Description
Marathon Exciter Stator 789484-0A | Genuine OEM | In stock
The Marathon Exciter Stator 789484-0A is a brand-new, genuine OEM Marathon Electric replacement component designed for reliable excitation performance in brushless synchronous generators. This exciter stator plays a critical role in voltage build-up and regulation by supplying DC field excitation to the rotating exciter assembly, ensuring stable generator output under varying load conditions.
Offered new and unused, this original Marathon Electric exciter stator is manufactured to exact factory specifications for fit, insulation integrity, and electrical performance. Using a genuine OEM exciter stator helps prevent voltage instability, excitation loss, overheating, and premature generator failure often associated with aftermarket or rewound components.
This part is commonly used on Marathon MagnaPLUS generators with 280 frame sizes. If you are unsure about compatibility with your generator model or serial number, please contact us before purchasingāour technical team is happy to help verify the correct part.

General Facts About Exciter Stators
- The exciter stator is the stationary DC field in a brushless generator system
- It provides excitation to the exciter rotor, which is rectified and fed to the main rotor
- Residual magnetism in the exciter stator allows initial voltage build-up without field flashing
- A failing exciter stator can cause low voltage, no voltage, or unstable output
- Proper resistance and insulation values are critical for long-term generator reliability
Common Applications
- Marathon Electric MagnaPLUS generators
- 280 frame size generator ends
- Industrial, standby, and prime power generator systems
ā ļø Important Note: This exciter stator is commonly used on Marathon MagnaPLUS 280 frames, but generator configurations can vary. Always confirm compatibility using your generator model and serial number or contact Joval Industrial before ordering.
Frequently Asked Questions (FAQ)
Is this a genuine Marathon Electric part?
Yes. The 789484-0A is a new, original OEM Marathon Electric exciter stator, not aftermarket or refurbished.
Is this item in stock?
Yes. This exciter stator is in stock and ready to ship.
