of third party drivers as well as Harmonic Drive LLC’s RTL Series, and REL Series.

Key Features:

  • Zero backlash
  • Compact and lightweight
  • High Torque
  • Accuracy <1 arc-min
