Abstract

The invention relates to a method for managing an electric motor ( 6 ) intended to drive rotationally a wheel ( 4 ) of an aircraft ( 1 ), the method comprising the step of short-circuiting the phases of the electric motor ( 6 ) when the aircraft ( 1 ) is in a period of deactivation of the motor ( 6 ) during which it is envisaged not using the electric motor ( 6 ).

Claims (6)

1. A method for managing an electric motor adapted to drive rotationally a wheel of an aircraft, the motor having phases (Ph) and adapted to being switched between periods of activation and deactivation, the method comprising:

short-circuiting the phases (Ph) of the electric motor when the aircraft is in a period of deactivation of the motor during which it is envisaged not using the electric motor.

2. The method for managing an electric motor according to claim 1 , wherein short-circuiting of the phases (pH) of the electric motor is performed by means of an electric switch of an inverter supplying a supply voltage to the electric motor.

3. The method for managing an electric motor according to claim 1 , wherein short-circuiting of the phases (Ph) of the electric motor is performed by means of at least one electromechanical switch connected to the phases of the electric motor.

4. The method according to claim 1 , wherein the deactivation period comprises a period during which a speed of the aircraft is greater than a predetermined speed threshold.

5. The method according to claim 1 , wherein the deactivation period comprises a take-off phase and/or a landing phase of the aircraft.
