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.
Windings & Electrical Performance:
All generator stators are wound to 2/3 pitch. This eliminates triplen (3rd, 9th, 15th …) harmonics on the voltage waveform and is found to be the optimum design for trouble-free supply of non-linear loads.
The 2/3 pitch design avoids excessive neutral currents sometimes seen with higher winding pitches, when in parallel withthe mains. A fully connected damper winding reduces oscillations during paralleling. This winding, with the 2/3pitch and carefully selected pole and tooth designs, ensures very low waveform distortion.
Terminals & Termianl Box:
Standard generators are 3-phase reconnectable with 12ends brought out to the terminals, which are mounted on a cover at the non-drive end of the generator. A sheet steel terminal box contains the AVR and provides ample space for the customers' wiring and gland arrangements. It has removable panels for easy access.
