Siemens 1FK7042-2AC71-1RB0 SIMOTICS S Motor w/ Brake
Siemens SIMOTICS S synchronous motor 1FK7-CT, 0.59 kW, 2000 rpm, with brake.
The Siemens 1FK7042-2AC71-1RB0 is a SIMOTICS S synchronous motor (1FK7-CT series) featuring 0.59 kW of power, a 600V DC bus voltage, and a continuous stall torque (M0) of 3 Nm at 100K, with a nominal speed (NN) of 2000 rpm. This naturally cooled motor is designed with IMB 5 mounting (IM V1, IM V3), a rotatable power connector, and an absolute encoder (AM20DQI) with DRIVE-CLiQ interface. It includes a shaft with a feather key, tolerance N, and importantly, an integrated holding brake. The degree of protection is IP64.
This motor is suitable for applications requiring precise motion control combined with reliable holding capabilities, such as vertical axes in robotics, automated storage systems, and machine tools where maintaining position under load is critical. The IP64 rating provides good protection against dust and water spray.
