Siemens 1FK7034-2AK71-1QA0 SIMOTICS S 1FK7-CT 1.6 Nm 6000 rpm Servo Motor

Siemens 1FK7034-2AK71-1QA0 SIMOTICS S 1FK7-CT servo motor delivers 1.6 Nm standstill torque and 0.63 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 no holding brake.

Technical Specifications

Selection Notes

This is the non-brake version of the 600 V, 6000 rpm 1FK7034-CT variant: without the brake, rotor inertia is 0.900 kgcm² and shaft torsional stiffness is 5,300 Nm/rad, both better than the holding-brake version in the same frame. Against the 300 V / 3000 rpm siblings in this frame, the 600 V DC link doubles rated speed to 6000 rpm and raises rated power to 0.63 kW at a lower 1.3 A rated current. Use it for high-speed horizontal axes where an external holding mechanism already exists.

Applications

1.6 Nm at 6000 rpm without a brake suits high-speed horizontal indexing, pick-and-place heads, and feed axes in packaging and assembly machinery where fast settling time outweighs the need for standstill holding torque.
