The Wacker Neuson Rotor Assembly is a genuine OEM component designed for the EH 27/115 and EH 27/120 Low Vib electric breakers. As a direct factory replacement, it is sourced and validated to meet Wacker Neuson's original build specifications, ensuring the motor restores to its designed output characteristics. This part fits both the standard 110V EH 27/115 and the EH 27/120 Low Vib variant, making it the correct choice for technicians servicing either model in the field or workshop.
Key Features
- Genuine OEM Electrical Integrity — Manufactured to the original winding and lamination specification, ensuring correct motor output and consistent power delivery under load.
- Drop-In Motor Replacement — Engineered to seat directly into the existing motor housing without modification to end bells, brushes, or bearing seats.
- Confirmed Fitment — Verified for the EH 27/115 electric breaker (110V) and the EH 27/120 Low Vib electric breaker.
- Restored Breaking Power — A worn or failed rotor causes loss of torque, overheating, and erratic tool operation; replacing it returns the breaker to full impact consistency and chisel control.
- Electrical Safety Compliance — As a core motor component on a mains-powered electric breaker, using a genuine OEM rotor maintains correct insulation class and electrical rating, supporting safe operation at rated voltage.
The rotor is the rotating core of the electric motor inside the EH series breaker, working in conjunction with the stator to convert electrical energy into the rotational force that drives the hammer mechanism. When the rotor windings degrade or the laminations become damaged — through overloading, moisture ingress, or normal wear — the motor loses efficiency, runs hot, and can no longer deliver consistent impact energy to the chisel. Replacing the rotor assembly restores full motor function and ensures the breaker operates safely at its rated voltage and impact output.
