## Notes

Compact hollow-shaft AC servo actuator: pancake BLDC motor plus zero-backlash Harmonic Drive strain-wave gear. FHA-C Mini family sizes 8C/11C/14C with ratios 30/50/100:1. For FHA-14C at 100:1 the maximum (peak/momentary) torque is 28 N·m and continuous/rated torque is about 6.8 N·m; maximum output speed 60 rpm. 'Zero backlash' is the manufacturer strain-wave claim (recorded as 0). Positioning accuracy about 90 arc-sec (1.5 arcmin); repeatability not published in accessible sources, so left null. 24VDC integrated-drive version communicates via CANopen (4-wire) with an EtherCAT option. Weight about 1.65 kg per Radwell distributor listing for the exact FHA-14C-100-D200-M1-SP part. Quote-only pricing.
