  • Method of operating actuators simultaneously for moving aircraft flaps, an aircraft flap drive device, and an aircraft provided with such a device
    Patent number: 9114872
    Abstract: A method of operating actuators simultaneously for moving at least two aircraft movable aerodynamic surfaces, the method comprising the steps of: controlling the actuators to move the aerodynamic surfaces towards a predetermined position; during the movement, detecting a slowest actuator; and adapting the control of the actuators to match the actions of the slowest actuator. A drive device for aerodynamic surfaces and an aircraft including such a device.

  • Actuator having a multiphase motor, and a method of controlling such an actuator
    Patent number: 8957621
    Abstract: An actuator comprising at least one multiphase motor having phases facing a rotor secured to an outlet shaft associated with a braking member and provided with a connection to a movable element that is to be moved, the motors and the braking member being connected to at least one motor control unit for controlling the motors by powering their phases. The motor has at least four phases wound in such a manner as to avoid a neutral point, and in that the control unit has one single-phase inverter per phase and is arranged to implement a nominal, three-phase mode of control, and a degraded mode of control that enables the rotor to be driven in rotation by powering two non-collinear phases thereof.
