BRUSHLESS STARTER/GENERATOR

A brushless starter generator is provided having a main electric machine and an exciter with a stator, comprising a direct-current stator winding and an alternating-current stator winding, and a rotor comprising rotor windings. An alternator regulator is connected to the direct-current stator winding via first and second direct-current electrical lines and supplies electrical power to the direct current stator winding when the starter generator operates in generator mode to generate a voltage at the output of the stator of the main electric machine. An SBU starter regulator supplies 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 has an electrical connection device to establish an electrical connection between the two electrical lines. The alternating-current stator winding is supplied with electrical power by the starter regulator.
