Product description

The Siemens 1FK7034-5AK71-1LB5 is a SIMOTICS S synchronous servo motor from the 1FK7 Compact series, designed for precise and reliable motion control. It delivers 0.63 kW nominal power (PN) and 1.6 Nm continuous torque (M0) at 100K, with a nominal speed (NN) of 6000 rpm. This naturally cooled motor features a rotatable power/signal connector (270°). It is equipped with an AM20DQ absolute encoder (20-bit + 12-bit multi-turn) with a DRIVE-CLiQ interface, which causes a 10% performance derating. The motor has a shaft with a feather key and tolerance N, includes a holding brake, and offers IP65 protection for the main body and IP67 for the DE flange. It is finished in RAL7016 paint.

This motor is suitable for demanding applications in automation, robotics, and machine tools where accurate positioning, holding torque, and enhanced environmental protection are required. The RAL7016 finish is ideal for installations with specific color-matching needs.

Stanlo Automation, a veteran-owned distributor of surplus industrial automation parts, stocks the Siemens 1FK7034-5AK71-1LB5. We provide a reliable source for essential components, ensuring minimal operational disruption and efficient MRO procurement.
