The Siemens 1FK7042-5AF71-1UG3-Z is engineered as a compact synchronous servo motor, offering significant performance in a small package. It is capable of generating a torque of 3 Nm while reaching speeds up to 3000 RPM. The motor is rated at 0.82 kW, making it suitable for various applications requiring precise control. Cooling is achieved through natural air circulation, which helps maintain efficiency during operation.

For installation, this motor features a basic IM B5 flange-mounting configuration, but it also supports vertical mounting positions via IM V1 and IM V3 options. This flexibility is beneficial in different setups and configurations where space may be a constraint. The motor is equipped with rotatable power and signal connectors that can turn up to 270°, simplifying cable management and reducing installation complications.

The motor's shaft is a plain type and adheres to a normal tolerance level (N). It is designed without a holding brake, thus simplifying its construction. Furthermore, a multi-pole resolver (P=4) is integrated into the design for enhanced positional accuracy. The protection class rated at IP64 allows this servo motor to operate reliably in environments where exposure to dust and moisture is a concern.
