FIELD: electrical engineering.
SUBSTANCE: device for winding/unwinding of a connection line made with possibility of fluid medium transportation or transmission of energy and/or signals comprises: coil (2) configured to receive said connecting line in a wound form; hollow through shaft (3), made with possibility of passage in it of said connecting line or fluid medium between rotary hinge and coil, wherein said hollow shaft (3) is integral with coil (2) for rotating said coil around longitudinal axis (X) of said shaft; at least one synchronous motor with permanent magnets for direct transmission of rotation, comprising a stator carrying windings (10) made with possibility of three-phase electric power supply, and a rotor carrying permanent magnets (11) facing stator windings (10). At least one rotor of said at least one synchronous motor is formed by central disc (24) of coil (2) or is rigidly connected to shaft (3).
EFFECT: providing high torque at low speed.
