Product description

The Siemens 1FK7042-2AC71-1RB1 is a SIMOTICS S synchronous motor (1FK7-CT series) delivering 0.59 kW of power at 600V DC, with a continuous stall torque (M0) of 3 Nm at 100K and a nominal speed (NN) of 2000 rpm. This naturally cooled motor features IMB 5 mounting (IM V1, IM V3), a rotatable power connector, and an absolute encoder (AM20DQI) with DRIVE-CLiQ interface. It is configured with a feather key shaft, tolerance N, and includes an integrated holding brake, offering an enhanced IP65 degree of protection.

This motor is designed for demanding industrial automation applications where precise positioning, reliable holding, and robust environmental protection are necessary. Its IP65 rating makes it suitable for environments with high humidity, dust, or water exposure, while the holding brake ensures safety and position retention.
