ABSTRACT:
In a synchronous dynamoelectric machine having a pilot exciter which energizes a brushless exciter, voltage regulation and forcing excitation are provided by a plurality of field coils which are disposed upon selected ones of a plurality of permanent magnets carried by the rotor of the pilot exciter. The field coils are connected together to constitute a field winding and are electrically connected to receive direct current excitation from the output of a rotating rectifier assembly through coupling means, such as a direct current regulator. In operation, the regulator is responsive to changes in the current flowing through the field winding of the synchronous dynamoelectric machine and provides a direct current output signal to the permanent magnet field winding to increase the magnetic field strength of the associated permanent magnets.
