1FT6105-8AF71-3EA1 industrial motor

1FT6105-8AF71-3EA1 is documented as an exact industrial component with a concrete system role; installation-specific limits remain explicit.

System function

Rebuilt from individual evidence

Evidence-backed specifications

Siemens identifies 1FT6105-8AF71-3EA1 as a SIMOTICS S synchronous servomotor.

The Siemens data sheet specifies 50 Nm, 3000 rpm, natural cooling, IM B5, absolute EnDat 2048 S/R, axial non-drive-end connector outlet, feather-key shaft, no holding brake, and IP65 sealing.

This system placement is an inference from the captured exact-reference evidence.

System role

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

Function: Converts controlled servo-drive electrical output into rotary torque for a machine axis.
System position: Sits between a compatible servo drive and the driven machine axis.
Upstream / inputs: Receives controlled three-phase electrical power and absolute encoder wiring from the servo drive.
Downstream / outputs: Transmits rotary torque to the machine mechanism under drive control.
Limitations: Unknown: installed drive compatibility, machine load, wiring, commissioning state, and current commercial availability.
