Siemens 1FK7063-2AC71-1QA0 SIMOTICS S 1FK7-CT Synchronous Servo Motor 11Nm 2000rpm

The Siemens 1FK7063-2AC71-1QA0 is a SIMOTICS S 1FK7-CT synchronous servo motor rated 11 Nm continuous torque (M0 at 100K) at 2,000 rpm, with 4.4 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), no holding brake.

Technical Specifications

Selection Notes

The 2.08 Nm/A torque constant and 136.5 V/1000min-1 voltage constant put this winding at the low-speed, high-torque-per-amp end of the shaft-height-63 1FK7-CT range: it produces 11 Nm from only 4.4 A rated current, at the cost of a lower 2,000 rpm optimum speed than the faster windings built on the same frame. No holding brake is fitted, so a vertical or overhauling axis needs an external brake or a self-locking mechanical stage to hold position once drive power is removed.

Applications

Fits synchronous servo axes in machine tools, packaging, and material handling that need 11 Nm at a moderate 2,000 rpm base speed and where an external or gearbox-integrated brake already holds the load. The Drive-CLiQ encoder interface connects directly to Drive-CLiQ-enabled Siemens drive systems without separate encoder cabling.
