Abstract
In an a.c. generating means exciting method, the exciting windings are wound on the stationary core on which the armature winding has been wound, in such a manner that the exciting windings are delta-connected to one another with the two ends open, and the zero phase current obtained from the two open ends of the delta-connected exciting windings and the phase current obtained from the exciting windings are combined and subjected to rectification to provide a direct current which is utilized to excite the field winding, whereby the field control is carried out in response to the increasing load current and the transient characteristic of the a.c. generating means is improved.
