FHA-C Mini

FHA-C Mini is Harmonic Drive's compact hollow-shaft servo-actuator family for precision joints with limited installation space. Each unit combines a synchronous servo motor, backlash-free strain-wave gearing and an integrated output bearing. The bearing supports radial, axial and tilting loads, allowing a mechanism to attach directly to the actuator without a separate support bearing.

About FHA-C Mini

FHA-C Mini is Harmonic Drive's compact hollow-shaft servo-actuator family for precision joints with limited installation space. Each unit combines a synchronous servo motor, backlash-free strain-wave gearing and an integrated output bearing. The bearing supports radial, axial and tilting loads, allowing a mechanism to attach directly to the actuator without a separate support bearing.

The family covers 8C, 11C and 14C sizes with 30:1, 50:1 and 100:1 ratios. Maximum torque spans 1.8 to 28 newton-metres, maximum output speed ranges from 60 to 200 rpm, and hollow-shaft diameters run from 6.2 to 13.5 millimetres. Incremental RS-422 and multi-turn absolute EnDat feedback options support different motion-control architectures in compact robots and precision machinery.
