Product description

The Siemens SIMOTICS S synchronous servo motor 1FK7043-7AH71-1AH0 is a High Dynamic (HD) motor designed for precise motion control. It offers a torque of 3.1Nm at 100K, operates at 4500rpm, and has a nominal power of 1.23kW. This naturally cooled motor, built in IM B5 configuration, features a rotatable power connector and an incremental encoder (SIN/COS 1 VPP 2048 P/REV) for feedback. It includes a holding brake and has a degree of protection of IP64.

This motor is ideal for applications requiring high dynamic performance and accurate speed/position control where incremental feedback is sufficient, such as in robotics, machine tools, and material handling systems. Its robust design ensures reliability in industrial settings.

Technical note

Expert tip

The 2048 P/REV incremental encoder provides high-resolution position feedback, but requires the drive system to track position after power cycles, unlike absolute encoders.
