The invention relates to electrical equipment for electric trains. A converter consists of a synchronous generator (2) having an armature winding (3) and an excitation winding (4), a drive engine having an armature winding (5) positioned in slots (6) of a rotor (7), and a stationary inductor (8) on which are positioned an independent excitation winding (9) and a consecutive excitation winding (10). A rotor of the generator and a rotor of the drive engine are affixed to the same shaft (11). Outputs of the armature winding (5) are connected to a collector (12) which is located on the shaft of the rotor (7) near one end of the rotor, and are intended for connecting to a direct current voltage source by means of brushes (13). The rotor (7) of the drive engine is provided with a second collector (15) which is positioned on the shaft (11) near the second end of the rotor (7), sections of the winding (5) are made of two identical coils (16, 17) which are oppositely stacked in the slots (6) of the rotor (7) (Fig. 1), and the outputs of each of the coils (16, 17) are connected to a collector (12, 15) located on a corresponding end of the rotor (7). In each section of the winding (5), the coils (16, 17) are connected in series by means of the collectors (12, 15) and the brushes (13), with a shift of 180 electrical degrees. Currents, which pass through the conductors of the coils (16, 17) stacked in each slot (6), move in the same direction. |
