The Wacker Neuson Motor Armature Complete is a genuine OEM component designed for the EH 50 series electric hammers, including the EH 50/230 hex 25x108, EH 50/230 27x80, EH 50/230 hex 28x152, EH 50/230 hex 28x160, and EH 50/230 hex 28x160 BR models. As a direct Wacker Neuson OEM part, the is wound and balanced to the original specification, ensuring consistent electrical output and proper motor performance. Sourcing a genuine replacement protects the integrity of the hammer's drive system and keeps the tool operating at the power level it was engineered to deliver. Confirm your model number against the fitment list before ordering to ensure a correct match.
Key Features
- OEM-Wound to Correct Output Specification — Armature windings meet the original resistance and output ratings for the EH 50 series motor, maintaining full striking power and consistent RPM under load.
- Direct Drop-In Replacement — Machined to match the original shaft diameter, commutator dimensions, and mounting configuration, so installation aligns with the existing motor housing and brush assembly without rework.
- Broad EH 50 Series Coverage — Fits multiple EH 50/230 variants including hex 25x108, 27x80, hex 28x152, hex 28x160, and hex 28x160 BR electric hammers.
- Restored Impact Performance — A worn or shorted armature causes reduced striking force, overheating, and erratic tool behavior; replacing it with this genuine part restores full rated performance.
- Electrical Safety Assurance — Genuine OEM construction ensures correct insulation ratings and winding integrity, reducing the risk of electrical faults in a 230V tool environment.
The motor armature is the rotating core of an electric motor — it carries the current that generates the magnetic field responsible for converting electrical energy into mechanical rotation. In an electric demolition hammer like the EH 50, that rotational force drives the hammering mechanism, so the condition of the armature directly determines striking power and consistency. When an armature wears, develops a short, or burns out, the motor loses efficiency rapidly — output drops, the tool runs hot, and left unaddressed, further motor damage follows.
