Brushless three-phase AC Alternator

Brushless three-phase AC Alternator HYS series (6.5-500kw) steel housing brushless three-phase A.C. synchronous alternators/generators new models designed by ourselves, alternators/generators rotor adopts with whole punching, brushless excitation, with A.V.R, low speed protect and shut down if over excitation, reduce EMI. Environment conditions: Under the following environment, the generator could run continuously altitude: not exceed 1000mair temperature: 258-313K(-15°C-40°C)Relative air humidity: not exceed 90% Features: Any permanent magnetic generators, providing invariable excitation on all occasions.Easy to be connected with power network or other generators. Standard 2/3 pitch winding restrain excessive midline current.Balanced rotor with single or two sealed ball bearings.Convenient installation and maintenance with easy access to terminals, rotating diodes and coupling bolts.Wide range of flange adaptor and single bearing coupling disc.meet leading standards. Mechanic features Frame: All industrial standard generator is IP21(NEMA1), also IP23 is an option. But rated power will decrease 5%. Marine standard generators are IP23. Air filter is an option, but rated power of generator will decrease 5% while it is installed. AXIS and KEY: All of the generator rotors should pass balance test, whose vibrations are lower than the minimum of BS686 IP.1, G2.5 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.

Electric features Insulation: Insulation class H All regulatory components are made up with special materials and are immersed in lacquer 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: 2/3 pitch windings design can effectively eliminate the third harmonic wave (3rd, 9th, 15th) of the voltage, which is the best design of UPS nonlinear load, connected with the network in parallel, the structure can restrain excessive currents in the midline. 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 available. Option features: adaptors and drive diskssingle phaseremote voltage adjustIP 23 enclosure space heatersthermistors
