涡轮引擎起动发电机和对其控制的方法
摘要：
一种涡轮引擎起动发电机，包括：主电机(20)，其具有定子和带有缠绕的转子电感器和形成一笼的减震棒的转子；和励磁机(30)，其具有定子电感器和具有转子绕组的转子，所述转子绕组通过一旋转整流器(36)与所述主电机的转子电感器相连。在起动阶段的第一步骤过程中，通过将交流电引入主电机的定子绕组，主电机(20)以异步电动机模式操作，仅利用所述减震棒产生一起动扭矩，主电机的转子电感器对产生起动扭矩不起较大作用。在起动阶段的随后第二步骤过程中，通过将交流电引入主电机的定子绕组，同时通过将直流电经所述励磁机(30)引入主电机的转子电感器，主电机(20)以同步电动机模式操作，当轴的转速到达一预定值时，执行从起动阶段的第一步骤到第二步骤的改变。
摘要（英）：

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.
