SIEMENS 1FK2104-5AF10-0MA0 AC Servo Motor Brake

Buy online your SIEMENS AC Servo Motor with Brake reference 1FK2104-5AF10-0MA0 from our e-store Cnc-shopping, specialist in CNC machine-tools spare parts.

This SIEMENS SIMOTICS S-1FK2 AC synchronous servo motor, reference 1FK2104-5AF10-0MA0, is designed for precise axis motion in CNC machine tools and industrial automation systems. Featuring an integrated holding brake, it serves as a reliable replacement motor and industrial spare part for Siemens-based equipment requiring accurate closed-loop positioning and secure mechanical holding at standstill.

The 1FK2104 servo motor drives CNC feed and positioning axes, converting drive commands into controlled rotational motion. Its integrated holding brake helps secure the axis when power is removed, making it particularly suitable for vertical Z axes, milling and drilling machines, fixtures, and mechanisms that must remain in position during machine stops or maintenance operations.

Depending on the machine generation and drive configuration, this motor may be integrated into Siemens systems using SINAMICS or SIMODRIVE servo drives under SINUMERIK CNC control. Before installing it as a drop-in replacement, verify the complete part number, encoder configuration, brake specifications, connector orientation, feedback interface, and electrical ratings to ensure compatibility with the existing drive system.

Manufactured in Germany, this servo motor is suitable for demanding industrial environments, including machining centers, CNC lathes, milling and drilling equipment, automated handling systems, and CNC retrofit projects requiring consistent positioning accuracy and reliable axis holding performance.

The SIEMENS 1FK2104-5AF10-0MA0 is specified with a rated torque of 2.4 Nm. Its listed power ratings are 0.75 kW at 3,000 rpm with a 380–480 V supply and 0.375 kW at 1,500 rpm with a 200–240 V supply, depending on the applicable configuration. Additional specifications include an integrated holding brake, an IP64 protection rating, a 19 × 40 mm cylindrical shaft, a 22-bit absolute encoder with 12-bit multiturn capability (AM22DQC), an OCC interface, and an adjustable M17-size connector. Confirm these specifications against the motor nameplate and technical documentation for the exact configuration before ordering.

This motor is a practical CNC replacement component, spare part, or emergency replacement unit for restoring machine operation following encoder faults, brake wear, or motor failure. Keeping a compatible unit in industrial spare inventory can help reduce downtime and simplify maintenance on critical axes. Matching the complete part number is particularly important for planned retrofits and field replacements.

Each motor can undergo appropriate inspection and testing by qualified technicians to check encoder feedback, brake engagement, and electrical performance under controlled conditions. Units are securely packaged for industrial shipping. Commercial warranty terms are provided with the order, and fast dispatch is available depending on stock availability.

For older Siemens CNC installations, this motor may also serve as a replacement for a hard-to-find or obsolete part. Cnc-shopping supports sourcing difficult-to-find Siemens servo motors and may offer motor repair or exchange services, depending on the unit’s condition and availability. Worldwide shipping is available to support industrial maintenance and retrofit projects.

Frequently asked questions about 1FK2104-5AF10-0MA0:

Which Siemens drives are typically used with this motor?
It is commonly paired with SINAMICS or SIMODRIVE servo drives depending on the machine’s generation and control. Confirm the drive model and feedback option to ensure interface compatibility.

Is the integrated brake suitable for vertical axes?
Yes, it is a holding brake intended to keep a vertical or inclined axis from drifting at standstill. Verify the brake torque and voltage against the machine’s requirements to confirm suitability.

How do I confirm drop-in compatibility for a replacement?
Match the complete Siemens code including all suffixes, encoder type, shaft and flange style, connector orientation and brake voltage. Sharing the motor nameplate and drive model with our team helps confirm a correct fit.

Can this be supplied as a refurbished unit?
Depending on inventory, units may be available as refurbished, tested or surplus stock. Lead times and condition options can be provided at quote stage.

Do you offer repair or exchange if my motor is not recoverable?
A repair service or exchange service may be proposed after inspection. Turnaround and scope depend on the motor’s condition and parts availability.
