System compatibility

6KP1143003X1B1 belongs to Rexroth 6KP series servo motor family,matching Rexroth servo drive systems,widely used for CNC machine tools,automated assembly lines,handling equipment and robotics.This is a legacy spare part for industrial equipment maintenance replacement.

Function

6KP1143003X1B1 is a three-phase permanent magnet synchronous servo motor.It converts electrical energy into precise mechanical rotation output.It receives speed and position commands from servo drive,realizes high-precision positioning and speed regulation.The built-in holding brake locks the shaft when power is off to prevent load slipping.

Installation

Mount 6KP1143003X1B1 on mechanical base,tighten mounting bolts.Connect power cable,encoder cable and brake cable according to wiring diagram.Check coupling alignment before power-on commissioning,avoid excessive radial and axial load.

Interface

‑Motor power terminal

‑Encoder signal connector

‑Brake power terminal

‑Shield grounding terminal

Circuit feature

High density winding design,low torque ripple,fast dynamic response,overload resistant,strong anti-interference,suitable for harsh workshop industrial environment.

Feature

6KP1143003X1B1 is obsolete Rexroth spare part.Typical faults:encoder failure,winding insulation aging,brake wear,shaft bearing damage.Inspect winding resistance,encoder signal and brake function before replacement.This servo motor must match corresponding Rexroth servo drive,direct substitution without inspection is not recommended.

Diagnostic

When motor winding damaged,encoder fault or brake failure occurs,the drive will trigger overload or position feedback alarm,axis positioning deviation or shaft slipping.

Built‑in function:Precise rotary motion output,position and speed closed-loop control,power-off load holding,used as Rexroth automation servo system spare replacement.

Product Brief

6KP1143003X1B1 is Rexroth 6KP series synchronous servo motor with brake,used for high precision motion control.Verify drive model,encoder protocol and torque requirement before ordering.ESD protection required during handling and installation.
