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.
Claims6
A propulsive electric motor set for aircraft, comprising
- an electrical energy source,
- an electric motor provided with a drive shaft on which is mounted a propeller,
- the electric motor comprising a first set of windings linked to said electrical energy source and arranged to provide a rotational drive function to rotate the drive shaft in a first direction,
- a second set of windings which, when the drive shaft is driven in rotation in a second direction opposite the first direction by an electric powering of the first set of windings, is arranged to provide an electric generation function configured to supply non-propulsive loads of the aircraft,
- wherein the propeller is coupled to the drive shaft such that the propeller is engaged with the drive shaft when the drive shaft is rotated in the first direction, and the propeller is disengaged with the drive shaft when the drive shaft is rotated in the second direction, and,
- wherein the propeller is free-wheel mounted on the drive shaft such that, when the drive shaft rotates in one direction, the drive shaft is engaged with the propeller and drives the propeller in rotation, and when the drive shaft rotates opposite to the direction through a phase-shift by π of an electric power supply of the first set of windings, the drive shaft rotates freely without driving the propeller.
