1. A device for braking/driving an aircraft wheel mounted to rotate on an undercarriage axle, the device comprising:

  • a stack of disks comprising disks that are constrained in rotation with the wheel and that alternate with disks that are constrained in rotation with a torsion tube;

    a support member mounted to rotate on the axle and constrained in rotation with the torsion tube;

    braking actuators carried by the support member for selectively pressing the disks together; and

    a drive member for selectively driving the support member in rotation;

    wherein the brake actuators are electromechanical actuators and in that the support member carries a secondary of a transformer having a primary arranged facing the support member while being stationary in rotation, the secondary being electrically connected to the actuators and the primary being adapted to being connected to a non-DC voltage source.
