Siemens 1FK7063-2AF71-1QB0 SIMOTICS S 1FK7-CT Synchronous Servo Motor 11Nm 3000rpm

The Siemens 1FK7063-2AF71-1QB0 is a SIMOTICS S 1FK7-CT synchronous servo motor rated 11 Nm continuous torque (M0 at 100K) at 3,000 rpm, with 5.6 A rated current and a shaft height of 63 mm. It uses natural cooling, carries IP64 protection, and includes a Drive-CLiQ single-turn absolute encoder (20-bit), with a holding brake.

Technical Specifications

Selection Notes

At 1.37 Nm/A this winding trades torque-per-amp for a higher 3,000 rpm optimum speed than the 2,000 rpm winding built on the same shaft-height-63 frame, drawing 5.6 A to hold the same 11 Nm continuous torque. The integrated holding brake retains axis position once drive power is removed, which matters for vertical or overhauling loads running at this higher base speed.

Applications

Matches synchronous servo axes needing 11 Nm at a 3,000 rpm base speed in packaging and handling equipment, where the holding brake secures the axis when the drive is de-energized. The Drive-CLiQ encoder interface connects directly to Drive-CLiQ-enabled Siemens drive systems without separate encoder cabling.
