STC 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 F (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% chance 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.
