FMW generator alternator are so designed
that they obviously eliminate triple harmonics on the voltage waveform and are
optimally designed for trouble-free supply of non-linear loads. The brushless generator is invented to
avoid excessive neutral currents when in parallel with the mains. A fully
connected damper winding reduces oscillations during paralleling. This winding
with the pitch and carefully selected pole and tooth designs ensures very low
waveform distortion. The main stator supplies power via the Auto Voltage
Regulator (AVR) unit to the exciter stator with a self-excited control system.
This exciter rotor output is fed to the main rotor through a three phase full
wave bridge rectifier, which is protected by a surge suppressor against surges
caused by short circuit. The insulation system or temperature-rise of the
alternator is Class H.
