The Wacker Neuson Exciter Stator is a genuine OEM Exciter Stator designed for the G25, G50, G70, and G85 mobile generator series, as well as LTW20Z light tower models. As a direct OEM replacement sourced through Wacker Neuson's authorized parts program, this component is manufactured to the same specification as the original part installed at the factory. Broad fitment coverage spans skid-mounted, cold weather, extended run tank, and custom configurations across multiple Tier 4 emission levels, making this a single part solution for a wide range of fleet equipment.
Key Features
- Genuine OEM Electrical Output Spec — Wound and rated to the original design specification, ensuring correct excitation voltage output and stable generator performance across the full load range.
- Drop-In Installation — Matches the original stator housing dimensions, winding configuration, and terminal connections for a straightforward swap with no machining or adapter work.
- Wide Fleet Coverage — Fits G25, G50, G70, and G85 mobile generator series plus LTW20Z-1 and LTW20Z-3 light towers, covering skid-mounted, cold weather, extended run, and custom variants across Tier 4 Interim and Tier 4 Final configurations.
- Restores Stable Voltage Regulation — A worn or failed exciter stator causes erratic output voltage, load instability, and potential generator shutdown; replacing it with a correct OEM unit restores steady, regulated power delivery.
- Electrical Safety Compliance — Built to OEM insulation class and winding standards, reducing the risk of winding breakdown, overheating, or arcing that can damage downstream generator components or connected equipment.
The exciter stator is a stationary winding within the generator's excitation system that produces the magnetic field used to induce current in the exciter rotor. This current is then rectified and supplied to the main rotor field winding, which ultimately drives the generator's AC output. When the exciter stator degrades — through insulation breakdown, winding failure, or physical damage — the generator loses the ability to self-excite, resulting in low or absent output voltage even when the engine is running at the correct speed. Replacing the exciter stator with a genuine OEM part is the most direct way to restore full, stable power output to the machine.
