Title:
TURBINE ENGINE STARTER/GENERATOR, AND METHOD FOR THE CONTROL THEREOF
Document Type and Number:
WIPO Patent Application WO/2011/051598
Kind Code:
A3
Abstract:
A turbine engine starter/generator includes a main electrical machine (20), having a stator and a rotor (22) having a wound rotor inductor and shock-absorbing bars forming a housing, and an exciter (30), having a stator inductor and a rotor having rotor windings connected to the rotor inductor of the main electrical machine via a rotating rectifier (36). During a first step of the starting phase, the main electrical machine (20) is controlled, in asynchronous motor mode, by means of injecting an alternating current into the stator windings thereof, a starting torque being created by means of the single shock-absorbing bars without any particular contribution by the rotor inductor of the main electrical machine to the generation of the starting torque. During a second step following the starting phase, the main electrical machine (20) is controlled, in synchronous motor mode, by means of injecting an alternating current into the stator windings thereof while supplying continuous current to the rotor inductor of the main electrical machine via the exciter (30), the transition from the first step to the second step of the starting phase being controlled when the rotation speed of the shaft reaches a predetermined value.
