Obviously, two mmfs act on the d-axis of a salient-pole synchronous machine i.e. field m.m.f. and armature m.m.f. whereas only one m.m.f., i.e. armature mmf acts on the q-axis, because field mmf has no component in the q-axis. The magnetic reluctance is low along the d-axis and it is high along the q-axis.
