Buy online your SIEMENS 1FK6060-6AF71-1EH0 Brushless Servo motor from our UK e-store Cnc-shopping UK, specialist in CNC machine-tools spare parts.

The 1FK6060-6AF71-1EH0 from Siemens is a brushless synchronous servo motor from the 1FK6 series, designed for precise CNC axis control and positioning applications. When paired with a compatible SIEMENS drive, it provides reliable closed-loop motion control for linear and rotary movements in machine tools and industrial automation systems.

Commonly used on feed axes, rotary tables, tool changers, gantry systems, and handling equipment, this motor delivers a rated torque of 6.0 Nm and a rated speed of 3000 rpm. Its brushless synchronous design ensures high reliability, reduced maintenance requirements, smooth low-speed operation, and fast dynamic response for demanding motion-control applications.

The motor is equipped with an EnDat 2048 S/R absolute encoder (A-2048), providing accurate position feedback and excellent repeatability. It also features an integrated holding brake, a smooth shaft with tolerance N, and a power/signal connector that can be rotated by 270°, allowing flexible installation in space-constrained environments.

Designed for IM B5 (V1, V3) mounting and natural cooling, the motor offers IP64 protection, making it suitable for industrial environments where dust, vibration, and machine-tool contaminants are present. Depending on the specific machine configuration, it is typically used with SINAMICS or legacy SIMODRIVE servo drive systems.

When replacing an existing unit, it is important to match the complete 1FK6060-6AF71-1EH0 ordering code to ensure full mechanical, electrical, and feedback compatibility. Its compact flange-mounted design makes it a popular choice for maintenance, retrofit, and repair projects where minimal installation changes and fast commissioning are required.

Manufactured in Germany, this servo motor is recognized for its durability, precision, and long service life. It is frequently used as a replacement solution for motors experiencing encoder faults, bearing wear, or drive-related alarms, helping maintenance teams reduce downtime and restore machine performance quickly and efficiently.

Frequently asked questions about 1FK6060-6AF71-1EH0:

Which SIEMENS drives are typically used with this motor?
It is commonly integrated with SINAMICS S120 or SIMODRIVE 611 depending on the exact feedback and options in the full ordering code. Always match the existing motor code and verify the drive interface and firmware before replacement.

What must be checked for a drop-in replacement?
Confirm the complete ordering code, mechanical mounting, shaft dimensions, keyway or coupling fit and the feedback type. Matching these items ensures correct parameterization and commissioning on the existing drive.

Can it be supplied as a refurbished unit or through exchange?
Depending on availability, we can provide a refurbished unit or arrange an exchange service. Units are functionally tested and can include a test report to support maintenance documentation.

Is this motor suitable for retrofit projects?
Yes, the 1FK6 footprint and flange design suit many retrofit scenarios where an older 1FK6 is installed. Verify mounting pattern, connector orientation and encoder compatibility to ensure a smooth installation.
