AUXILIARY WINDING FOR A GENERATOR

摘要

An auxiliary winding for use in an engine-driven generator system is disclosed. The auxiliary winding is separate from but resides with the main winding in the stator slots of an alternator in the generator system. The auxiliary winding is configured to utilize the fundamental component of the flux in the airgap of the alternator along with selected spatial harmonic components to provide power to an automatic voltage regulator during all operating conditions.

主权项

1. An alternator for a generator system, comprising:
a rotor having an excitation winding; a stator having a plurality of slots, wherein a main winding and an auxiliary winding are each wound in the plurality of slots; and an airgap defined between the stator and the rotor, wherein the auxiliary winding includes a plurality of turns of wire, each turn wound in a first direction in a first slot selected from the plurality of slots of the stator and in a second direction in a second slot selected from the plurality of slots of the stator and wherein each of the plurality of turns of wire are wound in the plurality of slots according to a distribution function, wherein the distribution function is defined to couple the auxiliary winding to a fundamental component and a desired spatial harmonic component selected from a plurality of spatial harmonic components of a magnetic flux generated in the airgap and wherein the distribution function is defined to minimize coupling of the auxiliary winding to the plurality of spatial harmonic components of the magnetic flux other than the desired spatial harmonic component.
