Harmonic Drive FHA-C H Hollow-Shaft Actuator

Harmonic Drive FHA-C H combines a hollow-shaft strain-wave reducer, brushless servomotor and selected motor feedback for an external high-voltage servo drive. Four frame families and three ratios provide distinct continuous and maximum operating limits. The full code also selects brake, encoder, cable exit and protection; the H winding alone does not make every unit IP65.

Applications and Industries
Consider FHA-C H for machine-tool, packaging, robot or other OEM rotary axes needing a compact hollow-shaft motor/reducer assembly and a matched external high-voltage servo system. The chosen protection and brake options must fit the actual installation.

Review Summary
Consider FHA-C H for a compact rotary axis that needs a central passage and an externally matched high-voltage servo system. Its value is the motor/reducer integration and defined feedback choices. Specify the complete ordering code and loaded duty, especially the P protection option and the separate continuous torque and speed limits.
