Siemens 1FK7032-2AK71-1QB0 SIMOTICS S 1FK7-CT 1.15 Nm 6000 rpm Servo Motor

Siemens 1FK7032-2AK71-1QB0 SIMOTICS S 1FK7-CT servo motor delivers 1.15 Nm standstill torque and 0.5 kW rated power at 6000 rpm on a 600 V DC link. It is a 6-pole design with 1.3 A rated current, IP64 protection, a 20-bit single-turn absolute encoder (AS20DQI) with a DRIVE-CLiQ interface, and an integrated holding brake.

Technical Specifications

Selection Notes

This is the holding-brake version of the 600 V, 6000 rpm 1FK7032-CT variant: the brake raises rotor inertia to 0.750 kgcm² and lowers shaft torsional stiffness to 4,100 Nm/rad compared with the non-brake motor in the same frame. Choose it for vertical or gravity-loaded high-speed axes that must hold position when the drive is de-energized; for horizontal axes the non-brake version responds faster due to its lower inertia. Against the 300 V / 3000 rpm siblings in this frame, the 600 V DC link doubles rated speed to 6000 rpm at a lower 1.3 A rated current.

Applications

1.15 Nm at 6000 rpm with a holding brake suits vertical pick-and-place axes, Z-axis drives, and high-speed indexing stations where the load must not drop when the servo drive loses power.
