STC Series three-phase a.c. synchronous generators

STC Series three-phase a.c. synchronous generators are mainly designed to serve as power generating unit for lighting purpose in villages , towns, and house-hold electric appliances or standby power.The construction of the generators are salient-pole rotating field , self excitation with third-harmanic . The generator interior is made of high quality magnetic and electrical materials, and easy to maintenance. The characteristic of generators see as the followings: 1.The generators are designed as per standard JB/T3320.2-2000. And in conformity to IEC34-1. 2.Insulation is class B or F, drip-proof type is IP21, 3.Tight in construction for casting frame; If our customers ask for steel constuction,we can meet . 4.The generators are three-phases with output four terminals, connectiong for the star connection, 400V rated L-L voltage, 230V rated L-N voltage, 50Hz, 0.8P.F.。If our customers ask for 60Hz or diferenent voltage, we can meet . 5.Generally the generators are two-bearing comstuction, also can produce for single-bearing constuction; They can be coupled with engine s by leather belt, and can ratote in two different direction. 6.The steady voltage regulation of generators are good in 3% speed variation, load from no-load to full-load and power factor from 0.8 to 1.0。 7.The voltage regulation of generators are excellent, and the capability for directly-starting motor also is fine。
