SIEMENS 1FK7060-5AF71-1UA0 Motor 3000rpm Resolver

Buy online your SIEMENS 1FK7060-5AF71-1UA0 Motor from our US e-store Cnc-shopping USA, specialist in CNC machine-tools spare parts.

The SIEMENS 1FK7060-5AF71-1UA0 is a synchronous servo motor from the 1FK7 series, designed for precise axis positioning and feed applications in CNC machine tools and industrial automation systems. It is commonly used as a replacement motor or spare part for SINUMERIK-controlled machines equipped with SIMODRIVE or SINAMICS servo drives.

This compact AC servo motor converts CNC commands into accurate rotary motion while its integrated resolver feedback system continuously provides position and speed information to the drive. Resolver technology is particularly valued in industrial environments because it is robust, resistant to electrical noise, and capable of operating reliably under temperature variations and harsh shop-floor conditions.

The 1FK7060 motor is frequently paired with SIMODRIVE 611 and SINAMICS S120/S110 systems when used with the appropriate resolver interface. It is commonly installed on X, Y and Z feed axes, as well as on auxiliary applications such as tool changers, indexing tables, handling systems and gantry drives. Matching the complete order number ensures full compatibility with the original mechanical dimensions, winding characteristics and feedback configuration.

This SIMOTICS S 1FK7 Compact servo motor delivers a torque of 6.0 Nm, a rated speed of 3000 rpm, and a power output of 1.48 kW. It features natural cooling, mounting configuration IM B5 (IM V1, IM V3), and a power/signal connector rotatable by 270°. The motor is equipped with a multi-pole resolver (P=4) with DRIVE-CLiQ interface, a keyed shaft with tolerance N, and has no holding brake. The enclosure offers an IP64 protection rating, making it suitable for demanding industrial environments.

In maintenance operations, this model is often selected to replace motors affected by resolver faults, winding failures, excessive vibration or bearing wear. Keeping an identical spare motor in stock helps reduce machine downtime and simplifies maintenance on similar installations.

Each motor can be tested on dedicated CNC simulators to verify feedback communication and operational performance before shipment. Protective packaging with shaft and connector protection ensures safe transport. The SIEMENS 1FK7060-5AF71-1UA0 is a reliable solution for maintaining and extending the service life of CNC machines and industrial motion systems based on SIEMENS SIMOTICS and SINUMERIK technologies.

Frequently asked questions about 1FK7060-5AF71-1UA0:

Which SIEMENS drives can operate this resolver version?
It works with SIMODRIVE 611 and SINAMICS platforms when the drive or sensor module supports resolver feedback. Confirm the installed interface before ordering to ensure signal compatibility.

Can this motor replace an encoder-equipped version of a 1FK7?
Only if the drive and parameter set are adapted for resolver feedback and the mechanical and electrical codes match. For a true drop-in replacement, use the identical ordering code and feedback type.

What should I verify for mechanical fit?
Check the full code on the nameplate for flange size, shaft style, keyway, and any brake or connector options. Matching the complete code ensures a direct field replacement without rework.

Is this suitable for retrofit projects?
Yes, it is commonly used in retrofit and maintenance projects when the existing drive accepts resolver input. It is a practical CNC replacement component for maintaining machine uptime and standardizing spares.
