Product description

The Siemens 1FK7042-2AF71-1UH0 is a SIMOTICS S-1FK7 synchronous motor offering a combination of features for demanding automation tasks. This motor provides 0.82 kW of power at 600 VDC, with a nominal torque of 3 Nm and a speed of 3000 RPM. It is naturally cooled and designed for IMB 5 mounting (IM V1, IM V3). It includes a rotatable power connector, a multi-pole resolver with the DRIVE-CLiQ interface for precise feedback, a smooth shaft (tolerance N), and a holding brake. The degree of protection is IP64.

This motor is well-suited for applications requiring precise position control, holding capability, and advanced digital communication. Its IP64 rating makes it suitable for general industrial environments. Applications include robotics, servo-driven systems, and automated manufacturing equipment where a brake is necessary for load holding.
