ST/STC Series single/three phase ac alternator
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 pitches 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
ST SINGLE PHASE ALTERNATOR
1) The ST series alternator are mainly designed to serve as power generating unit of small capacity, which supply electricity for lighting purpose in ships, for house-hold electric devices used in towns or villages.
2) The construction of the generators is of drip-proof, salient pole rotating field self excitation and constant voltage type. The alternator interior is used with high quality electric magnetic and Electric materials. Stator insulation is class B.
3) These generators are elegant in appearance, tight in construction and easy maintenance. IEC standard are adopted on dimension, these dimension are suitable for using in Australia, Europe, America and other countries with the end covers to be model B.
4) The alternators are of harmonic wave self-exciation constant voltage system and automatic voltage control excitation constant voltage system, have Excellent dynamic performance, convenient and reliable in operation. These generators are excellent in appearance and easy to maintain. Dimensions are adopted according to i. e. C Standards.
5) The voltage of the alternator is 230V of 115V, the frequency is 50Hz. Its operation mode is of continuous duty. It can provide 60Hz and the other voltage's generator according to necessary.
6) The alternator can be coupled with a prime mover directly or through a V-belt, with 5% change of speed of 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.
STC THREE PHASE ALTERNATOR
1) STC series AC alternators are to be used in town, countryside, worksites, mountain and pasture as electric power source for lighting purpose, it can also he used as reserved power source for emergent case using.
2) The AC alternators are of drip proof with rotary field type and adopt harmonic excitation system, easy operation and maintenance.
3) STC AC alternators are three-phase, four-wire type, adopting star connection with neutral point. The rated line voltage is 400V, phase voltage 230V, frequency 50Hz. Power factor 0.8(lag). We can provide 60Hz and the other voltage's generator according to the customer's request.
4) 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 rotation speed of prime mover changs 3% or so and load varies in the range of 0~100% cos j 0.8~1.0, the generators offer constant voltage, when sudden change (increase or decrease) of load, the generator will soon return to their normal working state, at the same time, without any starting device the generator can directly start an unloaded squirrel cage induction motor.
