  • Rotating Diode

    Our rotating rectifier diodes are specifically designed for use in the brushless excitation systems of synchronous generators (alternators). Mounted directly on the rotating part of the rotor, these diodes convert AC to DC within the exciter rotor circuit, delivering reliable field current to the main generator rotor. Built to withstand high-speed rotation, mechanical stress, and extreme vibration, they ensure stable and durable excitation performance under demanding operating conditions.


    Key Features:

    • Converts AC to DC in rotating exciter circuits

    • Designed for high-speed rotor operation

    • High mechanical strength for centrifugal force resistance

    • Vibration-resistant construction for long-term reliability

    • Stable performance under continuous rotation

    • Compact design for integration in limited rotor space

    • High thermal and electrical durability

    • Long service life in harsh generator environments


    Applications:

    • Brushless excitation systems in synchronous generators

    • Power plant alternators

    • Marine alternators

    • Industrial generators

    • Large-scale backup generator systems

    • Rotating exciter assemblies in hydro and thermal power stations
