STAMFORD copy brushless generator

STAMFORD copy brushless 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 5.Wide range of Flange adaptor and single bearing coupling disc 6.Meet leading Industry and Marine standards MECHANIC FEATURES FRAME: All industrial standard generators is IP21(NEMA1), also IP23 is optional, But rated power will decrease 5% if installed. AXIS AND KEY: All of the generator rotors pass balance test. The vibrations are lower than the minimum of BS6861 P.1, G 2.5 two bearing generator has a half-key testing balance. TERMINAL AND TERMINAL BOX: The three-field generator has 12 leads brought out to the terminals in terminal box. The terminals are put on the non drive end. The box is equipped with removable panels ENGINE ADAPTOR AND COUPLING DISC: SY-A Series generators have two kinds construction. SY-A Series single-bearing, engine adaptor: SAE0,1,2,3 and 4; Coupling discs: SAE8,10,11,.5,14 and 18 are available. SY-A Series double-bearing, engine adaptor: SAE0,1,2,3,4 and 5 are available. VOLTAGE REGULATION: Voltage regulation refers to the change of voltage from non-load to 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 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 processing and machinery intensity of windings and revolving parts for protecting the generator work under corrosive environment. WINDINGS AND ELECTRIC FEATURES: 2/3pitch windings design can effectively eliminate the third harmonicwave(3rd,9th,15th)of the voltage, which is the best design of UPS for nonlinear load. Connected with the network in parallel, the structurecan 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 high quality AVR ensure little radio interference in transmission. RFI noise filter is also available. OPTIONAL FEATURES: 1. Adaoters and drive disks 2. Single phase 3. Remote voltage adjust 4. IP23 enclosure 5. Space heaters 6. Thermistors
