Product description

The Siemens 1FK7042-3BK71-1RA0 is a SIMOTICS S HI synchronous motor designed for high-performance industrial automation. It features a rated power of 0.94 kW, a DC link voltage of 600V, and a maximum speed of 6000 rpm. This naturally cooled motor conforms to IMB 5 (IM V1, IM V3) mounting standards and includes a Pt1000 temperature sensor, a rotatable power connector, and a high-resolution absolute encoder with a DRIVE-CLiQ interface.

This motor is ideally suited for applications requiring precise control and high dynamic response, such as in robotics, machine tools, and advanced material handling systems. The absolute encoder provides accurate position feedback without requiring homing, enhancing operational efficiency and reducing downtime.

Stanlo Automation, a veteran-owned distributor of surplus industrial automation parts, offers this Siemens 1FK7042-3BK71-1RA0 motor. We are committed to providing reliable components and excellent service. Trust Stanlo Automation for your Siemens automation needs.
