System for commanding and braking an articulated mobile element of an aircraft

A system for commanding and braking an articulated mobile element, the articulated mobile element being actuated by an electric motor, called motor, the command system being configured to receive commands for braking the articulated mobile element, called braking commands, and commands to stop braking the articulated mobile element, the command system being electrically connected to an electrical power supply, to the motor and to an electrical current consuming device, the command system includes electrical or electronic circuitry configured to:

• enable a first electrical connection to be established between the electrical power supply and said motor, to enable a second electrical connection to be established between said electrical power supply and said electrical current consuming device, and to inhibit a third electrical connection between said motor and said electrical current consuming device as long as no braking command is received and when a command to stop braking the articulated mobile element is received, and
• inhibit the first electrical connection between the electrical power supply and the motor, to inhibit the second electrical connection between the electrical power supply and the electrical current consuming device, and to establish a third electrical connection between the motor and the electric current consuming device when a braking command is received,
• wherein the electrical current consuming device of the system is used to effect de-icing of a surface when the electrical current consuming device is supplied with electrical energy.
