Product Description
Generator Rotor
General Function
Key Features
-
Advanced Internal Cooling: The rotor employs a highly efficient internal cooling "sub-slot radial" ventilation method. The end coils are designed with two air intake paths, ensuring uniform temperature distribution, minimal overall temperature rise, and reduced line losses.
-
Premium Conductor Materials: The rotor coils are manufactured from advanced silver-containing copper bars. This specialized material provides exceptional creep resistance, maintaining structural and electrical integrity under extreme centrifugal stresses.
-
Optimized Aerodynamics: Equipped with high-efficiency propeller-type fans located at both ends of the rotor, just outside the center ring. These fans are thermally mounted onto the shaft and feature adjustable blade installation angles, locked into the optimal position for maximum ventilation performance.
-
Rigorous Vacuum Balancing: To guarantee ultra-smooth, vibration-free operation at operating speeds, every rotor undergoes strict testing and calibration in our state-of-the-art vacuum dynamic balancing machine.
-
Broad Capacity Range: We manufacture and support generator rotors for a vast array of unit sizes, ranging from 12 MW up to 660 MW, accommodating air-cooled, water-cooled, and hydrogen-water-cooled configurations.

Frequently Asked Questions (FAQ)
-
How does the internal cooling system of the rotor work? Our rotors utilize an advanced "sub-slot radial" ventilation system. The end coils feature a dual air intake design that evenly distributes the cooling medium, ensuring uniform temperatures and preventing localized overheating.
-
Why do you use silver-containing copper for the rotor coils? The massive centrifugal forces generated during high-speed rotation can cause standard copper to deform over time. Silver-containing copper bars offer superior creep resistance, ensuring the coils maintain their precise shape and electrical efficiency over the generator's lifespan.
-
How do you guarantee the rotor will not cause turbine vibration? Every generator rotor we produce is rigorously tested in a specialized vacuum dynamic balancing chamber. This ensures perfect weight distribution across the rotor's axis, eliminating vibration issues before the component ever reaches your facility.
