The ST series generators are mainly designed to serve as power generating 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 field self-excitation and constant voltage type.High quality electric magnetic and electrical materials are used in the alternator. Stator insulation is of class E(or B).Rotor insulation is of class 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.These generators are excellent in appearance and easy to maintain.Dimensions are adopted according to I.E.C standards.

The voltage of the alternator is 230V or 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.

The alternator can be coupled with a prime mover directly or through a V-belt,with 5% change 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.

The generators are to be used in town,the countryside,worksites,mountain districts 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 dripproof with totary field type and with the adoption of harmonic excitation system,that allow your easy operation and simple maintenance.

The generators ate 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(lag).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%,cosα1.0 ←→ 0.8 they give good constant voltage.After sudden cnange (increase or decrease)of load,the generators will soon return to their normal working state.

Without any starting devices the generator can directly start an unloaded squirrel cage induction motor.
