50Hz Factory Use 20Kw Three Phase 220V Ac Dynamo

1.Electrical Character
Excitation system: The main stator supplies power to exciter stator via Automatic Voltage Regulator (AVR).The output of exciter rotor is fed to the main rotor through a three phase full wave rectifier. There are varistors at the both ends of the rectifier for restraining surge voltage and avoiding the impact caused by short circuit or parallel synchronization loss. Exciter stator is equipped with permanent magnetic steel in order to start up the alternator smoothly in any occasion.

2.Windings and electric features
Standard 2/3 pitch windings design can eliminate the triple frequency harmonics on the voltage waveform which is the optimum design for trouble-free supply of non-linear loads.

3.Shaft & key
All generator rotors are dynamically balanced to better than BS6861: Part 1 Grade 2.5 for minimum vibration in operation. Two bearing generators are balanced with a half key.
