SIEMENS 1FT5044-0AF71-1-Z Servo Motor

Buy online your SIEMENS 1FT5044-0AF71-1-Z Servo Motor from our US e-store Cnc-shopping USA, specialist in CNC machine-tools spare parts.

This SIEMENS 1FT5 series synchronous servo motor is designed for CNC feed axes and precision positioning applications. Widely used on lathes, machining centers, grinders and automated equipment, it provides accurate closed-loop speed and torque control when paired with compatible SIEMENS drive systems.

The 1FT5044-0AF71-1-Z delivers 2.0 Nm torque at 3000 rpm and operates from a 600 V DC link. Featuring natural cooling, IP64 protection, tachogenerator and resolver feedback (TG and RLG), and power and signal connectors, it offers reliable performance for demanding industrial environments. The motor is supplied without a holding brake and is suitable for mounting configurations IM B5, IM V1 and IM V3.

Designed for use with SIEMENS motion platforms and SINUMERIK-controlled machines, this motor is commonly installed on X, Y and Z feed axes where smooth interpolation, rapid acceleration and precise positioning are required. Its compact design and robust construction make it well suited for both original equipment and retrofit projects.

For replacement applications, matching the complete reference number ensures compatibility with the original flange, shaft, connector arrangement and feedback system. Using the same motor specification helps minimize commissioning time and avoids unnecessary mechanical or electrical modifications.

Maintenance teams frequently select this model as a direct replacement for motors affected by bearing wear, feedback faults or winding failures. Keeping a compatible spare motor in stock helps reduce machine downtime and supports preventive maintenance programs on legacy SIEMENS installations.

Each unit can be supplied as a tested, refurbished or replacement motor, depending on availability. Motors are inspected by qualified engineers and can be verified on dedicated CNC test benches and servo motor simulators. Protective packaging, warranty coverage and worldwide shipping are available. Cnc-shopping also offers repair services, exchange programs and obsolete part sourcing to help maintain older SIEMENS motion systems and extend machine service life.
