ST/STC Series generators

Introduction
ST Series generators are mainly designed to serve as power generating unit for lighting purpose in ships, towns or villages and house-hold electric appliances.
The construction of the generators is drip-proof type, IP21, salient-pole rotating field self excitation and constant voltage type. The generator interior is made of high quality magnetic and electrical materials. Insulation for stator and rotor is class B or F.
STC Series generators are used in town, countryside, worksites, villages and pastures as electric power source for lighting purpose and three phase AC power supply, it can also be reserved as emergence power source.
The generators are drip-proof with rotary field type, IP23, Insulation Class: B or F, adopting harmonic excitation system, safe and reliable using, easy operation and maintenance.

The generators 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.
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 changes 3% or so and load varies in the range of 0~100% COS 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.
The generators are made as per standard JB/T8981-1999. And in conformity to IEC34-1.
