Siemens 1FK7042-2AK71-1CB0 SIMOTICS S Motor

The Siemens 1FK7042-2AK71-1CB0 is a SIMOTICS S synchronous motor built for high-speed and precise automation applications. It delivers a rated power of 0.94 kW, operates with a DC link voltage of 600 V, offers a standstill torque (M0) of 3 Nm at 100K, and reaches a high nominal speed (NN) of 6000 rpm. This naturally cooled motor adheres to the IMB 5 (IM V1, IM V3) flange standard (Flange 1). It features a rotatable power connector and an integrated absolute encoder (24-bit + 12-bit multi-turn) with a Drive-CLiQ interface (AM24DQI) for superior position feedback. The shaft is designed with a feather key, tolerance N, and crucially, it includes a holding brake. The motor's enclosure provides IP64 protection.

This motor is ideal for demanding applications such as robotics, automated machinery, and high-precision manufacturing where both high speed, absolute positioning, and reliable holding are required. The multi-turn capability of the encoder allows for tracking position over multiple revolutions, while the holding brake ensures safety when power is removed.
