New! FHA-C Series low-profile, hollow shaft, brushless servo actuators are now available in 4 new models with 5 reduction ratios that achieve high-precision rotary positioning. The new FHA-C-PR models round out the already successful brushless actuator line.
We improved the one way and bi-directional positioning repeatability of the FHA-C series to offer an optimal solution for those applications that require increased accurate positioning.

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

Key Features:

  • High torque
  • Large center through hole
  • Compact cylindrical design
  • Availability of a series of multifunctional control units

Known for its expert engineering and manufacturing, Harmonic Drive LLC products are relied upon every day throughout the motion control industry.
