  • Propulsive electric motor set with electric generator
    Patent number: 11984839
    Abstract: A propulsive electric motor set for aircraft includes an electrical energy source and an electric motor provided with a drive shaft on which is mounted a propeller. The electric motor includes a first set of windings linked to the electrical energy source to provide a rotational drive function for the drive shaft. The electric motor further includes a second set of windings which, when the drive shaft is driven in rotation by an electric powering of the first set of windings, provides an electric generation function configured to supply non-propulsive loads of the aircraft. Thus, the non-propulsive loads of the aircraft can be electrically powered without any overload compromising the aerodynamics of the aircraft.
