1, Optional permanent magnetic alternator, provide invariable
excitation in any situation.
2, Easy to be connected with power network or other alternators.
Standard 2/3pitch windings avoid excessive neutral current.
3, Dynamically balanced rotors, with single or two sealed ball
4, Simple installation and maintenance with easy access to
terminals, rotating diodes and coupling bolts.
5, Wide range of flange adaptor and single bearing coupling disc.
6, Built to conform to all leading industrial standards.
Excitation system: The main stator supplies power to exciter stator
via Automatic Voltage Regulator (AVR). The output of exciter rotor
is fed to the main rotor through a three phase full wave rectifier.
There are varistors at the both ends of the rectifier for
restraining surge voltage and avoiding the impact caused by short
circuit or parallel synchronization loss. Exciter stator is
equipped with permanent magnetic steel in order to start up the
alternator smoothly in any occasion.
Insulation class H
All wound components are made up with specialized material and
immersed in varnish by especially technology. Resin matrix material
is developed to strengthen the process and machinery intensity of
windings and revolving parts for the alternator working under harsh
Windings and electric features
Standard 2/3 pitch windings design can eliminate the triple
frequency harmonics on the voltage waveform which is the optimum
design for trouble-free supply of non-linear loads. Connected with
the network in parallel, the structure can restrain excessive
currents in the midline. A fully damp winding reduces oscillations
during paralleling. This winding, with 2/3pitch and carefully
selected pole and tooth designs, ensures very low waveform
Wiring terminal and terminal box
Standard alternator is 3 phase re-connectable to 12 ends brought
out to the terminals, which are mounted on a cover at the non-drive
end of the alternator. A sheet steel terminal box contains the AVR
and provides ample space for customer's wiring and gland
arrangements. It has removable panel easy access.
The FLD generator is available in single and double bearing
construction to meet the SAE standard, and also we can supply
All generator rotors are dynamically balanced to better than
BS6861: Part 1 Grade 2.5 for minimum vibration in operation. Two
bearing generators are balanced with a half key.
