20KW THREE PHASE BRUSHLESS ALTERNATOR
YHG GENERATOR
Features:
1)Any permanent magnetic generators, providing invariable excitation on all occasions.
2)Easy to be connected with power network or other generators. Standard 2/3 pitch windings check excessive midline current.
3)Balanced rotor with single or two sealed ball bearings
4)Convenient installation and maintenance with easy access to terminals, rotating diodes and coupling bolts
MECHANIC FEATURES
Frame
All industrial standard is IP21,also IP23 is an option, but rates power will decrease 5%.
Marine standard alternator is IP22.
Balance
All of alternator rotors should pass balance test, whose vibrations are lower than the minimum of BS6861 P.1,G 2.5 two bearing alternator has a half-key testing balance
Terminal and terminal box
The three-field alternator had 12 leads brought out to the terminals in the terminal box. The terminals are put on the non drive end . The box is equipped with removable panels.
Voltage regulation
Voltage regulation refers to the change of voltage from no-load to full-load with power factor ranging from 0.8 to 1 and 3%s fluctuation of the speed of engine. Voltage is adjusted via potentiometer of AVR
