ST series alternators/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 alternators/generators is of drip-proof, salient pole rotating field self-excitation and constant voltage type. The

alternators/generators inside is used with high quality electric magnetic and electrical materials. Stator insulation is of Class E (or B). rotor

insulation is of Class B. These alternators/generators are excellent in appearance. they are consolidate in construction and easy to

maintain. Dimensions are adopted IEC standard, they are suitable for Australia, Europe, America and other countries if the end covers are

model B.

The alternators/generators 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.

The voltage of the alternators/generators is 230V or 115V (if necessary it can be 240V or 120V). the frequency is 50Hz or 60Hz its

operation mode is of continuous duty.

The alternators/generators can be coupled with a prime mover directly or through a V-belt. with 5% change of speed 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.
