  • Patent number: 10113525
    Abstract: A method for controlling a starter-generator during a startup phase of a motor intended to be driven in rotation in a predetermined nominal direction by the starter-generator, the starter-generator comprises a stator comprising at least one polyphase stator winding and a rotor comprising at least one rotor winding coupled magnetically to the stator winding. The method comprises a step of starting up the motor, during which the polyphase stator winding and the rotor winding are supplied with electric power to start up the motor, the startup step preceded, when the motor is initially rotating in the direction opposite to the nominal direction, by a braking step, during which a current is drawn from at least one polyphase stator winding and the rotor winding is supplied with electric power.
