Power Generation Plants: Essential for maintaining the constant 50/60Hz frequency required in diesel and gas generator sets for grid stability. Marine Propulsion: Used in large ship engines to prevent overspeeding when the propeller leaves the water in rough seas. Petrochemical Refineries: Employed in steam turbine drives that power high-capacity centrifugal compressors and pumps. Heavy Rail & Locomotive: Utilized in diesel-electric locomotives to synchronize engine output with the traction motor demands. Industrial Mining Operations: Critical for the large-scale crushers and grinders that experience massive, sudden torque spikes.
