摘要： The present disclosure relates to a synchronous electrical machine (1) that is adapted to alternately work as an electric generator or as an electric motor. The synchronous electrical machine (1) comprises a rotor (2), that is provided with a main rotor winding (25) configured to cooperate with a main stator winding (15), and an excitation system (3) for exciting the main rotor winding (25) to a production of a main rotor magnetic field. The excitation system (3) comprises a first exciter (31), which in the specific case is of conventional type in direct current, and a second exciter (32), which in the specific case is in alternating current. The first exciter (31) is operational when the synchronous electrical machine (1) works as electric generator and it is non-operational when the synchronous electrical machine (1) works as a motor. The second exciter (32) is operational when the synchronous electrical machine (1) works as a motor, by guaranteeing excitation power at each speed; the second exciter (32) is non-operational when the synchronous electrical machine (1) works as electric generator.
