Siemens 1FK7044-4CF71-1RH0 servo motor

The exact listing identifies 1FK7044-4CF71-1RH0 as a Siemens SIMOTICS S-1FK7 high-dynamic synchronous servo motor. The exact technical listing reports 1.2 kW, 3000 RPM, 4.5 Nm static torque, 3.45 A rated current, natural cooling, IM B5 mounting, an absolute 20-bit plus 12-bit multi-turn DRIVE-CLiQ encoder, a plain shaft, a holding brake, and IP64 protection.

System role

Rebuilt from individual evidence

Evidence and limits

The exact listing identifies 1FK7044-4CF71-1RH0 as a Siemens SIMOTICS S-1FK7 high-dynamic synchronous servo motor.

This motor converts controlled drive output into rotary motion for the connected machine axis.

Unknown: the installed 1FK7044-4CF71-1RH0 configuration, compatibility, and current commercial status require separate verification.

System role

This section explains what the product does and where it acts in the surrounding system.

Function
Produces controlled rotary motion as the documented servo motor in a motion-control axis.
System position
Sits between a compatible drive and the machine mechanical load.
Upstream / inputs
A compatible drive provides controlled electrical output to the motor.
Downstream / outputs
The motor shaft drives the connected machine axis.
Limitations
Unknown: the installed 1FK7044-4CF71-1RH0 configuration, compatibility, operating condition, current commercial status, and local service coverage.

Evidence ledger

Facts, inferences, and unknowns are kept separate.

Facts

  • The exact listing identifies 1FK7044-4CF71-1RH0 as a Siemens SIMOTICS S-1FK7 high-dynamic synchronous servo motor.

    Confidence: medium

  • The exact technical listing reports 1.2 kW, 3000 RPM, 4.5 Nm static torque, 3.45 A rated current, natural cooling, IM B5 mounting, an absolute 20-bit plus 12-bit multi-turn DRIVE-CLiQ encoder, a plain shaft, a holding brake, and IP64 protection.

    Confidence: medium

Inferences

  • The documented arrangement places this servo motor between a compatible drive and the machine mechanical load.

    Confidence: medium

    Rationale: The exact-reference identity and technical description identify the component type and the interfaces or mechanical characteristics needed to place it in the documented system path.

Unknowns

  • Unknown: the installed 1FK7044-4CF71-1RH0 configuration, firmware, wiring, drive pairing, load, and operating condition.

    Confidence: low

    Missing evidence: No installation record, firmware, wiring, drive pairing, load, or controller parameter export was captured in the individual research.

  • Unknown: current stock, price, lead time, repair condition, warranty, and local service coverage for 1FK7044-4CF71-1RH0.

    Confidence: low

    Missing evidence: Current stock, price, lead time, repair condition, warranty, and local service coverage were not established as product facts.
