Abstract
A starter/generator mechanically coupled to a gas turbine transmission housing is disclosed. The starter/generator includes a generator with a rotor forming a field winding and a stator forming an armature, and an energizer with a stator forming a field winding and a rotor forming an armature connected to the generator field winding. The generator rotor and the energizer rotor are mounted on a common shaft with a transmission housing gear wheel, on either side of the gear wheel.
Claims23
An assembly comprising
- a gas turbine transmission housing;
- and
- at least one starter/generator mechanically coupled to the transmission housing, wherein
- the transmission housing comprises a gear train with several gear wheels,
- the starter/generator comprises a generator with a rotor forming a field winding and a stator forming an armature and an energizer with a stator forming a field winding and a rotor forming an armature connected to the generator field winding, and
- the generator rotor, the energizer rotor and a gear wheel engaged in the transmission housing being mounted on a common shaft with the generator rotor being located on a first side of said gear wheel and the energizer rotor being located on a second side of said gear wheel, opposite said first side, and the generator rotor and the energizer rotor being driven in common by said gear wheel.
A starter/generator module which can be integrated in a transmission housing of a gas turbine, comprising:
- a generator with a rotor forming a field winding and a stator forming an armature;
- an energizer with a stator forming a field winding and a rotor forming an armature connected to the generator field winding;
- a gear wheel;
- and
- a shaft on which the generator rotor and the energizer rotor are mounted in common with the gear wheel,
- wherein the generator rotor is located on a first side of the gear wheel, the energizer rotor is located on a second side of the gear wheel, opposite the first side, and the generator rotor and the energizer rotor are driven in common by the gear wheel.
