System compatibility

MDD112C-N-030-N2L-130PB1 belongs to Rexroth Indramat MDD servo motor family,matched with DKC/DDS series Indramat servo drives.Widely applied in CNC machine tools,automation assembly lines,press-fit and material handling workstations.This is a discontinued legacy spare part for equipment maintenance replacement.

Function

MDD112C-N-030-N2L-130PB1 is Rexroth Indramat permanent magnet synchronous servo motor.It converts electrical energy into precise mechanical rotary motion for axis positioning.The built-in digital encoder feeds back real-time rotor position and speed to servo drive for closed-loop control.It is fitted with an electromagnetic holding brake to lock shaft when power cuts off,preventing axis sliding.The built-in temperature sensor monitors winding temperature to protect motor against overload shturl.cc adopts lifetime lubricated bearings for long-term stable operation.It acts as motion execution component for high-precision automation equipment.

Installation

Mount MDD112C-N-030-N2L-130PB1 onto machine flange and tighten mounting bolts.Align coupling and check concentricity.Connect power cable and encoder cable to servo drive according to wiring drawing.Check insulation resistance before power commissioning.

Interface

‑3-phase motor power connector

‑Encoder feedback connector

‑Brake power terminal

‑Motor temperature sensor terminal

Circuit feature

High-density permanent magnet rotor design,low torque ripple,shock and vibration resistant,stable performance for machine tool workshop environment.

Feature

MDD112C-N-030-N2L-130PB1 is obsolete Rexroth spare part.Typical faults:bearing noise,encoder failure,brake not release,winding insulation aging,shaft seal oil leakage.Inspect winding,encoder and brake before replacement.This motor must match corresponding Indramat servo drive model,direct substitution without inspection is not recommended.

Diagnostic

When encoder damage,winding overheat or brake malfunction occurs,the servo system will trigger alarm and stop axis movement.

Built‑in function:Precise rotary motion output,real-time position feedback,power-off shaft holding,winding temperature monitoring,used as Rexroth Indramat servo motion system spare replacement.
