Brush Generator

The ST series generators are mainly designed to serve as power generating unit of small unit of small capacity which supply electricity for lighting purpose in ships as well as for household electric devices used in towns or villages. The construction of the generators is of drip-proof, salient pole rotating filed self-excitation and constant voltage type. The alternator inside is used with high quality electric magnetic and electrical materials. Stator insulation is of Class E (or B), rotor insulation is Class B. These generators are excellent in appearance. They are solid in construction and easy to maintain. Dimensions are adopted IEC standard; they are suitable for Australia, Europe, America and other countries if the end covers are model B. The alternators are of harmonic wave self-excitation constant voltage system and automatic voltage control excitation constant voltage system; both of them have excellent dynamic performance, convenient and reliable in operation. The voltage of the alternator is 230v or 115v (if necessary it can be 240V or 120V). The frequency is 50HZ or 60HZ its operation mode is of continuous duty. The alternator can be coupled with a prime mover directly or thorough a V-belt with 5% change of speed the prime mover under load variation of 0←→100% at a voltage of 230v or 115v 50HZ or 60HZ to get a satisfactory constant-Voltage performance.TypeOutputCurrent(A)VoltagePower factorPole numberSpeed(rpm)Series connectionParallel connectionSeries connectionParallel connectionST-228.717.4230115141500ST-33132641500ST-5521.743.541500ST-7 .57.532.665.241500ST-101043.58 741500ST-121252.5104.441500ST-151565.2130.441500ST-20208717441500INSTA LLATION SIZE AND OVERALL DIMENSION TypeOutput(kw)Installation Size(mm)Overall Dimension(mm)Weight(Kg)ABCDEFGHKabH1hL1L2gST-2KW221617889Φ328010271321 234250183854802703565ST-3KW321 617889Φ328010271321234250183854802703570ST-5KW5254254108Φ3880103316015 503102544058032541120ST-7.5KW7 .5254254108Φ3880103316015503102544058032541130ST-10KW10279203121Φ42110 123718015603392548061036545140 ST-12KW12279203121Φ42110123718015603392548061036545155ST-15KW153182281 33Φ481101442.52001960378305406 6040051.5192ST-20KW20318228133Φ481101442.520019603783054066040051.5202 The generators are to be used in town, the countryside, worksites, and mountain and pasture lands as a electric power source for lighting purpose, it can also be used as a reserved power source for emergent case. The generators are of drip-proof with rotary filed type and with the adoption of harmonic excitation system, which allow you operate easily and maintain simply. The generators are of three-phase four-wire type, making use of star connection with neutral point. The rated line voltage is 400v, phase voltage 230v, frequency 50HZ, power factor 0.8 (Lagging). It can provide 60HZ and the other voltage's generator according to necessary. They can be coupled with a prime mover directly or through V-belt making right or reverse continuous rotation at the rated speed. When the revolution slip of prime mover is 3% and load varies in the range of 0←→100% cos Φ1.0-0.8 they give good constant voltage. After sudden change (increase or decrease) of load, the generators will soon return to their normal working state. Without any starting devices the generator can directly start and unloaded squirrel cage induction motor.TypeOutput(KW)Output(KVA)Current(A)Pole numberSpeed (rpm)STC-333.85.441500STC-556.3941500STC-7.57.59.413.541500STC-101012. 518.141500STC-12121521.741500S TC-151518.827.141500STC-20202536.141500STC-303037.554.141500STC-404050 72.241500STC-505062.590.241500 TypeOutput(KW)Installation Size (mm)Overall Dimension(mm)Weight(kg)KWKVAABCDEFGHKabH1hL1L2gSTC-333.821617889Φ32801 0271321334250184004802703570ST C-556.3254254108Φ3880123316016503102545058032541120STC-7.57.59.4254254 108Φ38801233160165031025580580 32541130STC-101012.5279203121Φ42110123718016603392559061036545140STC-1 21215279203121Φ421101237180166 03392549061036545155STC-151518.8318228133Φ4811014452002060378305006604 0051.5192STC-202025318228133Φ4 8110144520020603783050066040051.5202STC-303037.5356286149Φ601401853225 20654213265077045264257STC-404 050356286149Φ60140185322520654213265077045264290STC-505062.5356311149Φ 601401853225206542132650810452 64344 ModelSingle-phase 230v 50HZ/min COS Φ=1.0Rated outputRated Voltage (V)Rated Currant(A)Welding voltage under (V)Welding Current(A)Continuous rate under load(%)Current adjustment range for welding(A)KWKVASD-55523021.7＜801604070-200SD-7.57.57.523032.6＜80200408 0-240SD-10101023043.5＜80250401 00-300SD-12121223052.2＜8030040140-320ModelThree-phase 400v 50HZ 1500r/min COS Φ=0.8SD-5554009＜801404060-160SD-7.57.57.540013.5＜801804070-200SD-10101 040018.1＜802254080-280SD-12121 240021.7＜8028040100-300 url: http://www.fjtjmotor.com
