Siemens 1FK7063-2AH71-1QA0 SIMOTICS S 1FK7-CT Synchronous Servo Motor 11Nm 3300rpm

The Siemens 1FK7063-2AH71-1QA0 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), no holding brake.

Technical Specifications

Selection Notes

At 0.92 Nm/A this is the lowest torque constant among the shaft-height-63 1FK7-CT windings covered here, which is what lets it reach the highest 3,300 rpm optimum speed in the set while still holding 11 Nm continuous. No holding brake is fitted, so a vertical or overhauling axis needs an external brake or self-locking stage to hold position with drive power removed.

Applications

Fits synchronous servo axes that need 11 Nm at a higher 3,300 rpm base speed, such as faster-cycling packaging or handling stations, 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.
