DISTRIBUTED ARCHITECTURE FOR A GAS-TURBINE STARTER/GENERATOR
First Claim
1. A starter/generator for a gas turbine, the starter/generator comprising a generator with a rotor forming a primary magnetic circuit and a stator forming a secondary magnetic circuit, and an exciter with a stator forming a primary magnetic circuit and a rotor forming a secondary magnetic circuit, the starter/generator comprising:
- a first module or generator module comprising a first casing, the generator housed in the first casing and a first shaft constrained to rotate with the rotor of the generator projecting from the first casing and carrying a first mechanical coupling member;
a second module or exciter module, comprising a second casing, the exciter housed in the second casing, and a second shaft secured to rotate with the rotor of the exciter, the second shaft being distinct from the first shaft, projecting from the second casing, and carrying a second mechanical coupling member; and
an electrical connection comprising a rectifier and at least one connector for connecting the secondary circuit of the exciter to the primary circuit of the generator.

Abstract
A gas-turbine starter/generator comprises: a generator module comprising a first casing, a generator housed in the first casing, and a first shaft constrained to rotate with the rotor of the generator, projecting from the first casing, and carrying a first mechanical coupling member; an exciter module, comprising a second casing, an exciter housed in the second casing, and a second shaft distinct from the first shaft, constrained to rotate with the rotor of the exciter, projecting from the second casing, and carrying a second mechanical coupling member; and an electrical connection comprising a rectifier and at least one connector for connecting the secondary circuit of the exciter to the primary circuit of the generator. The mechanical coupling members are coupled to a common gearwheel or to respective different gearwheels of a gearbox of the gas turbine.
