Three phase electric dynamo generator are to be used in town,the countryside,worksite,mountain and pasture lands as a electric power source for lighting purpose,It can also be used as a reserved power source for emergent case.The alternator sare of drip-poof with rotary field type and with the adoption of harmonic excitation sysem,that allow your easy operation and simple maintenance.The alternators are of three-phase four wire type,making use of star connection with neutral point.The rated line voltage is 400v,phase voltage is 230v.frequency 50Hz.it can provide 60hz and the other voltage's alternators according to necessary.They can be coupled with a prime mover directly or through V-belt making right or reverse continuous rotation at the rated speed.when the revolution slip of prime mover is 3% and load varies in the range of 0-100%,cosβ1.0-0.8 they give god constant voltage.After sudden change(increase or decrease)of load.The alternators will soon return to their normal working state.without any starting devices and it can directly start an unloaded squirrel cage induction motor.
