The Wacker Neuson Rotor 115 is a genuine OEM Rotor 115 designed for the M2000 series electrical power units, including the M2000/120, M2000/115/15A, and M2000/120/GFCI variants used with internal concrete vibrators. As a factory-sourced component, the meets the original design specifications for these drive units, ensuring correct electromagnetic performance within the motor assembly. This rotor is confirmed to fit multiple M2000 configurations — including UL and non-CUL variants — making it the right choice for operators servicing a range of M2000 power units in the field.
Key Features
- Genuine OEM Electromagnetic Spec — Factory-wound to the original magnetic tolerance for the M2000 motor, ensuring correct rotational output and consistent vibrator frequency.
- Direct Drop-In for M2000 Power Units — Engineered to seat and balance within the M2000 motor housing exactly as the original, with no reworking of the stator cavity or shaft alignment required.
- Broad M2000 Series Coverage — Fits M2000/120, M2000/115/15A, M2000/120/nonCUL, M2000/120/GFCI, and M2000/120/UL electrical power units in a single part number.
- Restores Full Vibrator Drive Performance — A worn or damaged rotor causes erratic motor speed and reduced vibration output; replacing with OEM part 5000078972 brings the drive unit back to full operating specification.
- Electrical Safety Integrity — As a rotating electrical component inside a concrete vibrator power unit, correct rotor specification is critical to safe motor operation and protection of downstream GFCI and UL-listed circuit elements.
The rotor is the rotating core of the electric motor inside the M2000 power unit. It works in conjunction with the stator to generate the rotational force that drives the internal concrete vibrator head, producing the vibration needed to consolidate fresh concrete and eliminate air voids. When a rotor wears, becomes damaged, or loses magnetic integrity, the motor loses torque and speed consistency — resulting in reduced vibration amplitude at the head, uneven concrete consolidation, and potential overheating of the motor assembly.
