The Wacker Neuson Motor Armature is a genuine OEM component designed for the EHB 7M and EHB 7/115 series electric demolition hammers. Sourced directly from Wacker Neuson, this Motor Armature is manufactured to the exact specifications of the original part, ensuring a correct fit within the motor housing of these SDS-max 115V rotary demolition hammers. Verified fitment covers the EHB 7M (), EHB 7/115 (), and EHB 7/115 () machines. Replacing a worn or failed armature with a genuine OEM part restores the motor's designed output and keeps your tool operating as intended.
Key Features
- Genuine OEM Windings and Core: — Built to the exact coil winding count, conductor gauge, and core geometry of the original, ensuring correct electrical output and torque delivery for SDS-max demolition work.
- Direct Drop-In Replacement: — Machined to match the original shaft diameter, commutator profile, and bearing seats so the armature seats correctly into the EHB 7M and EHB 7/115 motor housing without modification.
- Confirmed Fitment for EHB 7M and EHB 7/115: — Covers three machine configurations across the EHB 7 family, including the SDS-max 115V drilling and chiseling variant and both EHB 7/115 rotary demolition hammer configurations.
- Restores Full Motor Power: — A degraded armature causes loss of striking energy, overheating, and erratic performance. Installing part 5000104723 brings hammer output back to its rated level for consistent material removal.
- Electrical Safety Compliance: — As a primary current-carrying component in a 115V tool, using a genuine OEM armature ensures correct insulation class and winding integrity, reducing the risk of motor failure or electrical fault under load.
The motor armature is the rotating core of the electric motor, converting electrical energy into the mechanical rotation that drives the hammer's striking and rotary action. It works in conjunction with the field coils to generate torque; when the armature windings wear, burn, or short, the motor loses power, runs hot, or fails to start entirely. Replacing the armature with a correctly specified part restores the full energy transfer the EHB 7 series was designed to deliver on SDS-max demolition and drilling applications.
