SIEMENS 1FT6082-8AH71-4EH1 Servo motor 4500rpm

Buy online your SIEMENS 1FT6082-8AH71-4EH1 Servo motor from our e-store Cnc-shopping, specialist in CNC machine-tools spare parts.

The SIEMENS 1FT6082-8AH71-4EH1 is a 1FT6 series AC synchronous servo motor designed for high-precision motion control in CNC machine tools equipped with SINUMERIK control systems. It delivers accurate positioning, smooth speed regulation, and excellent dynamic response, making it an ideal replacement motor or spare part for maintenance, repair, and retrofit applications.

Designed to operate in closed-loop control with SIEMENS SIMODRIVE 611 servo drives, this motor provides a rated torque of 13 N·m and a rated speed of 4500 rpm, ensuring precise control of feed axes on machining centers, CNC lathes, grinding machines, and automated production equipment. It is equipped with an AM2048S/R encoder for accurate position feedback and a 24 V DC holding brake, making it particularly suitable for vertical axes and applications requiring secure load holding during power-off conditions.

Its compact flange-mounted design allows easy integration into a wide range of industrial machines while providing excellent resistance to vibration, temperature variations, and demanding production environments. The complete part number 1FT6082-8AH71-4EH1 defines the exact mechanical, electrical, and feedback configuration, ensuring direct compatibility with the original motor and minimizing commissioning time during replacement.

This servo motor is commonly selected to replace units affected by encoder failures, bearing wear, or winding damage. Installing a matching replacement helps restore machine performance quickly while minimizing production downtime. It is also widely used in preventive maintenance programs and retrofit projects involving legacy SIEMENS SINUMERIK motion systems.

Each motor can be supplied as a tested unit after functional verification by qualified engineers on dedicated CNC servo test benches. Testing includes encoder feedback verification, electrical performance checks, and smooth running throughout the operating range. Units are carefully packaged for industrial transport and are covered by the Cnc-shopping warranty. Repair, exchange, refurbished unit, and obsolete part sourcing services may also be available to help extend the operating life of SIEMENS CNC installations.

Frequently asked questions about 1FT6082-8AH71-4EH1:

What drive systems are typically used with this motor?
It is commonly paired with SIMODRIVE 611 drive modules controlled by SINUMERIK systems on CNC machine tools. This pairing provides closed-loop control for precise axis positioning.

Is it a drop-in replacement for an existing 1FT6082-8AH71-4EH1?
Yes, when the full code matches the original, the mechanical interface and feedback configuration are aligned for a straightforward swap. This limits adjustments and helps return the axis to service quickly.

Can it substitute other 1FT6 variants with a different code?
Use the exact code for guaranteed compatibility. Different suffixes can indicate changes in shaft, connectors or feedback device that may not match your current setup.

What is the rated speed?
This unit is specified at 4500 rpm. Actual operating speed is managed by the drive parameters within the CNC system.
