Siemens 1FK7063-2AH71-1QB0 SIMOTICS S 1FK7-CT Synchronous Servo Motor 11Nm 3300rpm

The Siemens 1FK7063-2AH71-1QB0 is a SIMOTICS S 1FK7-CT synchronous servo motor rated 11 Nm continuous torque (M0 at 100K) at 3,300 rpm, with 3.8 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

Same 0.92 Nm/A high-speed winding as the brake-less version of this frame, holding 11 Nm at 3,300 rpm optimum speed from 3.8 A, but with an integrated holding brake for vertical or overhauling loads. The brake lowers shaft torsional stiffness to 25,000 Nm/rad against the brake-less version's 34,000 Nm/rad, so use it only where power-off holding is actually needed.

Applications

Suited to vertical-axis or gravity-loaded synchronous servo applications needing 11 Nm at 3,300 rpm, where the holding brake removes the need for a separate mechanical lock. The Drive-CLiQ encoder interface connects directly to Drive-CLiQ-enabled Siemens drive systems without separate encoder cabling.
