Product Overview
The Siemens 1FK7060-2AF71-1UA0 SIMOTICS S Synchronous Motor is a permanent-magnet synchronous servo motor from the SIMOTICS S-1FK7 Compact family. It has a rated torque of 4.7 Nm at a 100 K temperature rise, a rated speed of 3,000 rpm and an optimum operating power of 1.5 kW. Its naturally cooled construction and IM B5 mounting arrangement suit servo-driven machinery requiring controlled rotary motion and repeatable positioning.
This motor variant uses a resolver R15DQ feedback system and a shaft with a feather key. The resolver supplies rotor-position information to a compatible drive, which uses the feedback to regulate motor speed and torque. The keyed shaft provides a mechanical connection for a compatible coupling or transmission component, making shaft-interface verification an important part of replacement selection.
The 1FK7060-2AF71-1UA0 has no integrated holding brake. Applications involving vertical axes, suspended loads or mechanisms that must remain stationary when power is removed require a separate assessment of the load-holding arrangement. Its IP64 protection rating and naturally cooled construction should also be considered when evaluating the installation environment.
For machine builders and maintenance engineers, the key selection points are the resolver interface, shaft configuration, motor-drive compatibility and required torque over the machine’s operating cycle. A motor from the same 1FK7 family is not automatically interchangeable if its feedback system, shaft or brake configuration differs.

Working Principle
The 1FK7060-2AF71-1UA0 converts electrical energy into mechanical rotation through the interaction between the stator’s rotating magnetic field and the rotor’s permanent magnets. A compatible servo drive regulates the motor current according to the commanded torque, speed or position.
The R15DQ resolver supplies rotor-position feedback. The drive interprets the resolver signals to determine rotor movement and electrical position, then adjusts motor current to maintain the requested motion. This feedback arrangement supports controlled acceleration, speed regulation and positioning when the motor is correctly matched to the drive and machine mechanics.
In a machine axis, the motor may accelerate a mechanism, maintain a commanded speed during production or position a component at a defined point. The actual response depends on the load inertia, transmission ratio, drive configuration and motion profile. The motor’s maximum torque and speed ratings should not be treated as continuous operating values; the complete operating cycle must remain within the applicable motor and drive limits.
The feather-key shaft transfers torque through a compatible mechanical connection. Correct coupling fit and alignment help prevent excessive vibration and mechanical loading. Because this version has no integrated holding brake, the machine must provide a suitable external holding solution wherever the load could move after the motor stops producing torque.
Role in a SIMOTICS S Servo Control Architecture
The 1FK7060-2AF71-1UA0 acts as the rotary actuator in a closed-loop motion-control system. The controller issues motion commands, the servo drive supplies regulated power, and the resolver returns feedback for motor regulation.

Technical FAQs
What is the difference between the 1FK7060-2AF71-1UA0 and an encoder-equipped 1FK7 motor?
The 1FK7060-2AF71-1UA0 uses an R15DQ resolver for rotor-position feedback. Other 1FK7 variants may use incremental or absolute encoders, so the feedback interface and drive compatibility must be checked before selecting a replacement.
Can this motor be used for a vertical axis?
It may be suitable if its torque, speed and thermal characteristics meet the application’s requirements. Because this version has no integrated holding brake, the machine must provide an appropriate load-holding arrangement where required to prevent unwanted movement when the motor is de-energized.
What does the feather-key shaft mean for mechanical installation?
The shaft uses a key and matching keyway to transmit torque through a compatible coupling or transmission component. The key, shaft interface and coupling must match the mechanical design, and alignment should be checked during installation.
What should be checked if the drive reports a resolver fault?
Inspect the resolver cable, connectors, feedback wiring and drive configuration. Confirm that the selected drive supports the R15DQ resolver and that the correct motor data have been entered before replacing the motor or feedback components.
