ABSTRACT:
Alternators employing magnetic commutation, methods of manufacturing the alternators and wireless communications infrastructures employing the alternators. In one embodiment, an alternator includes: (1) a stator having 4n alternating field and armature poles extending axially along and projecting from an inner surface thereof, n being a positive integer, the field poles having field windings disposed thereabout to form alternating North-South magnetic polar regions and the armature poles having armature windings disposed thereabout to allow conduction of electric power from the armature poles, (2) a rotor, disposed within and journalled for rotation relative to the stator, having 2n axial magnetic passive regions, each of the passive regions being of a circumferential width magnetically to bridge one of the armature poles and only one of the field poles and (3) an exciter, coupled to the stator, that provides a controlled level of DC excitation to the field poles to regulate an output of the alternator.
