ST Series Single-phase A.C. Synchronous Generators

The ST series generators are mainly designed to serve as the power generating unit of small capacities which supply electricity for lighting purposes on ships as well as for household electric devices used in towns and 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 electro-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 consolidated 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-ex-citation constant voltage system and automatic voltage control excitation constant voltage system. They have excellent dynamic performance characteristics and they are convenient and reliable in operation．

The voltage of the alternator is 230V or 115V (If necessary it can be 240V or 1 20V). 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 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．
