ABSTRACT:
The problem of providing field power to a stationary main generator rotor is addressed such that it can be used as a synchronous or brushless dc motor. To that end, a dynamoelectric machine performs the dual-functions of an exciter generator and a rotating transformer integrated into a single unit (14). The heads (64) of the stator salient poles (60) include pole slots (68) for a primary transformer winding (34) for the rotating transformer, while the rotating armature winding (36) serves as the transformer secondary. To assist in starting the engine (10), external ac power (42) is applied to the primary transformer windings (34), coupled to armature windings (36), and rectified (44) to develop dc field power for the main generator (12).
