6.5kw To 315kw Stamford AC Synchronous Generator Brushless Dynamo

Brushless AC generator, suitable for operation at 1500 RPM, 170V and up to 454 Volts, 0.8 pf (lag) suitable for 50 Hz, 3 phase & 1 phase, 4 wire system. The alternator is designed and built to withstand tropical conditions. The alternator generally conforms to IEC 34-1/34-2 , BS 4999/5000 and IS: 4722-2001 with enclosures rating IP 23 is the standard version, satisfying IEC 34-5/IS : 4691/DIN VDE 0530-5 requirements. The Alternator is dynamically balanced , brushless type, screen protected, revolving field, self excited, self regulated through an AVR. The alternator has the following features:

1. +- 1.0 % Voltage regulation (max.) in static conditions

2. IP: 23 protection with insulation class H

3. Permissible overload of 10% for one hour in 12 hours of operation.

The generators have been designed for use in a maximum ambient temperature of 40℃ and altitude less than 1000M above sea level.

Arranges in order all voltages may obtain from the single wide wingding ,also namely(three -phase) and 4(single -phase) reorganizes through 12 terminals may obtain.

Other special voltage can be met by Farrand company.

For 3-Phase 4 Pole alternators

Information for AVR:

We have many types of AVR,such us SX460, SX440, SX421, MX341, MX321,etc.

· The main stator provides power for excitation of the exciter field via AVR.

· Output power of exciter's rotor is input to that of mains through 3-phase full wave rectifier.

· Connected with piezoresistance for restraining surge voltage and avoiding the impact caused by short circuit or parallel synchronization loss.

· Exciter's Stator is equipped with permanent magnetic steel, it can make generator starting smoothly in any occasions.

· Voltage regulation (0.5 %) and low frequency protection, exterior voltage adjustment of SX440, MX341 and MX321 suitable for the generator with permanent magnetic generator (PMG).

Features:

1.  Any permanent magnetic alternators,providing invariable excitation on all occasions.

2.  Easy to be connected with power network or other alternators.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.

5.  Wide range of flange adaptor and single bearing coupling disc

6.  Meet leading standards.

ELECTRIC FEATURES:

Insulation

Insulation class H

All regulatory components are made up with special materials and are immersed in lacquer by peculiar tech. Varnish and colophony materials are developed to strengthen the proce for protecting the alternator work under corrosive environment.

Winings and electric features:

2/3 pitch windings design can effectively eliminate the third harmonica wave(3rd,9th,15th)of the voltage,which is the best design of UPS for nonlinear load.Connected with the network in parallel,the structure can restrain excessive currents in the midline.

A continous damp windings abates surges.The poles and gears of the windings are carefully chosen,this and the 2/3 pitch help to check the wave distortion of output voltage.

Phone interference:

THF (defined by 40th part of BS4999)<=2%.TIF(defined by ASAC50.12)<=50.

Radio interference:

Brushless apparatus and quality AVR ensure little radio interference in transmission.RFI noise filter is also avaiable.

The advantage of our material:

· The rotors and stators with 100% copper wire.

· The enamelled wire is Essex by America.

· The silicon steel sheet we use is the products of Wugang Brand,800 Series.which is the most famous manufacture of steel.And its advantage is its magnetic flux is large and its iron loss is small.

· The main frame of the alternator and lead box are made of steel,the end cover is made of high strength cast iron.

· All the components of our factory,the stator,rotor and excitation will be dipping lacquer twice.

· The rope of best nylon to be used in all the rotors and stators.We promise the security of our products,the phenomenon of ribbon burst will never happen.

· The TWB bearings are useing in our products.

· All the rotors should be tested by dynamic balance of Germany to go on test of balance. All the products should be tested by specialized Test Room.
