we are a stamfod copy alternator manufacturer in Wuxi China. 
 
AC synchronous generators
Growth energy AC synchronous generators are brushless 4 pole, self- 
ventilated machines, producing 8.1KVA ~1000KVA 50HZ/60HZ ac generators. The
generators are available in one or two bearing configurations, and are
designed and built using proven technology in accordance with IEC 600341-1
& -2 requirements, BS4990 & 5000, NEMA MG12006, CSA & C/UL, ad CE. 

Key Features
_Advanced automatic voltage regulator (AVR) control for trouble-free
operation under the most demanding condition. 
_Easy paralleling with mains or other generators. 
_Standard 2/3 pitch windings avoid excessive neutral currents. 
_One slot stator skewing further reduces harmonics. 
_Dynamically balanced rotors, with sealed-for-life ball bearings and
single or two-bearing construction. 
_Simple installation and maintenance, with easy access to terminals, 
rotating diodes and coupling bolts. 
_Built to conform with all leading industrial standards. 
_Wide range of Flange adaptor and single bearing coupling disc. 
_Exciter's Stator is equipped with permanent magnetic steel. It can make
generator starting smoothly in any occasions.
