Generator system with integral permanent magnet generator exciter
First Claim
1. A generator system having self-buildup characteristics with an integral PMG exciter, comprising:
- housing means;
rotating means journaled in the housing means;
a main stator secured within the housing;
a rotating field magnetically coupled to the main stator and secured to the rotating means for rotation therewith;
an exciter field secured within the housing;
an exciter armature magnetically coupled to the exciter field and secured to the rotating means for rotation therewith; and
permanent magnet means disposed about a radially inner periphery of the exciter field immediately adjacent a radially outer periphery of the exciter armature for interacting therewith to provide a magnetic circuit.

Abstract
A generator system having self-build-up characteristics with an integral permanent magnet generator exciter. A rotor shaft is journalled in a housing. A main stator is secured within the housing, and a rotating field is magnetically coupled to the main stator and secured to the rotor shaft for rotation therewith. An exciter field is secured within the housing, and an exciter armature is magnetically coupled to the exciter field and secured to the rotor shaft for rotation therewith. A plurality of permanent magnets are integrally secured to a radially inner periphery of the exciter field immediately adjacent a radially outer periphery of the exciter armature.
