Harmonic Drive RKF Servo Actuators

Harmonic Drive RKF combines a strain-wave gear with an AC servo motor and flange output. The manufacturer identifies it as an actuator without a hollow shaft, compatible with selected third-party drives and its REL/RTL drive families. Listed family peak torque is 56–330 Nm, with maximum output speeds of 45–90 rpm depending on the selection.

Engineering Assessment
A useful compact geared axis when an external compatible drive and flange-output arrangement suit the machine. Its integrated gearing and motor simplify component matching, but the peak family rating does not establish continuous operating torque.
Applications
Compact precision indexing and rotary positioning axes with an external compatible servo drive.
