ST series single-phase a.c.synchronous generator
NEXT YD Series Multi-Speed Electric Motor Back List PRE 2.5QF-3 GASOLINE GENERATOR
 

The ST series generators are mainly designd 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. The alternator 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 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 are of harmonic wave self-excitation constant voltage system and automatic voltage control excitation constant voltage system, both of them have excellent dynamic cha-racterstic performance, convenient and reliable in operation.

The voltage of the alternator 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 alternator can be coupled with a prime mover directly or thorough 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.
