Abstract: A brushless starter generator includes a main electric machine and an exciter comprising a stator, comprising a direct-current stator winding and an alternating-current stator winding, and a rotor comprising rotor windings; an alternator regulator that is intended to be connected to the direct-current stator winding via first and second direct-current electrical lines and intended to supply electrical power to the direct-current stator winding when the starter generator is operating in generator mode in order to generate a voltage at the output of the stator of the main electric machine and an SBU starter regulator supplying electrical power to the alternating-current stator winding and the stator windings of the main electric machine when the starter generator is operating in starter mode. The starter generator comprises an electrical connection device that is arranged and configured to establish an electrical connection between the two electrical lines.
