ST/STC series synchronous generators

ST series 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 this generator
is of drip-proof, salient pole rotating field self-excitation and
constant voltage type. The alternator inside is made of high quality electric
magnet and electric materials. 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 which have excellent dynamic characteristic
performance, convenient and reliable operation. The voltage of the
alternator is 240V or 120V if necessary, the frequency is 50Hz or 60Hz.
Its operation mode is of continuous duty. 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 from 0 to 100% and from 100% to
0, at a voltage of 230V or 115V, 50Hz or 60Hz to get a satisfactory
constant-voltage performance.

STC series are to be used in towns, countryside, work sites, mountain
districts and lands as an electric power source for lighting purpose. It
can be also used as a reserved power source for emergent case. These
generators are of drip-proof with rotary field type and with the adoption of
harmonic excitation system, which allow your easy operation and simple
maintenance. The generators are of three-phase four-wire type, making
use of star connection. The rated line voltage is 400V, phase voltage is
230V, frequency is 50Hz, power factor is 0.8 lag. They can be coupled
with a prime mover directly or through a 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 from 0 to 100% and from
100% to 0, cosΦ1.0 - 0.8 and cosΦ0.8 - 1.0. They give good constant
voltage. After sudden change (increase or decrease) of load, generators
will soon return to their normal working state. Without any stating
devices generators can directly start an unloaded squirrel cage insulation
motor.
