ABSTRACT:
A starter-motor, and alternator-generator apparatus for an internal combustion or gas turbine engine wherein the major electro-magnetic circuit of the apparatus is utilized for both the starting and generating functions is disclosed. The rotor may have two windings on it, a main rotor winding that acts as both a starter armature winding and an alternator field winding, and a small exciter armature winding. For slip ring machines the exciter is eliminated. The main rotor winding is wound in progressive simplex lap. The exiter armature or slip rings are connected to this winding at the equalizer connections through a rectifier and automatically activated switch circuit. During starter-motor operation, the main rotor winding is connected in series with its starter field winding through a commutator in a conventional series connected DC machine, and the exciter-armature winding or slip rings are disconnected from the main rotor winding. During alternator-generator operation, the brushes are lifted off the commutator and the exciter-armature winding or slip rings are connected to the main rotor winding.
