ST/STC single/3 phase alternator

Driven by diesel engines to supply electricity for house-hold electric devices in towns.

(1)ST single-phase synchronous generators have been awarded the national gold medal in recognition of their superiority in quality.

    ST series generators 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.The construction of the generators is of drip-proof, salient pole rotating field self excitation and constant voltage type.The alternator is adopted with high quality electric magnetic and electrical materials. Stator insulation class B. These generators looks elegant, light and easy maintenance. IEC standard are adopted on dimension,these dimension are , these suitable for using in Australia, Europe, America and other countries with the end covers to be model B.

 (2)STC Series Three-phase A.C.Synchronous GeneratorS

The generators are widely used in town, countryside,worksites, mountain and pasture districts as electric power source for lighting purpose,they can also be used as reserved power source for emergency.

The series generators are of drip-proof with rotary field type and adopt harmonic excitation system, easy operation and maintenance.

The generators are three-phase, four-wire type, adopted 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 other voltage generators according to the customer's request.

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 within the range of 0~100% cosø=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 in  the same time, without any starting device the generator can directly start an unloaded squirrel cage induction motor.
