1. A device for winding/unwinding a link adapted to transport a fluid or transmit energy and/or signals, comprising:
a reel adapted to receive said link in wound form;
a hollow through shaft adapted to the passage of the link between a rotary joint and the reel, the hollow shaft being integral with the reel in order to drive said reel in rotation about a longitudinal axis of the hollow though shaft;
at least one permanent magnet synchronous direct drive motor, comprising a stator carrying windings adapted to be electrically three-phase powered and a rotor carrying permanent magnets facing windings of the stator, at least one rotor of said at least one synchronous motor being formed by a central disc of the reel;
an electronic speed variator adapted to vary the supply current of the windings of the stator;
a rotary joint coupled to an end of the hollow through shaft opposite the reel; and
a control/command system comprising a processing unit coupled or integrated to the electronic speed variator to control each permanent magnet synchronous direct drive motor.
