ABSTRACT:
A brushless three-phase current generator having a fed-back, controllable device for self-excitation and automatic control of the energizing current, said device comprising controllable means for deriving from the generator output part of the output voltage and the load current of the generator and the vectorial combination and supply thereof to a multi-phase rectifier whose output is connected to a stationary d.c. energizing winding of an excitor, the rotating multi-phase winding of which enables the rotating field winding of the generator through a commonly rotating rectifier, wherein the synchronous reactance of the multi-phase winding of the excitor at the frequency corresponding to the nominal speed is achieved, which is greater than the equivalent impedance of the generator field winding.
