The Wacker Neuson Armature Motor is a genuine OEM component designed for the EH 9 and EHB 11 series electric breakers and demolition hammers. As a direct OEM part, is manufactured to the same specifications as the original unit, ensuring correct electrical characteristics, physical fit, and reliable power delivery in demanding demolition and chiseling applications. This armature motor fits an extensive range of EH 9 and EHB 11 variants across 115V and 230V configurations, including BL, BLM, and BLS tool-holder versions. Whether you're servicing a standard electric breaker or an SDS-max or Spline-drive drilling and chiseling hammer, the is the correct OEM replacement to restore full motor performance.
Key Features
- OEM Winding Specification: — Wound to the original resistance and output rating for EH 9 and EHB 11 motors, ensuring correct RPM, torque, and thermal behavior under load.
- Direct Armature Replacement: — Mounts into the motor housing the same way the original does, with matching shaft dimensions and commutator profile for straightforward installation.
- Broad EH 9 and EHB 11 Fitment: — Compatible across 115V and 230V variants including BL, BLM, and BLS tool-holder configurations, covering a wide range of electric breaker and hammer models in the EH 9 and EHB 11 families.
- Restores Full Impact Power: — A worn or shorted armature causes loss of striking energy, overheating, or complete motor failure; replacing with 5000129527 brings impact performance back to original levels.
- Electrical Safety Compliance: — Using the correct OEM armature maintains the insulation class and commutator integrity required for safe operation of mains-voltage power tools at 115V and 230V.
The armature is the rotating core of a universal electric motor. It carries the windings that interact with the stator's magnetic field to generate rotational force, which the tool's internal mechanism then converts into the hammering or chiseling action the breaker delivers. When armature windings burn out, short, or the commutator surface wears, the motor loses power, runs rough, overheats, or stops turning entirely — bringing the tool to a halt. Replacing a failed armature with the correct part is one of the most effective ways to restore an electric breaker to full working condition without replacing the entire tool.
