Drip Proof Three Phase Brushless Ac Generator With Structure Alternator
Our Features :
1) four-pole brushless self-excited, drip proof structure.
2) The stator, wound in 2/3 pitch, can effectively inhibit the waveform distortion of the output voltage, and reduce the heat of the magnetic field.
3) The rotor will reduce the voltage deviation and temperature rise under non-constant load with the assistance of dynamic balance and the impeccable damper before assembly.
4) The output power of the exciter rotor will supply the main rotor through a three-phase full-wave bridge rectifier, which is protected by a surge suppressor, in order to avoid damage from the shock caused by the out-of-step phase on short circuit or in parallel.
5) Automatic Voltage Regulator has the characteristics to protect he automatic load-shedding function of an engine. It will quickly reduce the output voltage of a genset if the engine speed is lower than the normal speed, which helps the engine or prime mover recover rapidly in the sudden heavy load.

Voltage Regulator:
SX460 AVR - STANDARD
With this self excited control system the main stator supplies power via the Automatic Voltage Regulator
(AVR) to the exciter stator. The high efficiency semiconductors of the AVR ensure positive build-up from initial low levels of residual voltage. The exciter rotor output is fed to the main rotor through a three phase full wave bridge rectifier. This rectifier is protected by a surge suppressor against surges caused, for example, by short circuit.
AS440 AVR
With this self-excited system the main stator provides power via the AVR to the exciter stator. The high efficiency semi-conductors of the AVR ensure positive build-up from initial low levels of residual voltage. The exciter rotor output is fed to the main rotor through a three-phase full-wave bridge rectifier. The rectifier is protected by a surge suppressor against surges caused, for example, by short circuit or out-of-phase paralleling. The AS440 will support a range of electronic accessories, including a 'droop' Current Transformer(CT) to permit parallel operation with other ac generators.
