(under subclass 63) Subject matter wherein the magnetomotive force of at least one field winding is opposed to the magnetomotive force of at least one other field winding.
(1) Note. Where the generator includes a plurality of field windings, some of which are opposed and others aid, the subject matter is found in this subclass.
