Original Metabo armature (rotor) — part no. 310012030. Direct-fit replacement rotor for the 230 V motor used in Metabo random-orbit sanders, designed to restore smooth motor operation when the commutator or rotor windings are worn or damaged.

What it is: a 230 V armature assembly (rotor/commutator and shaft) manufactured to Metabo’s original specifications for the matching brush holders and field coil in these machines. It is the rotating core that sits inside the field coil and mates with the carbon brush set and bearings already listed for these models.

Fits these Metabo models (examples): SXE 3125 (type 00443000) and SXE 3150 (type 00444000) — the same part number 310012030 is shown in the official Metabo spare-parts breakdowns for both machines. The SXE 3125 is the 310 W class random-orbit sander that uses this 230 V armature.

Notes for repair: intended as a drop-in replacement for the original armature; when replacing it, it’s common practice to inspect/replace the carbon brushes and bearings (the parts list shows the matching brush set and field coil for these models) to ensure reliable operation after the swap.

Quality: this is the original Metabo-specified armature built for the listed SXE models, so you get the correct fit and electrical rating for the tool.
