FHA-C Rotary Actuator

These rotary servo actuators utilize Harmonic Drive® precision gears combined with a performance matched brushless servo motor and incremental encoder. The FHA has a low profile form factor and features a hollow shaft through the center of the output. This hollow shaft feature may be used to pass cables, tubing or lasers through the axis of rotation.

The FHA series is designed to operate with a wide range of third-party drivers, as well as Harmonic Drive LLC’s DDP Series and RTL Series.

Key Features:

  • Zero backlash
  • New ratios added: 80:1 & 120:1
  • High torque
  • Large center through hole
  • Compact cylindrical design
  • Availability of a series of multifunctional control units
  • Driver Communication - DDP & RTL (CANopen®), REL (EtherCat®) & HA-800 (available for MechatroLink™ and CC-Link®)
  • Safety Standard: EN60034-1:2010
